During the period November 1979 to October 1984, 19 patients at our institution underwent balloon angioplasty of partial or complete obstruction of aortocoronary artery saphenous vein bypass grafts. The procedures were performed a mean of 38 months after a coronary bypass operation to relieve recurrent angina of at least class 2 in the Canadian Cardiovascular Association functional classification. Graft angioplasty was successful in 16 of the 19 patients, and the location of the lesion (in the origin, body, or distal insertion of the graft) did not seem to be an important factor in achieving a successful result. At a mean follow-up interval of 20 months (range, 1 to 40 months), 14 patients had symptomatic improvement. Two patients required late repeat operation and four had repeat angioplasty because of restenosis. Our experience supports the use of balloon angioplasty in selected patients with bypass graft stenosis, but restenosis remains a substantial problem.
在1979年11月至1984年10月期间，我院19例患者接受了主动脉冠状动脉大隐静脉旁路移植血管部分或完全阻塞的球囊血管成形术。这些手术平均在冠状动脉旁路手术后38个月进行，以缓解加拿大心血管协会功能分级中至少2级的复发性心绞痛。19例患者中有16例移植血管血管成形术成功，病变部位（在移植血管的起始部、体部或远端插入处）似乎不是取得成功结果的重要因素。平均随访间隔20个月（范围1至40个月），14例患者症状改善。2例患者需要后期再次手术，4例因再狭窄接受再次血管成形术。我们的经验支持对选定的旁路移植血管狭窄患者使用球囊血管成形术，但再狭窄仍然是一个重大问题。
