[Endovascular treatment of popliteal artery aneurysm in a clinical analysis of 9 cases].

OBJECTIVE: To evaluate the efficacy of endovascular repair of popliteal artery aneurysm (PAA) and to summarize the clinical experience and lessons.

METHODS: A clinical data of 9 PAA cases (males 8, females 1, age range 55-84) undergoing endovascular repair from October 2006 to December 2014 at Zhongshan Hospital Fudan University were retrospectively analyzed. CT angiography was made in all of the 9 cases preoperatively, and 10 PAA were included in the analysis. Of the 9 cases, 6 cases were symptomatic. The mean diameter of PAA was 3.9 cm (range, 2.1-8.2).

RESULTS: The technique successful rate of endovascular repair was 10/10. The preoperative complications were 2/10, including one case suffered hematoma in the arterial puncture site and 1 case with distal artery embolization. The mean follow-up was 33 months (range, 3-87). During the follow-up, 2 cases received the secondary intervention and drug thrombolysis because of the stent distal thrombosis. The stent-graft primary patency at 1 year was 78.8% (95% CI: 48%-91%). One case suffered stent fracture, and one case died of brainstem hemorrhage 15 months post endovascular repair of PAA.

CONCLUSIONS: Endovascular treatment of PAA is safe and effective in perioperative and midterm follow-up. However, individual endovascular strategy and postoperative complications in the long-term follow-up should be payed more attention.
