摘要
本文报道5例不同类型复杂冠状动脉病变腔内成形术。对于位于血管分叉处的病变,采用了双导丝技术;对于引起急性心肌梗塞的高度狭窄血管采用自灌注球囊扩张;对于完全闭塞且病变较长的血管,采用较硬的标准直头导引钢丝导入尔后逐段扩张的办法;对于术中出现的内膜剥离,采用了自灌注球囊导管行长时间低压修补。术后血管再通,残余狭窄为0～10％。因此,认为只要针对不同情况,采用不同方法,PTCA成功率可望提高。
Percutaneous transluminal coronary angiolasty(PTCA)was performed in 5 different kinds of complex coronary artery disease. Bi-quidwires technique was used to the patient whose lesion was located at the bifurcation of vessel and autoperfusion technique to the patient with severe coronary artery stenosis resulting in acute myocardial infarction. The total and longer coronary occlusion was progressively dilated by balloon catheter with the harder quidwire (Hi-Torque standard)crossing the occlusion. The coronary dissection was repaired with autoperfussion balloon catheter under lower pressure and longer time. All procedures were successful in PTCA. The results showed that an optimal PTCA efficacy would be obtained by using different methods according to different situations.
