Factors influencing postoperative vascular patency.

In summary, we have briefly examined the pathogenesis of arterial thrombosis, the importance of vessel wall injury and alteration of blood flow in this process, and finally the rationale for use of various agents in an attempt to promote postoperative vascular patency. At present, as in the past, the most important factor toward ensuring patency after arterial reconstruction is a technically perfect operation which allows vigorous inflow and runoff and rapid linear flow (25).
