在694例尝试经皮腔内冠状动脉成形术以缓解症状性冠状动脉疾病的患者中，74例随后因症状性再狭窄接受了重复手术。55例患者（74%）再次扩张成功。初次手术和重复手术的初次成功率和严重并发症发生率相似。再次手术的并发症包括严重夹层（14%）、急性闭塞（7%）和紧急冠状动脉搭桥手术（12%）。平均随访113周（范围15-309周）后，33例患者（60%）无症状; 22例（40%）心绞痛复发。在我们看来，重复经皮腔内冠状动脉成形术的成功率、并发症发生率和长期结果与初次手术相似。
Of 694 patients in whom percutaneous transluminal coronary angioplasty was attempted for palliation of symptomatic coronary artery disease, 74 subsequently underwent a repeat procedure because of symptomatic restenosis. The repeat dilatation was successful in 55 patients (74%). The primary success rate and the incidence of major complications were similar for initial and repeat procedures. Complications of the repeat procedure included major dissection (14%), acute occlusion (7%) and emergency coronary bypass surgery (12%). After a mean follow-up period of 113 weeks (range, 15-309 weeks), 33 patients (60%) were asymptomatic; angina recurred in 22 (40%). In our hands, the success rate, complication rate, and long-term results of repeat percutaneous transluminal coronary angioplasty were similar to those associated with the initial procedure.
