Percutaneous transluminal coronary angioplasty (PTCA) has been used clinically for 8 years and is becoming widely accepted in the treatment of atherosclerotic coronary artery disease. Since the long-term effects of the procedure are unknown, the rate of restenosis following the procedure, approximately 30%, is of major concern. We briefly review the current status of PTCA and the effect of angioplasty on the vessel wall and discuss proposed mechanisms of recurrent stenosis.
经皮腔内冠状动脉成形术(PTCA)已临床应用8年,在治疗动脉粥样硬化性冠状动脉疾病方面正被广泛接受。由于该手术的长期效果尚不清楚,术后再狭窄率约为30%,这是主要关注的问题。我们简要回顾PTCA的现状以及血管成形术对血管壁的影响,并讨论复发性狭窄的可能机制。
