background: anticoagulation therapy is a routine treatment in patients with hemorrhagic cerebral venous thrombosis (cvt). however, fear of hemorrhagic complications and deterioration course following anticoagulation often disturbs the responsible physician. methods: this was a prospective observational study on consecutive cvt patients with hemorrhagic venous infarction or subarachnoid hemorrha...

OBJECTIVES Laparoscopic donor nephrectomy is now a commonly performed procedure in most of renal transplantation centers. However, the suitability of laparoscopy for donors with abnormal venous anatomy is still a subject of debate. MATERIALS AND METHODS Between August 2007 and August 2014, 243 laparoscopic donor nephrectomies were performed in our institution. All donors were evaluated with p...

OBJECTIVE In cases of aortic valve replacement, the downstream flow profile and turbulence in the ascending aorta differ according to the prosthetic aortic valve implanted. The objective of this work is to study the influence of prosthetic valve type on the flow in the bypass grafts implanted to the ascending aorta in cases of concomitant aortic valve replacement and coronary artery bypass. M...

the goal of this study was to define the normal range of diameter in the deep vein of the lower limb and to compare this range with diameter of the veins with acute thrombosis and of veins with chronic thrombosis by using color doppler sonography. the study was cross sectional. the vein diameter and vein to artery ratio in different levels were measured and the following results were obtained. ...

The biosynthesis of extracellular matrix proteins by primary cultures of endothelial cells from human umbilical vein, and by clones from a murine hemangioendothelioma, was studied and compared to that reported for endothelium cultured from other sources. Umbilical vein endothelial cells secreted two glycoproteins-fibronectin and thrombospondin-which comprise the major proportion of the protein ...

PURPOSE To assess the role of multislice CT angiography in the evaluation of arterial, hepatic and portal venous variations in potential right lobe donors. MATERIALS AND METHODS Fifty-two potential liver donors (28 females, 24 males), underwent CT angiography in the arterial and portal venous phases with an eight-row CT scanner. Two- and three-dimensional images were obtained from 1.25-mm-thi...

AIMS Cathepsin S (Cat S) is a potent lysosomal protease that is secreted into the extracellular space and has been implicated in elastin and collagen degradation in diseases such as atherosclerosis. Elastin degradation plays an important role in vascular remodelling. However, the mechanism by which Cat regulates this process and its contribution to vein graft remodelling remains unclear. METH...

OBJECTIVES Analyze the anatomic variations of the testicular veins in human cadavers and fetuses. MATERIALS AND METHODS One hundred male adult cadavers and 24 fetuses were studied. Four anatomic aspects were considered: 1) Number of testicular veins, 2) The local of vein termination, 3) Type and number of collaterals present and 4) Testicular vein termination angle. RESULTS Cadavers - Right...
