Development of endothelium-denuded human umbilical veins as living scaffolds for tissue-engineered small-calibre vascular grafts.
Tissue-engineered small-calibre vessel grafts may help to alleviate the lack of graft material for coronary and peripheral bypass grafting in an increasing number of patients. This study explored the use of endothelium-denuded human umbilical veins (HUVs) as scaffolds for vascular tissue engineering in a perfusion bioreactor. Vessel diameter (1.2 ± 0.4 mm), wall thickness (0.38 ± 0.09 mm), unia...
متن کاملNOTES Current Status of Cryopreserved Veins as Arterial Replacement Grafts: Results Are Better Than You Think
lthough the autogenous vein has proven itself to be the preferred conduit for infrainguinal revascularization, the ever increasing age and complexity of patients with arterial occlusive disease has brought about clinical scenarios where autogenous vein is not available and an alternative conduit must be found. Given the absence of reliable options for infrageniculate bypass when suitable autoge...
متن کاملAccessory and great saphenous veins as coronary artery bypass conduits.
Anatomic, histologic and ultrasound studies demonstrate two distinct types of longitudinal veins in the lower extremities. The great saphenous vein is deep to the saphenous fascia. Accessory saphenous veins are superficial to this layer, have thin walls with diminished muscle cells and elastic fibers. Vein characteristics may affect long-term graft patency. This study assesses the incidence of ...
متن کاملDown-regulation of endothelin B receptors in autogenous saphenous veins grafted into the arterial circulation.
OBJECTIVES It has been postulated that endothelin (ET) might be involved in the development of atherosclerotic vascular lesions. The present study was done to characterize changes in the contractility and ET receptor subtypes in the autogenous saphenous vein graft (VG). METHODS The rabbit saphenous vein (SV) was grafted into the ipsilateral femoral artery (FA), and at 4 weeks after the operat...
متن کاملCephalic veins in coronary artery bypass surgery.
Various alternative conduits for aortocoronary bypass grafting have been suggested when the saphenous vein quality is inadequate. During a 10-year period we have used the cephalic vein in 39 patients. Eighteen entered an angiographic follow-up study. A total of 31 arm vein grafts were used with 43 distal anastomoses. When calculating patency by number of patent distal anastomoses, this was 46% ...
