Endovascular treatment of popliteal artery aneurysms: preliminary results

Popliteal artery aneurysms (PAAs) are a rare condition with an incidence < 0.1%. The objective of this study was to evaluate the effectiveness of endovascular treatment of PAA with a covered stent-graft. Between January 2009 and July 2010, ten patients (nine men and one woman, mean age 69 +/- 12 years) with PAA were treated by endovascular placement of a heparin-coated stent-graft. All procedures were evaluated in terms of technical success, patency at 1, 6 and 12 months as assessed by colour Doppler ultrasound, complications, procedure duration and length of postoperative hospital stay. We obtained 100% technical success, with no peri- or postprocedural complications. Average duration of the procedure was 40 min, and mean hospital stay was 3 days. Primary and secondary patency rates at 1, 6 and 12 months were 100% and 100%, 90% and 100%, and 90% and 100%, respectively. Only one case of endoleak occurred. In keeping with the literature, our study demonstrates the effectiveness of endovascular repair of PAA, with short- and mid-term patency rates comparable to those of open surgery. Larger series and longer follow-up periods are needed to confirm these preliminary results.
