Full textThe pathophysiology of pulmonary hypertension (PH) remains unclear. Différent mechanisms are involved in the vascular remodeling in PH. The disruption of cellular interactions and the activation of specific signalling pathways contribute to the development and progression of the structural changes in small pulmonary arteries. Moreover, environmental and genetic factors may predispose to this vascular disease.The alterations of pulmonary micro-vessels and of bronchial circulation in chronic thromboembolic disease and in pulmonary arterial hypertension represent a new finding in such diseases, with potential implications in the managment of patients. Pulmonary microvascular changes and bronchial circulation remodeling are also idenfied in selected animal models of PH

O objetivo deste estudo foi descrever a técnica de venografia retrógrada podal em vacas, comparando os acessos da veia digital dorsal comum III com a digital comum II ou IV, nos membros torácicos e pélvicos mediante a administração de dois diferentes volumes de contraste. Foram utilizados 53 membros torácicos e pélvicos de 14 vacas, contidas em decúbito lateral no tronco com o torniquete de borracha posicionado a 5 cm do paradígito. Administrou-se 10 mL do diatrizoato de meglumine em 24 membros (grupo 1), sendo 13 na veia digital dorsal comum III pelo acesso 1 (A1) e 11 na digital II ou IV no acesso 2 (A2). No grupo 2, administrou-se 20 mL em 29 membros, sendo 15 pelo A1 e 19 no A2. Após a administração do contraste, as radiografias foram repetidas a cada 20 segundos até 120 segundos, na projeção dorso palmar/plantar 0°. O grau de preenchimento vascular foi maior no grupo 2, independente do acesso venoso, do membro ou momento. Não houve diferença significativa no grau de radiopacidade das imagens radiográficas quando comparado o acesso venoso, momento e membro de ambos os grupos. Conclui-se que a administração de 20 ml de contraste apresentou melhor preenchimento e radiopacidade, não havendo diferença entre 20 e 120 segundos após a administração do contraste na qualidade radiográfica independente do acesso venoso
In cattle the foot retrograde venography is rarely described, compared with the equine species. The aim of this study was to describe the technique of retrograde venography foot in cows, comparing the approaches of the dorsal common digital vein III with the digital commons II or IV, thoracic and pelvic by administering two different volumes of contrast members. Were used fifty tree fore and hindlimbs of 14 cows, contained in the lateral position on the trunk with rubber tourniquet placed at 5 cm from paradígito were used. Was administered 10 mL of diatrizoate meglumine 24 members (group 1), 13 dorsal common digital vein III for access 1 (A1) and 11 digital II or IV access 2 (A2). In group 2 was administered 20 mL 29 members, 15 by 19 in A1 and A2. After contrast administration, the radiographs were repeated every 20 seconds until 120 seconds, back projection on the palmar/plantar 0°. The degree of vascular filling was greater in group 2, independent of venous access, member or moment. There was no significant difference in the degree of radiopacity of radiographic images when compared to the venous access, time and a member of both groups. We conclude that administration of 20 ml of contrast showed better filling and radiopacity, with no difference between 20 and 120 seconds after contrast administration in independent radiographic quality venous access

Full textThe role of the venous system is central to cardiovascular fonction, yet, in terms of scientific literature, it appears to be the "poor relation" compared to the heart or arterial system. This is true both for the physiological understanding of venous hemodynamics and for the pathophysiological analysis of chronic venous disease and more particularly when the link is made with exercise. The aim of our investigations was to better understand the adaptations of the venous system during physical activity and during the post-exercise recovery period and, to evaluate the impact of chronic venous disease on physical activity and vice versa. We have studied the acute effects of physical activity on venous hemodynamics (evaluation of the calf venous pump), and the effects of various recovery methods ( compression, immersion, calf low frequency electrical stimulation), and we have also explored the consequences of chronic venous disease upon physical activity through the analysis of venous claudication. The main results of our work enabled a better understanding of the adjustments in venous hemodynamics linked to exercise in healthy subjects and to better understand the pathophysiological consequences of high venous pressure on the microcirculation of patients with chronic venous disease. Our findings also provide a detailed understanding of venous hemodynamics during post-exercise recovery and the positive effects of recovery methods on both performance and vascular adjustments. The interdependence of the different organs and tissues (heart, arteries, microcirculation, veins) of the cardiovascular system is an essential element highlighted in this work. Thus, we demonstrated that venous hemodynamics could not be analyzed in isolation, but rather that it should be assessed as a whole by measuring implications on cardiac filling and on tissue exchange, and looking for the part of the splanchnic system and limbs system on systemic venous return. ln conclusion, we have filled some of the gaps in the literature by examining the relationships between veins, physical exercise, recovery and venous pathology. However, questions remain regarding the methodology to be implemented for the evaluation of the venous system and the chronic effects of the intensive physical activity practice on the chronic venous disease prevalence

Full textTreatment for varicose veins (VV) is insufficiently evidence based and recurrence rates are high. The aim of this thesis was to study the long-term results after VV surgery, risk factors for recurrences and the effect of preoperative duplex scanning on recurrence rate, quality of life (QoL) and costs.
In a follow-up study 89 patients with 100 legs operated on for VV 6–10 years earlier were re-examined with duplex, in 13 cases also with varicography. 57% had incompetent vessels in the groin visible with duplex, equally well defined by varicography. Residual branches could not be differentiated from new vessel formation. The recurrence rate did not correlate to the surgeon’s level of experience or perioperative difficulties at primary surgery.
In a prospective randomized study 293 patients (343 legs) were operated on for primary VV with or without preoperative duplex. Duplex was done postoperatively, at 2 months and 2 years. QoL was measured with SF-36 preoperatively, at 1 month, 1 year and 2 years.
After 2 years the number of reoperations were 2 in the group with preoperative duplex and 14 in the group without (p=0.002). Incompetent veins were seen in the saphenofemoral or saphenopopliteal junction in 19 and 53 legs respectively (p<0.001).
Preoperative QoL was worse in the VV patients compared to a reference population, and was normalised 2 years postoperatively. The improved surgical result in the duplex group was not reflected in a significantly higher QoL.
The lower costs for redo surgery in the duplex group did not offset the costs for duplex, partly due to more extensive primary surgery.
A significant proportion of recurrences after 2 years was new vessel formation and progression of disease. Preoperative perforating vein incompetence did not influence recurrence rate, and was abolished without specific interruption in 60% at 2 years postoperatively.

Full textThe external form of the liver is extremely varied among the mammals. These architecture types present an own vascular arrangements, in agreement with the largest or smaller degree of fissuring of this organ among the species, assuming private importance in the establishment of the port-bilo-arterial segmentation. This importance however, is due mainly to the fact that the hepatic veins don\'t obey the same itinerary of the functional circulation what it impels us to establish a new pattern to segmental. By means of observations of pieces isolated, fastened in situ, as well as of plastic molds of the hepatic veins system obtained by means of corrosion and of pieces injected with Neoprene latex and later on dissected, we can identify five main hepatic veins. These veins can be divided in two groups: the segmental veins, that draining a segment just, and intersegmental veins, that draining more than a segment. They are them: left intersegmental vein, formed by 2 or 3 lefts segmental lateral veins that draining the left lateral lobe (segment II) and 1 to 5 left segmental paramedians veins, that draining the left medial lobe (segment III), sagital intersegmental vein, formed by the confluence among the segmental vein of the quadrate lobe (segment IV) and the segmental medial vein of the right medial lobe (segment V), segmental vein of the caudate process (segment VII), draining the caudate process and the right segmental vein, formed by 2 or 3 segmental lateral right veins that draining the right lateral lobe (segment VI). the segmental vein of the papillary process (segment I) comes as only vessel that ends in the cava caudal vein.

Introduction: The frequency of events of total anomalous pulmonary venous connection (TAPVC) varies in the different series from 5.9 to 7.1 / 100 000 live births, representing 1 to 5% of cases of congenital heart disease. Since the current care has developed; the need to approach possible late complications, such as arrhythmias, is important. Objective: To evaluate the distribution of arrhythmias and possible related variables in patients in the late postoperative TAPVC. Method: Medical record review and clinical and noninvasive arrhythmia evaluation were used for data analysis of 20 patients who underwent isolated TAPVC. Statistical analysis for the detection of related variables. Results: Clinical and echocardiographic evaluations showed no significant changes. Of the 20 patients, 13 (65%) showed some abnormalities for age according to the 12-led EGC. By Holter, six patients (30%) presented atrial and / or ventricular ectopy with higher frequency than mild. Junctional rhythm and 2: 1 atrioventricular occurred in one patient (5%). Analyzing the criteria for sinus node dysfunction, bradycardia was observed by Holter in 30% of the patients. There were no pauses longer than two seconds. By Ergometric test, 82% of children had chronotropic deficit. Follow-up more than 60 months and abnormal ECG were related to the presence of arrhythmias. Conclusion: The long term follow-up of patients undergoing anomalous pulmonary venous connection showed that regardless of the good clinical and echocardiographic results, the possibility of occurrence of atrial and / or ventricular arrhythmias highlight attention to the need for maintenance of regular clinical evaluations.
Introdução: A frequência de ocorrência da conexão anômala total de veias pulmonares (CATVP) varia nas diversas séries entre 5,9 a 7,1/100 mil nascidos vivos, representando 1 a 5 % dos casos de cardiopatia congênita. A evolução nos cuidados atuais leva à necessidade de abordagem de eventuais complicações tardias, como as arritmias. Objetivo: Avaliar a distribuição das arritmias e possíveis variáveis relacionadas em pacientes em pós operatório tardio de CATVP. Método: Análise dos dados de 20 pacientes operados de CATVP isolada, com revisão de prontuário e avaliação clínica e não invasiva de arritmias. Estudo estatístico para detecção de variáveis relacionadas. Resultados: As avaliações clínica e ecocardiográfica não evidenciaram alterações significativas. O eletrocardiograma (ECG) de 12 derivações apresentou anormalidades para a idade em 13 dos 20 pacientes estudados (65%). Ao Holter, 6 pacientes (30%) apresentaram ectopias atriais e/ou ventriculares de frequência maior que discreta. Ritmo juncional e bloqueio atrioventricular 2:1 aconteceram em um paciente (5%). Analisando-se os critérios para disfunção do nó sinusal, observou-se bradicardia ao holter em 30% dos pacientes. Não houve pausas maiores que 2 segundos. Ao teste ergométrico, 82% das crianças apresentaram déficit cronotrópico. Seguimento maior que 60 meses e ECG anormal relacionaram-se à presença de arritmias. Conclusão: O seguimento em longo prazo de pacientes operados de conexão anômala total de veias pulmonares mostrou que independentemente dos bons resultados clínicos e ecocardiográficos, existe a possibilidade de ocorrência de arritmias atriais e/ou ventriculares, chamando a atenção para a necessidade de manutenção de avaliações clinicas regulares.

Full textEmpirical methods play an important role in the field of geomechanics due to the recognized complexity of the nature of rock mass. This study aims to analyze the applicability of empirical design methods in vein-shaped hydrothermal mining deposits (narrow vein) using Bieniawski and Barton classification systems, Mathews stability graphs, Potvin and Mawdesley geomechanics classification systems, and mining pit dilution based on the equivalent linear overbreak/slough (ELOS). In most cases, these methods are applied without understanding the underlying assumptions and limits of the database in relation to the inherent hidden risks. Herein, the dilutions obtained using the empirical methods oscillate between 8% and 11% (according to the frontal dimension), which are inferior to the operative dilution of the mine at 15%. The proposed model can be used as a practical tool to predict and reduce dilution in narrow veins.
