BACKGROUND Accelerated atherosclerosis is the main cause of late aortocoronary vein graft failure. We aimed to develop a large animal model for the study of pathogenesis and treatment of vein graft atherosclerosis. METHODS An autologous reversed jugular vein graft was inserted end-to-end into the transected common carotid artery of ten hypercholesteroemic minipigs. The vein grafts were invest...

-Vein graft intimal hyperplasia, due to smooth muscle cell (SMC) proliferation, remains a limiting factor in long-term vein graft patency. Increased superoxide production regulates SMC mitogenesis and contributes to reduced NO bioactivity in systemic models of vascular disease. We compared superoxide production in experimental venous bypass grafts with ungrafted veins and determined its enzymat...

The report is about 4 clinical observations that demonstrate advanced capabilities of surgical treatment leiomyosarcoma the inferior vena cava and its main tributaries (gonadal, common iliac, renal veins). examples present variants vascular reconstructions in stages, namely, alloprosthesis infrarenal segment bifurcated aortoiliac alloprosthetics. article also considers technique «kidney-preserv...

Introduction: cerebral vein thrombosis is a rare complication of nephrotic syndrome (NS).We report a known case of NS with hemorrhagic thrombosis. Case report: A boy with previous history of NS was admitted with headache and decrease of level of consciousness and his brain images were revealed hemorrhagic thrombosis Conclusions: cerebral vein thrombosis must be considered in patients with...

PURPOSE To examine the incidence and appearance of the communicating vein between the left renal vein (LRV) and the left ascending lumbar vein (LALV) on abdominal CT. MATERIALS AND METHODS We reviewed the appearance of the communicating vein on contrast-enhanced CT obtained by multidetector-row CT (MDCT) scanner. One hundred patients without known abnormality in this region were randomly chos...

The cephalic vein, defined as the vein originating in the radial end of the dorsal venous arch, crosses superficial to the anatomical snuffbox and travels upward along the anterior border of the brachioradialis muscle in the forearm [1,2]. It ascends lateral to biceps and between pectoralis major and deltoid muscles, and passes through the infraclavicular fossa, and drains into the axillary vei...
