Purpose: Conventional balloon angioplasty of anastomotic stenosis following bypass surgery is insufficient at mid- and long-term. However, short-term results with cutting balloon angioplasty (CBA) are satisfactory. The purpose of this study is to determine the long-term results using this technique. Materials and methods. Between January 2002 and January 2006, all patients with anastomotic stenosis more than one month after bypass surgery, shorter than 2 cm and>50%, were referred without randomisation to CBA.
Results: A total of 19 patients with mean age of 63.5 years (55-82 years), 14 males and 5 females, were included. Twenty stenoses (femoral n=15, popliteal n=4 and calf n=1) managed with CBA affected 17 infrainguinal and 2 suprainguinal bypasses. One patient had anastomotic stenoses at both extremities. The rate of technical success aws 100%. Mean follow-up was 32 months (12-42). Three deaths occurred during follow-up. One patient presented with restenosis at 3 months, successfully treated with repeat CBA. No thrombosis or infection was observed.
Conclusion: The results with CBA appear persistent and compete favorably with results from surgical repair. A randomized trial would be necessary to confirm these results.
