The Use of Vascular Stents in the Treatment of Iliac Artery Occlusion.
To evaluate our experience of selective iliac artery stenting for total occlusions, a prospective observational study of 25 patients with an occluded iliac artery was designed to run from January 1996-May 1997. Exclusion criteria were an occlusion extended to the femoral artery, claudication Grade III or IV, according to the standards for reports dealing with lower extremity ischemia, and vascular (bypass) surgery in the past. Complete recanalization and selective stent placement was possible in all patients. No complications occurred. In one patient re-stenosis happened inside the stent after a year. Percutaneous reintervention was performed with success. The mean ankle-brachial pressure increased from 0.46 before the procedure to 0.95 after the procedure. After two years of follow-up, the mean ankle-brachial pressure is 0.93. The clinical stage improved by at least one grade to Grade 0 (Rutherford classification). The overall probability of patency for occluded iliac arteries in this study was 95% after two years. Recanalization, followed by percutaneous transluminal angioplasty (PTA) in the treatment of iliac artery occlusions, is our first choice of intervention, considering the absence of complication and satisfactory patency rates in patients with claudication Grade I or II.
