BACKGROUND: Fusiform or dolichoectatic intracranial aneurysms often cannot be managed with conventional surgical or endovascular techniques, and instead require trapping and revascularization techniques. On rare occasions in elderly patients, extracranial sites used for anastomosing the bypass have been previously repaired with synthetic vascular prostheses. This circumstance in an elderly subarachnoid ...
Tsui J C - - 2001
BACKGROUND: The saphenous vein is the most commonly used conduit for coronary artery bypass surgery, but 1-year occlusion rates as high as 30 per cent have been reported. In conventional surgery, considerable damage to the vein occurs during harvesting. The aim of this study was to compare endothelial integrity and ...
Oderich G S - - 2001
In situ lesser saphenous vein (LSV) graft has been advocated in cases where the greater saphenous vein is not available and the target arteries are confined to the lower leg. This is often the case of diabetic patients, whose occlusive disease pattern typically affects the tibioperoneal vessels, sparing the femoropopliteal ...
