Resumen
Environ deux tiers des patients atteints de syndrome de détresse respiratoire aiguë (SDRA) présenteront une instabilité hémodynamique avec recours aux vasopresseurs. Sous ventilation mécanique, la diminution de précharge du ventricule droit (VD) suite à l’augmentation de la pression pleurale et l’augmentation de la postcharge du VD secondaire à l’élévation de la pression transpulmonaire seront des phénomènes exacerbés en cas de SDRA. Les risques encourus sont une diminution du débit cardiaque global et l’évolution vers un cœur pulmonaire aigu (CPA). Le contrôle de la pression motrice, de la pression expiratoire positive et la lutte contre l’hypoxémie et l’hypercapnie auront un impact autant respiratoire qu’hémodynamique. L’échographie cardiaque tient un rôle central au sein du monitorage hémodynamique au cours du SDRA, à travers l’évaluation du débit cardiaque, des différentes pressions de remplissage intracardiaques et le diagnostic de CPA. Le cathéter artériel pulmonaire est un outil de monitorage complet, indiqué en cas de défaillance cardiaque droite ou hypertension artérielle pulmonaire sévère ; mais le risque d’effets indésirables est élevé. Les moniteurs utilisant la thermodilution transpulmonaire permettent un monitorage du débit cardiaque en temps réel et sont d’une aide précieuse dans l’évaluation du statut volumique. L’évaluation de la précharge dépendance ne doit pas s’effectuer sur les variabilités respiratoires de la pression pulsée ou du diamètre des veines caves, mais à travers l’épreuve de lever de jambe passif, le test d’occlusion télé-expiratoire ou encore les épreuves de remplissage titrées.

Resumen
The gold-palladium mineralization of the Chudnoe deposit is represented by mineralized veined zones in fractured and brecciated rhyolites of the Riphean-Vendian age. Native gold and palladium minerals are concentrated mainly in veins of Cr-containing muscovite (fuchsite), in which allanite is present in small amounts; quartz, albite, calcite, potassium feldspar, titanite, apatite, zincochromite and other minerals are also found. Veins of allanite-albite-quartz composition are found in ore zones, in some cases containing abundant fuchsite secretions. It has been established that quartz-albite-allanite-fuchsite and other fuchsite-containing veins are the result of the superposition of quartz-albite vein execution on previously formed gold-bearing fuchsite veins. Quartz-albite vein material fills central parts of the combined veins and cements fragments (xenoliths) of fuchsite, while in some cases part of the gold was redeposited and fixed in the quartz-albite part of the veins. Based on the study of the decomposition structures of solid solutions in native gold, it was previously established that the temperature of gold formation in fuchsite veinlets exceeded 220 °C. The deposition temperature of the main part of the quartz-albite veins was noticeably lower. The homogenization temperature of fluid inclusions in vein minerals (quartz, albite, allanite, calcite) was mainly in the range of 96—168 °C, solutions were enriched with magnesium and calcium chlorides. Under these conditions, allanite, apatite, monazite, xenotime, and molibdosheelite were formed and redeposited, and fuchsite recrystallized.

Resumen
Introduction : L’oreillette unique est une cardiopathie congénitale rare. Le traitement est la chirurgie. Son pronostic est bon après chirurgie. Le but de ce travail est de rapporter un cas d’oreillette unique. Observation : Nous rapportons l’observation d’une jeune femme âgée de 17 ans issue d’un mariage non consanguin sans antécédents, présentant depuis quelques mois une dyspnée d’aggravation progressive. L’examen physique avait révélé un souffle latérosternal de 5/6. La radiographie pulmonaire mettait en évidence une hyper vascularisation pulmonaire et un ICT à 0,60. Echocardiographie : oreillette unique, insuffisance tricuspide grade II, FE : 45 %, PAPS : 63 mm hg. Exploration per-opératoire : veine cave supérieure gauche se jetant dans un sinus coronaire dilaté de topographie anormale et oreillette unique par absence complète du septum interauriculaire. Elle a bénéficié de la fermeture de la communication inter auriculaire par un patch péricardique autologue sous circulation extracorporelle. Les suites post opératoires étaient simples. Conclusion : L’oreillette unique est une variété rare de communications inter-auriculaires caractérisée par l’absence du septum inter-auriculaire. Elle peut être isolée ou associée à d’autres cardiopathies congénitales.

Resumen
The prospective study was conducted from December 2022 to May 2023 to assess patient-based, radiological, and clinical outcomes after conventional surgery and radiofrequency ablation for great saphenous varicose veins. Patients were randomly divided to undergo conventional surgery or RFA. American Society of Anesthesiologists fitness grade, Venous Disability Score (VDS), Total Clinical Severity Score (TCSS), Michael's, and CEAP clinical classes were recorded. VEINES-QoL/Sym questionnaire and Aberdeen Varicose Vein Questionnaire were used to estimate baseline QoL. Patients were called for follow-up at the end of 1st and 5th week. The study was conducted on a total of 110 patients. Patients were randomly divided; 57 underwent RFA, and 53 underwent conventional surgery. Results showed that the difference between both groups regarding anesthesia induction, recovery, and discharge from surgery was insignificant. RFA had significantly longer total theater time compared to conventional surgery. Duplex imaging showed that RFA resulted in successful ablation except in two cases where veins had segmental brisk flow. These cases were retreated successfully. Conventional surgery only had the problem of incomplete stripping (6 cases). Post-operative pain, bruising, and the need for analgesia were significantly higher following conservative surgery. Patients in the RFA group returned to work and normal activities more quickly than the conventional surgery group. It is concluded that RFA had a longer intervention time but significantly better outcomes than conventional surgery.

Resumen
Dural arteriovenous fistulas (AVF) are rare intracranial vascular malformations, consisting of communications between dural venous arteries and sinuses, meningeal veins, cortical veins, or combinations thereof. In most cases the etiology is unknown. The clinical presentation is determined by the location and mainly by the drainage pattern. The recognition of this rare clinical entity is essential for an early diagnosis and intervention, to avoid the potentially serious complications of the disease, such as, intracranial hypertension, vascular dementia, hemorrhage, among others.

Resumen
La plupart des etudes comparatives in vitro des filtres de veine cave ont essentiellement ete axees sur leur taux d'efficacite de capture et d'obstruction, alors que tres peu se sont orientees vers l'analyse des perturbations hydrodynamiques suite a leur mise en place dans la veine cave inferieure. Cette etude, associant l'experimentation in vitro et la modelisation numerique, s'inscrit dans ce dernier domaine d'etude. Des analyses experimentales de la structure de l'ecoulement a travers quatre filtres caves de formes et concepts differents, et obstrues partiellement ou non par des caillots de diverse geometrie, ont ete effectuees. Ces filtres, places dans une conduite cylindrique, sont soumis a differents regimes d'ecoulement (permanent puis pulse proche de celui observe in vivo lors des cycles respiratoires). On determine dans un premier temps les perturbations hydrodynamiques generees puis dans un second temps leur evolution au cours du cycle pulse. Ces diverses etudes montrent notamment l'influence du nombre et de la geometrie des branches. Pour valider et completer ces etudes effectuees par trois methodes de visualisations particulaires (ptv, velocimetrie ultrasonore doppler), plusieurs modeles numeriques ont ete developpes. Ces simulations nous permettent d'avoir acces a des informations inaccessibles experimentalement telles que cisaillements et forces appliquees sur les divers obstacles places dans l'ecoulement. Du fait du comportement rheologique complexe du sang, l'etude des perturbations permet de determiner les possibles sites thrombogenes propres a chaque filtre et donc d'evaluer les risques potentiels posterieurs a l'insertion de ces filtres dans la circulation sanguine, a savoir les phenomenes de recidive d'embolie pulmonaire et d'embolisation fibrinolytique.

Resumen
Thrombosis of cortical veins and/or dural venous sinuses (CVT) is a rare but potentially devastating condition. CVT is more common in women and is strongly associated with pregnancy and the postpartum period, likely due to numerous procoagulant changes during this time. CVT can cause a wide range of symptoms depending on location of thrombosis. Clinical manifestations can include headache, cranial nerve deficits, seizures, and venous infarction with associated focal neurologic deficits. Severe cases may progress to coma and death, emphasizing the importance of early diagnosis and treatment. The approach to management of CVT during pregnancy and the postpartum period must be tailored to prevent complications to the mother and child. This chapter addresses the pathogenesis, clinical manifestations, diagnosis, and treatment of CVT in pregnancy and the postpartum period.

Resumen
Intestinal ischaemia is caused by occlusion of the visceral arteries, thrombosis of the mesenteric veins, or by (low-flow) non-occlusive mesenteric ischaemia (NOMI). Each condition has a specific diagnostic and therapeutic work-up and prognostic significance. The incidence of acute mesenteric infarction is as low as 0.63 cases/100,000 person years, but overall mortality rates remains high at 74%. In general, a high index of suspicion is necessary and should be followed by administering therapeutic low molecular weight heparin or systemic heparin infusion. In these patients resuscitation and organ support are essential, but should not delay diagnostic work-up, including CT-angiography. With arterial occlusion, revascularization should be performed if indicated, preferentially using endovascular techniques prior to laparotomy. For venous occlusion, thrombolytic therapy directly into the superior mesenteric artery or venous thrombectomy can be performed, followed by laparotomy. The treatment of NOMI is to treat the underlying cause.

Resumen
Congenital diaphragmatic hernia (CDH) is characterized by malformation of the diaphragm, allowing for herniation of abdominal contents into the thoracic cavity. The most significant sequelae of this herniation are pulmonary hypoplasia and pulmonary hypertension, both contributing to significant morbidity and mortality. Multiple strategies exist to minimize respiratory compromise and improve outcome in a patient with CDH, including fetal intervention in selective cases, medical and pharmaceutical management, advanced ventilation strategies, extracorporeal membrane oxygenation (ECMO), and complete surgical repair. Veno-arterial ECMO (circuit between the internal jugular vein and the carotid artery) is used in infants who are unstable and require aggressive cardiopulmonary support, and veno-venous ECMO (circuit with a double lumen catheter in the internal jugular vein) is used in infants who only need respiratory support.

Resumen
Septic (suppurative) thrombophlebitis is venous thrombosis in the setting of bacteremia. There is usually a degree of perivascular inflammation seen on histology. Septic thrombophlebitis occurs most commonly with intravenous catheters. However, most cases of infection related to intravenous catheters are not complicated by septic thrombophlebitis. Catheter-related septic thrombophlebitis includes erythema, tenderness, and/or drainage at the site of an intravenous catheter. Jugular vein septic thrombophlebitis, also known as Lemierre’s syndrome, is a subset of septic thrombophlebitis. This condition can affect otherwise young, healthy adults and is often preceded by pharyngitis with tonsillar and peritonsillar involvement, dental infections, or infectious mononucleosis. Presentation of jugular vein septic thrombophlebitis includes high fevers, rigors, respiratory distress, ulceration or erythema of the oropharynx, and tenderness and swelling of the neck. Primary treatment of thrombophlebitis includes removal of infected materials, intravenous antibiotics, and possible anticoagulation.

Resumen
When attempting to understand the cultural politics of gender in Europe after 1945, some readers will undoubtedly anticipate answers to the following question: To what extent have the impact of the Cold War, the rise of feminism, the supposedly sexually liberated 1960s, the emergence of ‘post-feminism’, and the putative ‘crisis of masculinity’ changed attitudes towards gender and sexuality, and impacted on gender-related legislation? This article examines the cultural politics of gender at the juncture of globalisation, securitisation, and Europeanisation, and explores how Europeans have ‘fashioned their distinction’ in attempts to reconstitute themselves as global citizens in a multi-ethnic, post-imperial Europe. By focusing on the commoditisation of white femaleness, the coercive normalisation of Muslim masculinity, the ‘liberation’ of the veiled Muslim woman, and the eroticisation of black men in white consumer fantasy, the article's analysis of exemplary cases demonstrates how gendered imaginaries in Europe are forged by a complex dialogue with race, nation, capitalism, sex, and security.

Resumen
Pulmonary hypertension is a haemodynamic and pathophysiological condition defined as an increase in the mean pulmonary arterial pressure of ≥25 mmHg at rest, as assessed by right heart catheterization. In fact, while transthoracic echocardiography may provide clues on the presence of pulmonary hypertension, the haemodynamic evaluation offers a more precise and comprehensive assessment. Pulmonary hypertension is heterogeneous from a pathophysiological point of view, and the diversity is reflected in the haemodynamic definitions. The different haemodynamic forms of pulmonary hypertension can be found in multiple clinical conditions which have been classified into six main groups and at least twenty-six subgroups. Each main clinical group shows specific pathological changes in the lung distal arteries, capillaries, and small veins. If we combine the haemodynamic and clinical heterogeneity, we understand the complexity of an accurate diagnosis in the individual patient which is crucial for the prognostic assessment and treatment strategy. In addition, the concomitant presence of different haemodynamic and clinical mechanisms cannot be excluded in individual cases (e.g. in patients with congestive heart failure and associated lung diseases). The presence of pulmonary hypertension, as defined above, is always an ominous prognostic sign, even if the severity may differ according to the haemodynamic changes and underlying clinical condition. The therapeutic approach also is markedly different, according to the clinical group, and symptomatic and haemodynamic severity. For these reasons, the four more frequent clinical groups are discussed individually, while the classifications are described in the Introduction section.

Resumen
Intracerebral hemorrhage (ICH) during pregnancy and the puerperuim is a rare but potentially devastating complication of pregnancy. It is a condition that requires emergent medical attention and inclusion of multiple medical and or surgical specialists. Accurate diagnosis based on clinical exam and supported by neuroimaging techniques is essential. Medical management is the mainstay in most cases including post-hemorrhage blood product consideration, reversal agents if on anti-coagulation, blood pressure control, cerebral edema management, and treatment of seizures. Circumstances also arise in which surgical intervention is needed. It is important to also discuss optimal timing of delivery. Postpartum care including close blood pressure control, deep vein thrombosis prophylaxis (DVT), and risk factor modification are important. Ethical situations sometimes arise and must also be considered with respect to the mother and child.

Resumen
171 chronic arterial occlusions and 86 acute venous thromboses were treated by systemic ultrahigh streptokinase (UHSK) infusions. 38% of the patients were over 65, 27% over 70 years of age. The UHSK scheme consisted of a 1.5 million units SK per hour maintenance infusion over a period of 6 hours. 46% of the patients received one, 47% two, 6% three, and 1% four series (one series per day). 81% of the arterial patients had a history of less than 3 months. In 54% of the cases PTA followed UHSK treatment for dilation of a residual stenosis or removal of occlusion residues still persistent. In the venous patients the most proximal location was distributed as follows: calf veins 1%, femoral vein 57%, iliac vein 28%, subclavian vein 14%. The average thrombosis history was 8 days.Clearance rates of chronic arterial occlusionsBy setting up of sub-groups more favorable results were calculated. For exemple, a femoral occlusion group consisting of cases with a history shorter than 6 weeks and 2 or 3 calf arteries patent displayed a clearance rate of 77%, a figure much higher than the overall femoral resultClearance rates of deep venous thrombosisThe thrombosis duration played a significant role for thrombosis dissolution. The average occlusion history was 6 days in the total clearance group compared with 12 days in the unsuccessful cohort.

Resumen
Methods : in this prospective study, real time B Mode ultrasound imaging (USI) was compared to bilateral ascending contrast venography, double blindly, in 430 patients suspected of deep vein thrombosis (DVT) or pulmonary embolism.A complete scan of the venous system from the inferior vena cava to the calf veins, was performed with a high resolution duplex system (DIASONICS DRF 400) and coupled systematically with a C.W. Doppler examination. The results obtained by USI were thus compared to the venograms performed on a total of 854 legs.Results : there are corresponding results in 95% of the legs (808/854). If we consider venography as the standard of reference, the sensitivity of USI is 98% (325/333) and the specificity 94% (483/514). Isolated calf vein thrombosis are detected in 91% (84/92) of the legs and proximal DVT in 100% (241/241) in this series whatever the topography and the extension of the thrombosis and whatever the degree of the obstruction of the vein.Discrepancies found in 46 legs are related to :- 8 DVT located in the calf (6 in the presumed healthy leg) diagnosed only by venography.- 27 DVT (18 distal, 9 femoral or iliac) detected only by USI- 9 doubtful examinations with USI not confirmed by venography- 2 doubtful venograms with negative USI test.Comments : Calf vein thrombosis especially located in the soleal sinuses and the gastrocnemius with in most cases the direct image of the thrombus are more often detected by USI provided that the technique and the equipment are appropriate.The absence of visualisation of venous segments with venography is not specific of venous thrombosis. These veins non affected by the thrombosis are not filled by the contrast medium when located above in occluded ilio-femoral or ilio-caval junction or when they are the site of extrinsic compression. The direct image of the vein and the surrounding structures obtained with USI enhances the diagnostic sensitivity and specificity and provides precision of the exact extension of the thrombosis.Due to these differences, can venography still be considered as the standard of reference in the diagnosis of DVT and their precise localisation ?

Resumen
Abstract Blood vessels on the cortical surface of the temporal lobe of the cerebrum are frequently damaged in head impact, such as occurs in falls, contact sports, or vehicular collisions. An understanding of the mechanical behavior of these arteries and veins, as well as their limiting loads, is required for a proper understanding and modeling of such traumatic processes—as well as providing substantial assistance in preventive measures and even diagnosis and treatment. Measurements have been performed to obtain the quasi-static and dynamic axial stress-strain characteristics up to and including failure of cortical arteries and veins resected from the temporal lobes of living humans. Results show a notable difference in the behavior of arteries and veins, and somewhat smaller differences — in some cases inconclusive — between static and dynamic comportment. A critical difference between this investigation and the few previous studies of cerebral vessels is the examination of vessel properties under conditions as close as possible to those of the living human, in contrast to studies substantially subsequent to the acquisition of the samples, such as autopsy material, which are reputed to exhibit substantially different properties.

Resumen
It has been proposed that a decreased synthesis of PGI2 may be a critical factor in the development of thrombosis on the basis that generation of PGI2 may under ly the ability of normal vessels to resist platelet adhesion. Vascular synthesis of thromboxane A2 (Tx) has been believed to be nonexistent or of very slight degree and of no physiological or pathological importance. Recent studies, however, have shown that other soirees of Tx than platelets may exist. Veins from patients with deep venous thrombosis, atheromatous arteries from patients, autopsy cases and rabbits with atheromatosis, and umbilical vein grafts inserted in the carotid arteries of sheep, all was shown to produce increased amounts of thromboxane, compared to normal vessels. Platelets was probably not the source of Tx since these cells were not found in many of the vascular walls microscopically and sheep platelets are known to produce insignificant amounts of Tx. Leukocytes were often found in the walls of these vessels, and activated leukocytes may e.g. by release of active oxidant species, stimulate endothelial cells to produce an increased amount of thromboxane. This increased production of thromboxane may be of importance for induction of arterial thrombosis, which was prevented experimentally by inhibitors of thromboxane synthetase but may be of less importance for the development of venous thrombosis. The findings suggest that in prevention of arterial thrombosis, thromboxane synthesis should be blocked not only in platelets but also in the vascular wall,which requires higjner doses of inhibitor.

Resumen
Coronary and peripheral artery diseases are a leading cause of morbidity and mortality in developed countries. For severe cases, surgical intervention to bypass the disease using autologous vessels continues to be the preferred choice of treatment. These bypass vessels are typically obtained from the venous vasculature. Despite the superior long-term patency of veins over synthetic grafts, one-year failure rates approach 30–40% in both the coronary and peripheral systems [1–2]. Still, bypass surgery remains the recommended therapy for most persons with severe arterial blockages [3]. As the number of bypass procedures increase and patients receiving bypasses live longer, improving the lifetime of bypass grafts is increasingly important.

Resumen
Abstract: The study aims to conduct a retrospective review of 27 cases of a congenital portosys-temic shunt in dogs from 2015 to 2023, providing insights into classification, clinical man-ifestations, diagnostics, anaesthesia, surgery, and perioperative care. Initiation of medi-cal therapy at least 14 days before surgery aims to alleviate clinical signs and mitigate anaesthesia and surgery risks, emphasising a low-protein diet and lactulose to trap am-monium ions in the intestinal lumen and was strictly followed in all patients. Changes in drug uptake, metabolism, and excretion should be considered when choosing an anaes-thesia protocol. All dogs, except one with absent portal vein, underwent cellophane placement, facilitating gradual shunt closure. All dogs recovered uneventfully from sur-gery without evidence of portal hypertension and showed clinical improvement after that. Keywords: Portosystemic shunts, dogs, cellophane attenuation, perioperative preparation

Resumen
Context: Primary central nervous system angeitis (APSNC) is a vasculitis confined to the central nervous system (CNS). Its incidence rate is 2.4 cases per 1,000,000 person-years. It affects predominantly small and medium sized arteries of the cerebral parenchyma, spinal cord and leptomeninges. The most common manifestations are headache, cognitive impairment, stroke and transient ischemic attack. The fact that it results in multifocal inflammation of the arteries and veins can lead to ischemic or hemorrhagic infarctions in multiple vascular territories, more common in the subcortical white matter. Case report: A woman with a past of epilepsy and headache present to us with acute intraparenchymal hemorrhagic stroke, after extensive investigation, arrived at the presumed diagnosis of APSNC. Conclusion:Tests such as MRI and arteriography have low sensitivity and specificity for APSNC and brain biopsy is still the gold standard method for diagnosis, but in practice it is performed in less than half of the cases in clinical practice, this is due to several factors. Next, it is important to note that the biopsy efficiency is around 53-74% in unselected areas, reaching 80% if the site is selected affected by non-invasive exams. The literature specifies brain biopsy as a procedure with relatively low morbidity and mortality, however, it was not performed in more than a half of cases.

Resumen
The following research aims to elaborate and evaluate a categorical method of systematization, the thus called digital affective cartographies. In the context of 21st century smart cities, technological devices enable urban capture and processing of a large amount of dynamic data, which can facilitate the understanding of dynamic data from digital maps. The categorical method was organized into four system layers: (a) dynamicity (dynamic x static), (b) responsiveness (immediate x non-immediate), (c) implementation domain (hard x soft) and (d) affective aspect (quantitative x qualitative). For the evaluation of this and to test its applicability, it was applied in four cases of the Senseable City Lab: (1) City Veins (several cities), (2) City Ways (San Francisco and Boston), (3) Unparking (Singapore) and ( 4 ) Copenhagen in real time (Copenhagen). Keywords: Affective cartography, Affect, Map categorization, Smart City. Esta pesquisa tem como objetivo a elaboração e avaliação de um método categórico de sistematização das aqui chamadas cartografias afetivas digitais. No contexto das cidades inteligentes do século XXI, dispositivos tecnológicos possibilitam a captação e processamento de uma grande quantidade de dados, os quais podem facilitar a compreensão das dinâmicas urbanas através dos mapas digitais. O método categórico de sistematização foi organizado em quatro camadas: (a) dinamicidade (dinâmica x estática), (b) responsividade (imediata x não imediata), (c) domínio de implementação (hard x soft) e (d) vertente afetiva (quantitativa x qualitativa). Para a avaliação deste método e testar sua aplicabilidade foi aplicado em quatro casos da Senseable City Lab: (1) City Veins (diversas cidades), (2) City Ways (São Francisco e Boston), (3) Unparking (Cingapura) e (4) Real time Copenhagen (Copenhagen).
