Long-Term Follow-up After Peripheral and Coronary Angioplasty in Patients Undergoing Both Types of Procedure

Abstract

Restenosis rates after peripheral and coronary angioplasties have been assessed only in patients who had either peripheral angioplasty or coronary angioplasty but never in patients who had both types. Among the 6364 angioplasties performed in the authors' institution since 1980, they studied 38 patients (36 men, 2 women, mean age fifty-five years, range thirty-four to seventy-seven) who had both peripheral and coronary angio plasty. The peripheral angioplasties were most often performed on iliac artery stenoses. They were performed before coronary angioplasty in 22 patients (58%) and after coronary angioplasty in 16 patients (42%). The follow-up after peripheral angioplasty was based on clinical data; ultrasound investigation was performed when the result of the clinical follow-up was poor (maximal walking distance lower than 500 meters). Follow- up after coronary angioplasty was assessed by a systematic coronary angiography at six months and with long-term clinical follow-up. The mean durations of the follow-up after peripheral or coronary angioplasty were not significantly different (respectively fifty-six ±eleven and forty-two ±nine months [mean ±2 SEM]). No patient was lost to clinical follow-up; 17 (45%) ultrasound investigations, 12 (32%) peripheral angiographies, and 34 (89%) coronary angiographies were performed. The restenosis rate after peripheral angioplasty was 18% and that after coronary angioplasty was 34%. These rates are similar to the classic rates observed in the literature. In conclusion, as reported for either procedure alone, the restenosis rates after peripheral angioplasty and after coronary angioplasty are different when assessed in patients who undergo both types of angioplasty.
