Development of small-diameter vascular graft composed of antithrombogenic phospholipid polymer

经mpc包被和未包被ePTFE移植的颈动脉或股动脉绕道1周后的通畅率分别为9/37（24%）和14/37(38%)；2周后为4/37（11%）和6/37(15%)；4周后为3/37（8%）和3/37（8%）。根据组织学检查，血栓附着在宿主动脉的切边上。与未包被的移植物相比，包被的移植物吻合口和表面的内膜增生无明显变化。

The patency rates of carotid or femoral arterial bypass with MPC-coated and noncoated ePTFE grafts were 9/37(24%) and 14/37(38%) after one week ; 4/37(11%) and 6/37(15%) after two weeks ; and 3/37(8%) and 3/37(8%) after four weeks. Based on a histological examination, the thrombus was attached to the cut edges of the host artery. Intimal hyperplasia at the anastomosis and the surface of MPC-coated grafts was not changed remarkably compared with noncoated grafts.
