本文对大隐静脉移植支再狭窄的病人采用球囊成形、旋切及支架治疗,以血管内超声评价各种介入技术的效果并与冠状动脉造影进行对比。方法:18例冠状动脉搭桥术后病人,经造影证实大隐静脉移植支有明显狭窄。其中大隐静脉连接于左前降支6例,左回旋支4例,右冠状动脉6例,对角支2例。采用球囊成形术7例;斑块旋切8例;支架留置3例。
This article on the saphenous vein graft stenosis patients using balloon forming, rotation and stent treatment, intravascular ultrasound to evaluate the effect of various interventional techniques and compared with coronary angiography. Methods: 18 cases of coronary artery bypass graft surgery patients, confirmed by angiography saphenous vein transplantation with obvious stenosis. The saphenous vein connected to the left anterior descending branch in 6 cases, left circumflex branch in 4 cases, right coronary artery in 6 cases, diagonal branch in 2 cases. Balloon angioplasty in 7 cases; plaque peeling in 8 cases; stent indwelling in 3 cases.
