A standard 40 mm arteriotomy was created in canine iliac and carotid arteries and then closed by either direct suture without a patch, with a vein patch or with a polytetrafluoroethylene patch (PTFE). The uptake of 111-Indium oxine labelled platelets at 2 hours after operation was compared between the groups. Arteriotomies closed with a PTFE patch demonstrated significantly greater platelet aggregation than those closed with a vein patch. Primary closure without a patch was associated with the least platelet uptake of all (PTFE versus vein patch, P less than 0.01; PTFE versus no patch, P less than 0.01; vein patch versus no patch, P less than 0.05). Light and electron microscopy confirmed the radioisotopic findings.
在犬的髂动脉和颈动脉上做一个标准的40毫米动脉切口,然后分别采用无补片直接缝合、静脉补片或聚四氟乙烯补片(PTFE)进行闭合。比较各组术后2小时111-铟喷曲肽标记血小板的摄取情况。与采用静脉补片闭合的动脉切口相比,采用PTFE补片闭合的动脉切口血小板聚集明显更多。无补片的一期闭合在所有情况中血小板摄取最少(PTFE与静脉补片相比,P<0.01;PTFE与无补片相比,P<0.01;静脉补片与无补片相比,P<0.05)。光镜和电镜检查证实了放射性同位素检查结果。
