The Interposition Arteriovenous Loop Revisited

ABSTRACT

In clinical situations when both arterial and venous interposition vein grafts are mandatory, we invariably harvest a single graft of adequate length to create an initial arteriovenous loop. This concept deserves re-emphasis, as satisfactory recipient anastomoses can be achieved prior to bisecting the loop, with subsequent immediate donor tissue transfer. Concern for prolonged warm ischemia time is thereby minimized.
