Percutaneous transluminal coronary angioplasty (PTCA) has been used to treat patients with previous coronary artery bypass grafting (CABG). Seven patients with previous CABG underwent coronary artery or vein graft angioplasty following a recurrence of symptoms. Fifteen lesions were attempted in 7 patients. The primary angiographic success rate was 100%. The primary angiographic success rate was defined as reduction of a stenosis by at least 20% of the vessel diameter, leaving a stenosis of less than 60%. There were no complications following PTCA such as death or myocardial infarction. No patients were referred for urgent surgery. Three patients have undergone another PTCA after 3 months and remain well. All patients at follow-up continue to have improved symptoms. Our experience suggests that the patients with recurrence of coronary artery or bypass stenosis following CABG may be suitable for PTCA.
经皮腔内冠状动脉成形术（PTCA）已被用于治疗曾接受冠状动脉旁路移植术（CABG）的患者。7例曾接受CABG的患者在症状复发后接受了冠状动脉或静脉移植血管成形术。7例患者共尝试处理15处病变。初次血管造影成功率为100%。初次血管造影成功率定义为血管直径狭窄至少降低20%，残余狭窄小于60%。PTCA术后无死亡或心肌梗死等并发症。无患者被转诊进行急诊手术。3例患者在3个月后接受了再次PTCA，目前情况良好。所有随访患者的症状均持续改善。我们的经验表明，CABG后冠状动脉或旁路狭窄复发的患者可能适合PTCA。
