title: [Angioplasty in patients already treated with aortocoronary bypass: immediate and short-term results].
abstract: Percutaneous transluminal coronary angioplasty (PTCA) is performed in patients with prior aortocoronary bypass grafting (CABG) with good results in native vessels and in the coronary graft anastomoses, but with high percentage of restenosis in the body and in the proximal portion of the grafts. The use of intracoronary stents is now spreading, their implantation can improve the immediate outcome and may decrease the incidence of restenosis, mostly in the body of the graft. In order to evaluate PTCA in CABG patients as to numbers and short-term results, the data regarding the year 1993 of 10 Italian Centers are presented. In these Centers 3,519 PTCA were performed, 233 (6.6%) of which on CABG patients. PTCA has been performed in native vessels in 136 patients and in CABG in 126 patients, with 29 patients treated in native vessels as well as in CABG. An angiographic and clinical success was obtained in 215 patients (92%). A major complication occurred in 11 (4.7%) patients with 8 (3.4%) myocardial infarctions, and 3 (1.3%) deaths. Forty-five (19.3%) stents were implanted with considerable differences among the Centers. One hundred seventy-three patients were followed up for 6 months: 110 (63.6%) were asymptomatic and 57 (32.9%) had complained angina; 27 (15.6%) had a second PTCA and 6 (3.5%) had CABG surgery; 1 patient (0.6%) suffered a myocardial infarction and 7 (4%) died (3 due to CABG reinterventions). To evaluate the long-term follow-up, data regarding 58 patients submitted to PTCA in the Institute of Cardiology of Bologna since 1985 to 1993 are showed, with a 3-year follow-up (36 +/- 26 months).(ABSTRACT TRUNCATED AT 250 WORDS)
