Level 2: Duplex scanning of the left leg (May 1989) showed absence of the greater saphenous vein. The common femoral and profunda femoris veins were patent and competent. There was partial reca nalization of the superficial femoral and popliteal veins. The posterior tibial vein was also recanalized. No perforating veins were identified. Duplex scan Sep 1997: left superficial femoral and poplite...

Our studies were carried out on 8 male and 2 female baboons Papio anubis cadavers. We examined a total of 20 hind legs. The vessels of the hind leg were filled with coloured latex. Afterwards we prepared the superficial and deep veins and accompanying arteries. We paid attention to the location, diameter and the course of the long and short saphenous veins. We found many differences between the...

T Objective: Approximately 50% of aortocoronary saphenous vein grafts are occluded 10 years after coronary revascularization surgery. Intimal hyperplasia, a critical component in saphenous vein graft failure, is defined by vascular smooth muscle cell proliferation, which is mediated in part by subunits of heterotrimeric G proteins (G ) and downstream effectors such as mitogen-activated protein ...

The potassium channel blocker tetraethylammonium blocks the flow-induced increase in endothelial ICAM-1. We have investigated the subtype of potassium channel that modulates flow-induced increased expression of ICAM-1 on saphenous vein endothelium. Cultured human saphenous vein endothelial cells (HSVECs) or intact saphenous veins were perfused at fixed low and high flows in a laminar shear cham...

The safety and efficacy of temporary pericardial pacing wires have been accepted and their use is common after cardiac operations. Complications related to pacing wire removal are unusual but it can be serious and even catastrophic. We report an unusual case of bleeding due the laceration and rent created in the saphenous vein graft wall by the metallic tip of the pacing wire at the time of pac...

OBJECTIVES Saphenous nerve injury is the most common complication after surgical treatment of varicose veins. The aim of this study was to establish its frequency at great saphenous vein long stripping when four methods of surgery were applied. METHODS Eighty patients were divided into four groups depending on different stripping methods. Sensory transmission in saphenous nerve and sensory pe...
