The vascular prosthesis without pseudointima prepared by antithrombogenic phospholipid polymer.

On the luminal surface of the common synthetic vascular prostheses, blood coagulation can occur and a thrombus membrane is formed when blood flow passes through it. The thrombus membrane should be organized according to the wound healing process and it becomes a pseudointima which could serve as a blood conduit. However, the small-diameter vascular prosthesis may be quickly occluded by the initial thrombus.
