ABSTRACT
The aim of this retrospective study was to evaluate the immediate and long-term results of various treatments for patients with a primary lesion of intra-stent restenosis (ISR). The study included 214 patients (233 endoprostheses, site of a primary ISR), with an average age of 61+/-11 years. These patients had received one of the following treatments balloon angioplasty alone (101 patients), implantation of a second endoprosthesis (32 patients), medical treatment (65 patients), or revascularisation surgery with aorto-coronary bypass (16 patients). After retrospective analysis of the initial data, clinical follow-up was studied for all patients, and severe cardiac events were recorded. The immediate treatment of the ISR with angioplasty or bypass had an initial success rate of 100%. At the end of follow up (26+/-1.8 months) for the series as a whole, 9 patients (4.1%) had died, 7 (3.2%) had suffered a myocardial infarction, and 22 (10.3%) had had to undergo a secondary revascularisation procedure. 111 (52%) patients had angiographic follow up. A second ISR was noted in 43 cases (39%). The type of treatment provided was not a predictive factor for the occurrence of a severe cardiac event. In conclusion, whatever treatment of ISR is used, the immediate result is satisfactory. The rate of severe cardiac events is acceptable and in 10.3% of cases necessitates a secondary revascularisation procedure within 2 years. The very promising recent development of new active endoprostheses could alter the management of coronary patients in the years to come.
