Abstract

• Eighy-nine endovascular procedures were performed during a 1-year period. Techniques included balloon angioplasty (n=50), laser-assisted balloon angioplasty (n=32), and atherectomy (n = 7). Indications were claudication (65.2%), critical ischemia (30.3%), and failing bypass (4.5%). Preoperative evaluation included a history and physical examination, segmental limb pressures, and color duplex ultrasonography. Postoperative surveillance consisted of a history and physical examination, ankle-arm indexes, and color duplex examinations at 1-week, 1-month, and then 3-month intervals. All levels of aortoiliac and infrainguinal disease were treated. Immediate technical success rate was 89.8%. Recurrence rates by life-table analysis reveal a 9-month patency rate of 45.4%. Early results of this prospective study indicate that endovascular procedures are subject to significant restenosis rates. Restraint is advised concerning general acceptance of endovascular procedures pending critical study.
