Technical Factors in Enhanced Patency Rates In Aorto Coronary

摘要

Coronary artery bypass grafting with autologous saphenous vein has a well established therapeutic role for both relief of symptoms and prolongation of life’.It is reasonable to suggest that methods of harvesting that produce vein with undamaged endothelium and media would enhance patency rates.The choice of size of the needle is more important than the size of the sutur using the averting technique of anastomosis. Averting technique also voids exposure of collagen of graft and coronary artery wall which promote platelet activation and fibrin attachment ’4”5 .Though a proportion of graft failure is attributable to poor run off due to progression of native coronary arterial disease, attention to the above factors will undoubtedly prolong graft patency by preventing both early and late graft occlusion by thrombosis or acce1erated intimal proliferation complicated by artheroma. These factors are avoidable and careful detail at each step is necessary. This may well reduce the need for redo-coronary artery bypass grafting.
