Autogenous jugular veins and Dacron grafts of different porosities were implanted as short bypass grafts around ligated femoral arteries in the dog. Patency rates for periods up to eight months were: vein, 79 per cent; DeBakey Dacron (lowest porosity), 39 per cent; Wesolowski Weavenit (imtermediate porosity), 56 per cent; high porosity Dacron, 8 per cent. The failure of sixteen of the twenty-four high porosity grafts was related to perigraft hematomas that occurred two to seven days after operation and later thrombosis. The higher the porosity of the graft, the better the healing pattern as evidenced by fibrous bonding of the inner and outer linings of the grafts through the interstices. In the spectrum of grafts with increasing porosity there is apparently an optimal porosity beyond which late bleeding counterbalances the better healing properties of the higher porosity graft.
将自体颈静脉和不同孔隙率的涤纶移植物作为短旁路移植物植入狗结扎的股动脉周围。长达八个月的通畅率为：静脉，79%；德巴基涤纶（孔隙率最低），39%；韦索洛夫斯基编织物（孔隙率中等），56%；高孔隙率涤纶，8%。24个高孔隙率移植物中有16个失败与术后2至7天出现的移植物周围血肿及随后的血栓形成有关。移植物的孔隙率越高，愈合模式越好，这表现为移植物的内层和外层通过孔隙形成纤维性结合。在孔隙率不断增加的移植物范围内，显然存在一个最佳孔隙率，超过此孔隙率，后期出血会抵消高孔隙率移植物更好的愈合特性。
