  • Title: Iliac angioplasty as a prelude to distal arterial bypass.
    Author: Katz SG, Kohl RD, Yellin A.
    Journal: J Am Coll Surg; 1994 Nov; 179(5):577-82. PubMed ID: 7952462.
    Abstract:
    BACKGROUND: Patients with limb ischemia and diffuse aortoiliac or combined aortoiliac and femoropopliteal disease present as a difficult problem for surgeons. This study was done to determine whether or not angioplasty can be successfully used as a prelude to distal bypass in patients with multilevel arterial occlusive disease. STUDY DESIGN: This is a retrospective review of an entire hospital experience with iliac angioplasty used as a prelude to distal arterial bypass. Kaplan-Meier life table analysis was performed and comparisons were made using log rank method. RESULTS: During a six year period, 37 patients underwent percutaneous iliac angioplasty before distal arterial reconstruction. Subsequent arterial reconstructions included femorofemoral bypass in nine patients, femoropopliteal bypass in 25 patients, femorotibial bypass in two patients, and common femoral endarterectomy in the remaining patient. The primary graft patency rate was 81 percent at five years. The overall success of iliac angioplasty was 76 percent at five years. Limb salvage was achieved in 78 percent of the patients with threatened extremities, and there was no perioperative mortality. CONCLUSIONS: Iliac angioplasty can successfully be used as a prelude to distal arterial bypass in patients with multilevel disease. The rate of angioplasty failure is low and grafts often remain patent in the face of early hemodynamic inflow failure, allowing salvage by operation or repeat dilatation. Close follow-up evaluation will allow early detection and appropriate correction of changes in inflow hemodynamics that occur before graft closure.
