Treatment of Complex Arteriosclerotic Lesions with Nitinol Stents in the Superficial Femoral and Popliteal Arteries: A Midterm Follow-up¹

¹ From the Department of Radiology, General Hospital, Grieskirchnerstrasse 42, A-4600 Wels, Austria (H.F.L., M.K.); Department of Radiology, St Franziskus Hospital, Grieskirchen, Austria (H.H., H.R.); and Department of Medical Statistics, University of Vienna, Austria (A.A.). Received January 10, 2001; revision requested March 2; revision received June 18; accepted July 16. Address correspondence to H.F.L. (e-mail: lugmayr.hf@aon.at).

PURPOSE: To evaluate the effectiveness of nitinol stents in patients with short, complex lesions in the superficial femoral and popliteal arteries and to assess midterm results.

MATERIALS AND METHODS: Self-expandable nitinol stents were implanted in 54 extremities in 44 patients to treat complex stenoses (n = 32) and occlusions (n = 22) in the superficial femoral and popliteal arteries. Follow-up was performed for 5–51 months to evaluate early thrombosis and midterm patency rates. Midterm patency rates were compared between the following: stenoses and occlusions, proximal and distal locations, good and poor runoff, and diabetic patients and nondiabetic patients. All patients underwent clinical investigation and color Doppler sonography after 1 month and 6 months and at 6-month intervals thereafter. If restenosis or stent thrombosis was suspected, intraarterial digital subtraction angiography of the superficial and popliteal arteries was performed.

RESULTS: Percutaneous stent implantation was successful in all patients. The mean duration of follow-up was 27 months (range, 5–51 months). No thrombotic occlusion occurred within the first 4 weeks after stent implantation. The primary 3-year patency rate was 76%, and the secondary patency rate was 87%. Three-year primary patency rates were 65% for diabetic patients and 82% for nondiabetic patients.

CONCLUSION: In patients with short, complex stenoses and occlusions, implantation of nitinol stents may have a positive impact on midterm results.
