1. Vascular Spectrum of Imaging Findings in COVID-19: Ischemic, Hemorrhagic, and Thromboembolic Complications
Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can

2. Tea Grape Reduces Abdominal Aortic Occlusion-Induced Lung Injury
Abstract Introduction: Ischemia-associated mortality caused by aortic cross-clamps, as in ruptured abdominal aorta aneurysm surgeries, and reperfusion following their removal represent some of the main emergency conditions in cardiovascular surgery. The purpose of our study was to examine the potential protective effect of tea grape against aortic occlusion

3. Superior vena cava syndrome: endovascular management
Resumo Contexto O tratamento da síndrome da veia cava superior (SVCS) visa aliviar, rapidamente, os sintomas desconfortáveis. Os resultados das abordagens convencionais nem sempre são tão rápidos quanto os do tratamento endovascular com colocação de stent. Objetivos Relatar a experiência de um Serviço de Cirurgia Vascular e Endovascular de hospita

4. Vascular sclerosing effects of bleomycin on cutaneous veins: a pharmacopathologic study on experimental animals
Abstract: Background: Varicose veins and the complications of venous disease are common disorders in humans. Objective: To study the effects of bleomycin as a potential new sclerosing agent and its adverse events in treating varicose veins. Methods: Bleomycin-loaded liposomes 0.1ml was injected in the dorsal ear veins of white New Zealand rabbits. Sodium

5. Effects of experimental pulmonary hemodynamic overload on cardiovascular system and pulmonary structural and function / Efeitos da sobrecarga hemodinâmica pulmonar experimental no sistema cardiovascular e na estrutura e função pulmonar
INTRODUCTION: The pulmonary hemodynamic overload (PHO) is associates to high mortality and morbidity clinical entities as: postpneumonectomy pulmonary edema, pulmonary thromboembolism, lung transplantation and physiological situations as physical exercise. Some pathophysiological aspects related to PHO are not elucidated. OBJECTIVES: To study pulmonary and c

6. Involvement of lymphatic system on lung inflammation induced by intestinal ischemia / reperfusion in rats. / Avaliação do envolvimento do sistema linfático na inflamação pulmonar decorrente de trauma esplâncnico.
In this study we investigated the role of lymphatic system on the mechanisms associated to the induction of lung inflammation afier intestinal I/R in rats. The hypothesis ofthe study was that upon intestinal I/R, inflammatory mediators are generated in the intestine and once drained by mesenteric lyrnphatic system interfere with the lung homeostasis contribu

7. Shy-Drager Syndrome : a functional protocol study of the Autonomic Nervous System in 3 cases / Sindrome de Shy-Drager : protocolo de estudo funcional do sistema nervoso autonomo em 3 casos clinicos
This study was motivated by the desire to better understand the autonomic functions in subjects clinically diagnosed as Shy-Drager syndrome. This syndrome was selected because it presents a disorder in the central autonomic structures of CNS. This degenerative disease represents a multiple disorders of CNS which include dysautonomia associated with pyramidal

8. Severe pulmonary vascular change in patients dying with right ventricular failure after heart transplantation.
Two patients died following heart transplantation from failure of the donor right ventricle. Histological examination of the lungs showed occlusion of pulmonary veins. A more reliable method is required to predict the outcome for potential heart transplant recipients with a "borderline" pulmonary vascular resistance.

10. Vascular occlusion and infarction in sickle cell crisis and the sickle chest syndrome.
A young adult with homozygous sickle cell anaemia (Hb SS) suffered a fatal sickle cell crisis complicated by the sickle chest syndrome. At necropsy multiple large infarcts of the lung, bone marrow, and pituitary gland were found. The large majority of pulmonary infarcts were not associated with either gross or microscopic vaso-occlusion. These findings are d

11. Lung and cardiac reflex actions on the tracheal vasculature in anaesthetized dogs.
1. With pentobarbitone-anaesthetized dogs, the cranial tracheal arteries have been independently perfused on both sides, to measure vascular resistance. Blood pressure and contractions of tracheal muscle were also measured. 2. Capsaicin was injected intravenously to stimulate lung C-fibre receptors. In breathing and in paralysed artificially ventilated dogs

12. Cardiac and peripheral circulatory responses to angiotension and vasopressin in dogs.
To determine the cardiac and peripheral circulatory responses to changes in afterload with angiotension and vasopressin, we increased mean aortic pressure 25% and 50% above control in splenectomized and ganglion-blocked dogs. We compared these responses to similar mechanical increases in aortic pressure produced by partial balloon occlusion of the descending
