Abstract:
Introduction: Empyema thoracis is an uncommon complication of childhood pneumonias but a common problem faced by a thoracic surgeon. Its management is still controversial, with a range of treatment options available and evolving gradually towards adoption of video-assisted thoracoscopic surgery (VATS) as the most commonly practiced one. Aim: The aim of this study was to review our experience in pediatric empyema thoracis. Methods: It was a retrospective review of the prospectively recorded data, spanning a period of 18 months in the Department of Cardio-Thoracic and Vascular Surgery in Manmohan Cardio-Thoracic Vascular and Transplant Center. Results: A total of 40 consecutive patients, 29 males and 11 females, aged 15 years or less were operated upon for a diagnosis of empyema thoracis made based on clinical, radiological and laboratory evidence. All of them were referred patients, mostly from pediatricians. VATS was undertaken in 36 of them, the remaining four treated by open approach. Deloculation sufficed in majority (26/40; 65%) of the patients which mostly (23/26; 90%) had either acute or subacute presentation. Decortication was required in 35% (14/40) of the patients. However, all of the patients but one had a successful outcome in terms of lung expansion, sterilization of the pleural cavity and absence of recurrence. There was no operative mortality. Conclusion: Surgical management of pediatric thoracic empyema is feasible and safe with favorable outcome. VATS is gradually becoming the more favored modality of operative management.

Abstract:
Objective Robotic-assisted surgery is increasingly being used in thoracic surgery. Currently, the Integrated Thoracic Surgery Residency Program lacks a standardized curriculum or requirement for training residents in robotic-assisted thoracic surgery. In most circumstances, because of the lack of formal residency training in robotic surgery, hospitals are requiring additional training, mentorship, and formal proctoring of cases before granting credentials to perform robotic-assisted surgery. Therefore, there is necessity for residents in Integrated Thoracic Surgery Residency Program to have early exposure and formal training on the robotic platform. We propose a curriculum that can be incorporated into such programs that would satisfy both training needs and hospital credential requirements. Methods We surveyed all 26 Integrated Thoracic Surgery Residency Program Directors in the United States. We also performed a PubMed literature search using the key word “robotic surgery training curriculum.” We reviewed various robotic surgery training curricula and evaluation tools used by urology, obstetrics gynecology, and general surgery training programs. We then designed a proposed curriculum geared toward thoracic Integrated Thoracic Surgery Residency Program adopted from our credentialing experience, literature review, and survey consensus. Results Of the 26 programs surveyed, we received 17 responses. Most Integrated Thoracic Surgery Residency Program directors believe that it is important to introduce robotic surgery training during residency. Our proposed curriculum is integrated during postgraduate years 2 to 6. In the preclinical stage postgraduate years 2 to 3, residents are required to complete introductory online modules, virtual reality simulator training, and in-house workshops. During clinical stage (postgraduate years 4–6), the resident will serve as a supervised bedside assistant and progress to a console surgeon. Each case will have defined steps that the resident must demonstrate competency. Evaluation will be based on standardized guidelines. Conclusions Expansion and utilization of robotic assistance in thoracic surgery have increased. Our proposed curriculum aims to enable Integrated Thoracic Surgery Residency Program residents to achieve competency in robotic-assisted thoracic surgery and to facilitate the acquirement of hospital privileges when they enter practice.

Abstract Objective The aim of this study is to improve rates of day of surgery admission (DOSA) for all suitable elective thoracic surgery patients. Design Lean Six Sigma (LSS) methods were used to enable improvements to both the operational process and the organizational working of the department over a period of 19 months. Setting A national thoracic surgery department in a large teaching hospital in Ireland. Participants Thoracic surgery staff, patients and quality improvement staff at the hospital. Intervention(s) LSS methods were employed to identify and remove the non-value-add in the patient’s journey and achieve higher levels of DOSA. A pre-surgery checklist and Thoracic Planning Meeting were introduced to support a multidisciplinary approach to enhanced recovery after surgery (ERAS), reduce rework, improve list efficiency and optimize bed management. Main Outcome Measure(s) To achieve DOSA for all suitable elective thoracic surgery patients in line with the National Key Performance Indicator of 75%. A secondary outcome would be to further decrease overall length of stay by 1 day. Results Over a 19 month period, DOSA has increased from 10 to 75%. Duplication of preoperative tests reduced from 83 to <2%. Staff and patient surveys show increased satisfaction and improved understanding of ERAS. Conclusions Using LSS methods to improve both operational process efficiency and organizational clinical processes led to the successful achievement of increasing rates of DOSA in line with national targets.

Abstract:
Background. The aim of this study is to investigate the effectiveness of preemptive thoracic epidural analgesia (TEA) comparing conventional postoperative epidural analgesia on thoracotomy.Material and Methods. Forty-four patients were randomized in to two groups (preemptive: Group P, control: Group C). Epidural catheter was inserted in all patients preoperatively. In Group P, epidural analgesic solution was administered as a bolus before the surgical incision and was continued until the end of the surgery. Postoperative patient controlled epidural analgesia infusion pumps were prepared for all patients. Respiratory rates (RR) were recorded. Patient’s analgesia was evaluated with visual analog scale at rest (VASr) and coughing (VASc). Number of patient’s demands from the pump, pump’s delivery, and additional analgesic requirement were also recorded.Results. RR in Group C was higher than in Group P at postoperative 1st and 2nd hours. Both VASr and VASc scores in Group P were lower than in Group C at postoperative 1st, 2nd, and 4th hours. Patient’s demand and pump’s delivery count for bolus dose in Group P were lower than in Group C in all measurement times. Total analgesic requirements on postoperative 1st and 24th hours in Group P were lower than in Group C.Conclusion. We consider that preemptive TEA may offer better analgesia after thoracotomy.

Abstract:
Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Recently, several retrospective studies have suggested that pulmonary complication is related with driving pressure more than any other ventilatory parameter. Thus, the authors compared driving pressure–guided ventilation with conventional protective ventilation in thoracic surgery, where lung protection is of the utmost importance. The authors hypothesized that driving pressure–guided ventilation decreases postoperative pulmonary complications more than conventional protective ventilation. Methods In this double-blind, randomized, controlled study, 292 patients scheduled for elective thoracic surgery were included in the analysis. The protective ventilation group (n = 147) received conventional protective ventilation during one-lung ventilation: tidal volume 6 ml/kg of ideal body weight, positive end-expiratory pressure (PEEP) 5 cm H2O, and recruitment maneuver. The driving pressure group (n = 145) received the same tidal volume and recruitment, but with individualized PEEP which produces the lowest driving pressure (plateau pressure–PEEP) during one-lung ventilation. The primary outcome was postoperative pulmonary complications based on the Melbourne Group Scale (at least 4) until postoperative day 3. Results Melbourne Group Scale of at least 4 occurred in 8 of 145 patients (5.5%) in the driving pressure group, as compared with 18 of 147 (12.2%) in the protective ventilation group (P = 0.047, odds ratio 0.42; 95% CI, 0.18 to 0.99). The number of patients who developed pneumonia or acute respiratory distress syndrome was less in the driving pressure group than in the protective ventilation group (10/145 [6.9%] vs. 22/147 [15.0%], P = 0.028, odds ratio 0.42; 95% CI, 0.19 to 0.92). Conclusions Application of driving pressure–guided ventilation during one-lung ventilation was associated with a lower incidence of postoperative pulmonary complications compared with conventional protective ventilation in thoracic surgery.

Abstract:
Objectives Symptoms associated with lung cancer and thoracic surgery might increase fall risk. We aimed to investigate: 1) balance, gait and functional status in people post-thoracic surgery compared to healthy controls; 2) perceptions of balance, gait and functional status. Methods Recruitment targeted older adults (≥50 years) who had undergone thoracic surgery for a diagnosis of lung cancer in the previous 3 months, and healthy age-matched controls. Dynamic and static balance, gait velocity, knee-extension strength and physical activity levels were assessed using the BESTest, Kistler force plate, GAITRite system, Biodex System 3 and CHAMPS questionnaire, respectively. Two-part semi-structured interviews were conducted post-surgery. Results Individuals post-surgery ( n = 15) had worse dynamic balance and gait, and lower levels of moderate/vigorous physical activity (MVPA) (all p<0.05) versus healthy controls ( n = 15). Strength did not differ between groups ( p > 0.05). No associations between BESTest and strength or physical activity existed post-surgery ( p > 0.05). Three themes were identified: 1) Symptoms affect daily activities; 2) Functional assessments alter perceptions of balance ability and 3) Open to supervised rehabilitation. Conclusion Balance, gait and MVPA are impaired post-thoracic surgery, yet balance was not viewed to be important in enabling activities of daily living. However, supervised rehabilitation was considered acceptable.

Abstract:
Introdução: A hiperidrose primária consiste em uma sudorese excessiva em regiões limitadas do corpo. A simpatectomia torácica videotoracoscópica é um dos tratamentos propostos para a hiperidrose primária palmar, aliando alto sucesso terapêutico com baixo risco. A fisiopatologia da hiperidrose primária ainda não está totalmente esclarecida. Objetivos: Analisar as características morfométricas dos gânglios simpáticos torácicos (G3), removidos cirurgicamente de pacientes portadores de hiperidrose palmar. Como controle foram utilizados os gânglios simpáticos, removidos no mesmo nível (G3), de pacientes doadores de órgãos por morte encefálica, sabidamente sem hiperidrose. Foram estudadas a estereologia e a apoptose celular e as fibras do sistema colágeno /elastina da matriz extracelular. Métodos: Estudo transversal, no qual foram incluídos 40 gânglios simpáticos torácicos (G3) removidos do hemitórax esquerdo, provenientes de pacientes com hiperidrose palmar (Grupo I), submetidos à simpatectomia videotoracoscópica, e 14 gânglios simpáticos de pacientes controle sabidamente sem hiperidrose (Grupo II), removidos por esternotomia mediana. Resultados: Em relação ao sexo, a proporção de mulheres e homens foi de 30:10, no Grupo I, e 7:7 no Grupo II, com p = 0,103. A idade no Grupo I, variou de 10 a 42 anos, com uma média de 23,73 (+ 7,51) e no Grupo II variou de 17 a 68 anos, com uma média de 37,57 (+ 16,65) , apresentando um p = 0,009. A média das células ganglionares nos pacientes do Grupo I foi de 14,25 (+ 3,81) e no Grupo II foi de 10,65 (+ 4,93) com p = 0,007. A média das células ganglionares coradas pela caspase (apoptose) no Grupo I foi de 2,37 (+ 0,79) e no Grupo II foi de 0,77 (+ 0,28) com p < 0,001. A mediana da área de colágeno corada pelo Picrosírius no Grupo I foi de 0,80 IQ (0,08-1,87) e no Grupo II foi de 2,36 IQ (0,49-5,98) com p = 0,061. Conclusões: Os pacientes portadores de hiperidrose primária palmar apresentam um maior número de células ganglionares no gânglio simpático, em relação aos do grupo controle. Há um número maior de células ganglionares simpáticas em apoptose na hiperidrose. Os pacientes portadores de hiperidrose apresentam menos colágeno no gânglio simpático
Introduction: Primary hyperhidrosis consists of excessive sweating in small areas of the body. The video-assisted thoracic sympathectomy is one of the suggested treatments for primary palmar hyperhidrosis, which combines high therapeutic success with low risk. The pathophysiology of primary hyperhidrosis is not fully understood yet. Objectives: Analyzing the morphometric characteristics of the thoracic sympathetic ganglion (G3) surgically removed from patients with palmar hyperhidrosis. The sympathetic ganglion removed at the same level (G3) from patients who are organ donors after brain death and who did not have hyperhidrosis were used as control. Stereology and cellular apoptosis, as well as the fibers of the collagen/elastin system of the extracellular matrix were subjected to scrutiny. Methods: Cross-sectional study, which included 40 thoracic sympathetic ganglion (G3) removed from the left hemithorax of patients who have palmar hyperhidrosis (Group I) and underwent video-assisted thoracoscopic sympathectomy, and also 14 sympathetic ganglion from control patients who did not have hyperhidrosis (Group II), which were removed with median sternotomy. Results: In regards to gender , the proportion of women to men was 30:10 in Group I and 7:7 in Group II, with p = 0.103. The age Group I ranged from 10 to 42 years, with an average of 23.73 (+ 7.51) years and in Group II, from to 17 to 68 years, with an average of 37.57 (+ 16.65) years, with p = 0.009. The average of ganglion cells in Group I was 14.25 (+ 3.81) and in Group II, 10.65 (+ 4.93) with p = 0.007. The average ganglion cells stained by Caspase (apoptosis) in Group I was 2.37 (+0.79) and in Group II, 0.77 (+ 0.28) with p = 0.001. The median collagen area by Picrosirius in Group I was 0.80 IQ (0.08-1.87) and in Group II, 2.36 IQ (0.49-5.98) with p = 0.061. Conclusions: Patients with primary palmar hyperhidrosis have an increased number of ganglion cells in the sympathetic ganglion in comparison to the control group. There are a higher number of sympathetic ganglion cells in apoptosis in hyperhidrosis. Patients with hyperhidrosis have less collagen in sympathetic ganglion

INTRODUÇÃO: A literatura tem postulado que a ventilação por pressão positiva não invasiva (VNI) pode facilitar o desmame de um grupo específico de pacientes. O objetivo deste estudo foi comparar a utilização da VNI como método alternativo na supressão da ventilação mecânica no pós-operatório de cirurgia cardíaca. MÉTODOS: Neste estudo prospectivo controlado e randomizado, foram estudados 100 pacientes submetidos a cirurgia de revascularização do miocárdio ou cirurgia valvar. Os pacientes foram admitidos na Unidade de Terapia Intensiva (UTI), sob ventilação mecânica e randomizados posteriormente em grupo estudo (n= 50), que utilizou VNI com dois níveis pressóricos após extubação, e grupo controle (n= 50), que utilizou a técnica convencional de supressão da ventilação mecânica. Foram analisados os tempos correspondentes à anestesia, cirurgia, circulação extracorpórea e ventilação mecânica na UTI. As variáveis gasométricas, hemodinâmicas e radiológicas foram avaliadas antes e após a extubação. RESULTADOS: Os grupos controle e estudo apresentaram comportamento semelhante quanto ao tempo de desmame ventilatório e as outras variáveis estudadas não apresentaram diferença estatística. A utilização da VNI por 30\' após a extubação, nos pacientes com atelectasias, promoveu diferença significativa na PaCO2 no grupo coronariano e na PaO2 no grupo submetido à cirurgia valvar. CONCLUSÃO: O tempo para supressão da ventilação mecânica foi similar nos grupos. Fatores extrísecos interferiram na evolução do desmame. O uso da VNI por 30 minutos após extubação apresentou diferença estatisticamente significante nas variáveis gasométricas em pacientes com atelectasias
INTRODUCTION: It was postulated that noninvasive positive pressure ventilation (NPPV) could facilitate ventilatory weaning in specific patients. The aim was to compare NPPV as alternative ventilatory weaning method with a standard ventilatory weaning protocol in the immediate postoperative period of cardiac surgery. METHODS: One hundred consecutive patients submitted to coronary artery bypass grafting or valvar surgery were addmitted in the Intensive Care Unit (ICU) and mechanicanically ventilated. They were randomly assigned to a study group (n=50) wich use NPPV witn bilevel presssure in the airways and a control group (n=50) witch used the conventional weaning thecnique. The outcome measures were anestesie, surgery, cardiopulmonar bypass and mechanical ventilation time. Arterial blood gases, hemodynamics and chest X-rays were assessed pre and post extubation. RESULTS: Weaning times were similar in both groups, and no differences were found in the studied variables. There were statistic significance considering PaCO2 in coronary and PaO2 in valvar group using NPPV 30\' after extubation, when atelectasis was detected. CONCLUSION: The ventilatory weaning time was similar in both groups. Extrinsics factors had interfered in weaning evolution. NPPV use during 30\' after extubation had statistical significance in gasometric variables in patients with athelectasis

Abstract:
Minimally invasive techniques in thoracic surgery have made great progress over the past 20 years and are still evolving. Many surgical procedures performed with large thoracotomy incisions in the past can now be performed with much smaller incisions. With many studies, the advantages of minimally invasive surgery have been clearly seen, and thus its use has become widespread worldwide. Today, minimally invasive surgical methods have become the first choice in the diagnosis and treatment of lung, pleural and mediastinal pathologies. Minimally invasive approaches in thoracic surgery include many different techniques and applications. In this chapter, current minimally invasive techniques in thoracic surgery are discussed and important points are emphasized in the light of the current literature.

Abstract:
Surgical treatment of thoracic aortic aneurysms has to account for anatomical location, patient risk profile, and the surgeon’s experience. Whereas endovascular treatment of the descending aorta has become a valid option for most patients and pathologies, open surgery remains the first choice to treat aneurysms of the aortic root, ascending aorta, and aortic arch and to treat patients with connective tissue disease in elective settings. Minimal invasive access is more frequently used to treat the aortic root, ascending aorta, and proximal aortic arch with excellent results. Long-term results of valve-sparing aortic root replacement undermine the recommendation to preserve the aortic valve, especially in young patients with tricuspid aortic valves. Aortic annulus stabilization either via valve reimplantation or external stabilization techniques in addition to aortic root remodelling ensures stable long-term results. Aortic root replacement using valved conduits remains a durable treatment option. Aortic arch surgery has been revolutionized by multiple technical solutions that facilitate surgical techniques (e.g. branched prefabricated grafts), extend treatment into the proximal descending aorta (e.g. frozen elephant trunk procedure), and minimize organ damage (e.g. cardiac and lower body perfusion during aortic arch repair). If endovascular treatment of the descending and thoracoabdominal aorta is not feasible, open surgical methods remain the standard of care and should routinely include protection methods to preserve organ function (e.g. left heart bypass, partial bypass). Treatment strategies in all patients should be discussed within a dedicated interdisciplinary team. Strict follow-up is mandatory.

Abstract:
The aim of this chapter is to propose a hybrid classification algorithm based on particle swarm optimization (PSO) to enhance the generalization performance of the adaptive boosting (AdaBoost) algorithm. AdaBoost enhances any given machine learning algorithm performance by producing some weak classifiers which requires more time and memory and may not give the best classification accuracy. For this purpose, PSO is proposed as a post optimization procedure for the resulted weak classifiers and removes the redundant classifiers. The experiments were conducted on the basis of ionosphere data set, thoracic surgery data set, blood transfusion service center data set (btsc) and Statlog (Australian credit approval) data set. The experimental results show that a given boosted classifier with post optimization based on PSO improves the classification accuracy for all used data. Also, the experiments show that the proposed algorithm outperforms other techniques with best generalization.

Abstract:
In recent decades, vascular surgery has seen the arrival of endovascular techniques for the treatment of vascular diseases such as aortic diseases (aneurysms, dissections, and atherosclerosis). The 3D printing process by addition of material gives an effector of choice to the digital chain, opening the way to the manufacture of shapes and complex geometries, impossible to achieve before with conventional methods. This chapter focuses on the bio-design study of the thoracic aorta in adults. A bio-design protocol was established based on medical imaging, extraction of the shape, and finally, the 3D modeling of the aorta; secondly, a bio-printing method based on 3D printing that could serve as regenerative medicine has been proposed. A simulation of the bio-printing process was carried out under the software Simufact Additive whose purpose is to predict the distortion and residual stress of the printed model. The binder injection printing technique in a Powder Bed Printer (PBP) bed is used. The results obtained are very acceptable compared with the results of the error elements found.

Abstract:
Both CMR and MSCT give almost unrestricted access to intra-thoracic structures, whereas ultrasonic access may be limited in ACHD patients. MSCT, generally using intravascular contrast, gives superior spatial resolution more rapidly than CMR, although the radiation dose is a concern in younger patients who may require repeated studies. MSCT gives better visualisation of epicardial coronary arteries and small collateral vessels, and can show conduit calcification or stent location clearly. It provides an alternative to CMR in patients with a pacemaker or ICD. CMR offers unrivalled versatility of acquisition methods without ionizing radiation, enabling measurements of biventricular function, flow, myocardial viability, angiography and more. A dedicated CMR service should be available in a centre specializing in ACHD care. Appropriate understanding is needed for the evaluation of congenitally and surgically altered circulatory function, for example after Fontan operations, surgery for transposition of the great arteries or tetralogy of Fallot.

Abstract:
Open endovascular and hybrid repairs have recently emerged as a method for treating the different segments of the thoracic aorta. A full or upper-mini median sternotomy is the usual approach for proximal aortic disease and proximal and transverse arch repairs. Other approaches, such as minimally invasive right thoracotomy, have also emerged. Until recently, a left thoracotomy and thoracoabdominal approach has been the sole approach for treating lesions of the descending and thoracoabdominal thoracic aorta. In the 1980s, the first aortic repair with a self-fixing endoprosthesis was performed. In subsequent years, the technique of using a stent graft to treat an abdominal aortic aneurysm, and subsequently thoracic aortic aneurysm, was popularized, followed by extensive development of this technology. The different techniques and modalities for treatment are discussed in this chapter.

Abstract:
Pulmonary resection has been a cornerstone in the management of patients with non-small cell lung cancer (NSCLC) for decades. In recent years, the popularity of minimally-invasive techniques as the primary method to manage NSCLC has grown significantly. With smaller incisions and a lower incidence of peri-operative complications, minimally-invasive lung resection, accomplished through keyhole incisions with miniaturized cameras and similarly small instruments that work through surgical ports, has been shown to retain equivalent oncologic outcomes to the traditional gold standard open thoracotomy. This technique allows for the safe performance of anatomic lung resection with complete lymphadenectomy and has been a part of thoracic surgery practice for three decades. Robotic-assisted thoracoscopic surgery (RATS) represents another major advancement for lung resection, broadening the opportunity for patients to undergo minimally invasive surgery for NSCLC, and therefore allowing a greater percentage of the lung cancer population to benefit from many of the advantages previously demonstrated from video assisted thoracoscopic surgery (VATS) techniques. RATS surgery is also associated with several technical advantages to the surgeon. For a surgeon who performs open procedures and is looking to adopt a minimally invasive approach, RATS ergonomics are a natural transition compared to VATS, particularly given the multiple degrees of freedom associated with robotic articulating instruments. As a result, this platform has been adopted as a primary approach in numerous institutions across the United States. In this chapter, we will explore the advantages and disadvantages of robotic-assisted surgery for NSCLC and discuss the implications for increased adoption of minimally invasive surgery in the future of lung cancer treatment.

Abstract:
Introduction: In adults, the thoracic duct carries about four liters of lymph per day, and its injury can lead to rapid accumulation in the pleural cavity, causing acute and chronic changes in lung dynamics. Thoracic duct injuries are uncommon and occur during surgical procedures in the thoracic region and trauma, such as esophagectomy, mediastinal and pleuro-pulmonary surgical procedures. Surgical injuries have been described after almost all types of thoracic surgical procedures, especially those performed in the upper left thoracic strait. The clinical diagnosis is based most often on the high output of the introduced chest drain, accompanied by a milky aspect. In addition, computed tomography, lymphoscintigraphy and lymphanangiography are possible methods for diagnosis. Clinical series on duct injuries after thoracic surgery report that in approximately 25% to 50% of cases spontaneous closure of the fistula occurs with conservative measures, after the introduction of parenteral nutrition or enteral diet with medium chain triglycerides. The other cases needed clinical and surgical treatment. Operative treatment consists of performing videothoracoscopy or right thoracotomy with identification of the lymphatic duct, followed by ligation. Case report: A 48-year-old woman, born in Santana do Parnaíba, state of São Paulo, with a diagnosis of breast cancer on the left, histological type of invasive breast carcinoma Luminal B, who underwent a modified radical mastectomy (Madden technique) on the left with immediate breast reconstruction. In the intraoperative period, important involvement of the left axillary lymph nodes was evidenced, which may have distorted lymphatic vessels and ducts. It evolved in the late postoperative period with high milky drainage in a suction drain in the left axillary region. Then, a hypothesis of thoracic duct injury was raised as a post-surgical complication. Biochemical analysis of milky secretion showed a high concentration of triglycerides and cytology describes the presence of proteinaceous material and macrophages. A conservative approach was adopted with adjustment of a hyperproteic, hypoglycidic and rich in medium chain triglyceride parenteral diet. The patient underwent lymphoscintigraphy, twenty days after the diagnostic hypothesis, but the fistula was not detected. Progressed with a decrease in the flow gradually until the drain was removed and she was discharged from the hospital in good condition. At the moment, the patient is undergoing adjuvant treatment for breast cancer.

Abstract:
Adolescent idiopathic scoliosis is the most frequent deformity of the growing spine. Scoliosis predominantly affects girls during the adolescent growth spurt. Untreated deformities become social stigmas, are crippling and can compromise organ function. Therefore, uncontrollable progression of curvature and related complex deformities require operative treatment. Surgery is currently the only way to effectively decrease the angle of curvature. Unfortunately, operative methods are still based on principles introduced by Hibbs in 1911 — long, stiff bony fusion of a major portion of the thoracic and/or lumbar spine.

Abstract:
Piracetam. a drug traditionally used for stimulating the telencephalon has a strong anti-aggregant, anti spasmodic and rheological action, due to its antisludge effect and the increase of the red cell deformability capacity. The authors show the interest of this substance in reconstructive surgery : Piracetam significantly increases the circulation in the flaps, reduces the zones prone to necrosis and allows for a faster skin expansion. The first three experiments have been performed on rats - on an epigastric flap with thoracic pedicle-. In the first one. we operated on 150 rats divided into 5 groups: a control series, and 4 series which received the following doses of Piracetam per os : 20.40.80 and 100 mg/100 g/day. The necrotic area, as measured daily, represents 13.8%+−2.6 (+− SEM) in the control series. 6% +− 0.8 in the series with 20 mg/100 g. 2.53% +− 0.66 in that with 40 mg/100 g. 1.67% +− 0.4 in thatwith 80 mg/100 g and 2.77% +− 1.96 in that with 100 mg/100 g. (all these percentages are expressed versus the overall surface). A thorough statistical study including the AN0VA table.“t” and regression tests shows that these differences are significant at 0.0001 for the 40 mg/100 g dosis and 0.0000 for the 80 mg/100 g dosis. A second experiment measured the local blood flow in 4 areas of the flap from its thoracic basis towards its epigastric point thanks to the radio-active microsphere technique described 1n rats by He Oevitt and Mallck. Measures were carried out on 60 rats divided into 3 groups : control series without flap, series with a flap at the second post-operative day without Piracetam. series with a flap at thesecond post-operative day with Piracetam.With Piracetam. the increase of the bloodflow in the thoracic part proximal to th flap (zone 1) is of 60% +− 13 (p < 0.0000). that of zone 2 of 72% +< 20 (p < 0.0008). that of zone 3 of 92% +< 23 (p < 0.0003), and finally that of the epigastric zone 4 of 117% +− 40 (p <0.004) (vs the overall surface). A thirdexperiment measured the temperature difference of these 4 zones by means of a, thermocouple according to the method described by Jones in 1983 and it compared the results obtained with the flow measured by microspheres. Finally, in a last experiment, the blood flow in expanded tissueswith- and without- piracetam 40 mg/100 gwas measured with a laser-doppler.Therefore it was concluded that piracetam is a useful drug to prevent necrosis in flaps. It can also be used to expand tissues more quickly.
