Anastomotic Intimal Hyperplasia in vascular grafts

Abstract

Factors affecting anastomoic intimal hyperplasia (AIH) were analyzed, There were two types of AIH: (1) occured at the host artery for a length of 5mm segment from the suture line. This rare type of AIH is mainly caused by compliance mismatch. (2) occurred 2S a form of punnus hyperplasia due to undequate blood and hist compatibility of the vascular prosthesis, and were frequently observed in Biograft and e-PTFE. We conclude that development of a compound vascular prosthesis with basement membrene is necessary in order to prevent the AIH.
