PTCA is a new technique for the treatment of certain patients with coronary artery disease. It involves dilatation of stenotic segments of artery using a balloon catheter, and is carried out in cardiac catheterization laboratories. If successful, the need for coronary bypass surgery may be removed, although some patients with initially successful PTCA will come to surgery eventually. Successful PTCA is associated with relief of angina, improved angiographic appearances and coronary perfusion. The primary success rate is between 65% and 80%, and the restenosis rate approximately 25%. 80% of patients will be angina free one year after PTCA. In this paper the indications, contraindications, technology, results and complications are discussed.
经皮冠状动脉腔内血管成形术（PTCA）是治疗某些冠心病患者的一项新技术。它是使用球囊导管扩张动脉狭窄段，在心脏导管实验室进行。如果成功，可能无需进行冠状动脉搭桥手术，不过一些最初PTCA成功的患者最终仍可能需要手术。PTCA成功与心绞痛缓解、血管造影表现改善及冠状动脉灌注改善相关。主要成功率在65%至80%之间，再狭窄率约为25%。80%的患者在PTCA术后一年无心绞痛。本文讨论了其适应证、禁忌证、技术、结果及并发症。
