Platelets labelled with Indium-111 were used to examine the in vivo thrombogenicity of different vascular grafts. The deposition of platelets in two partly different kinds of umbilical vein grafts, double velour Dacron grafts and double velour Dacron grafts with internal collagen was studied as a function of time. The grafts were inserted end to side in the femoral artery of pigs and then imaged for 120 minutes. Platelet distribution was also studied by in vitro static imaging. No difference was seen between the different umbilical vein grafts. The double velour grafts accumulated more platelets, the platelets mainly located in the midportion of the graft. The collagen-impregnated grafts occluded within 45 minutes.
用铟 - 111标记的血小板来检测不同血管移植物的体内血栓形成性。研究了两种部分不同类型的脐静脉移植物、双层丝绒涤纶移植物以及含内部胶原蛋白的双层丝绒涤纶移植物中血小板的沉积情况与时间的关系。将这些移植物端侧吻合到猪的股动脉中，然后进行120分钟的成像。还通过体外静态成像研究了血小板分布。不同的脐静脉移植物之间未见差异。双层丝绒移植物聚集了更多血小板，血小板主要位于移植物的中部。含胶原蛋白的移植物在45分钟内就发生了堵塞。
