Tratamento Endovascular dos Aneurismas de Artéria Poplítea

Background: With the recent advances in endovascular techniques and the emergence of more flexible endoprosthesis, the treatment of popliteal artery aneurysms has become more frequent. The objective of this study was to evaluate the short and mid-term clinical outcomes of the treatment of popliteal artery aneurysms with the use of a flexible endoprosthesis. Methods: Retrospective longitudinal study conducted in two sites from January of 2011 to February of 2014. Populational characteristics, procedure-related data, and radiologic imaging were evaluated at a mean follow-up of 1 year. Morbidity and mortality rates, complication rates, and stent patency rates were obtained. Results: A total of 13 male patients, mean age 66 ± 9 years, were submitted to popliteal artery aneurysm treatment in 15 limbs. Run-off vessel evaluation showed that most patients had at least two patent arteries in the legs (92.3%). Stents were implanted in the middle segment in 57.1% and in the distal segment of the popliteal artery in 42.9% of the procedures. Target lesion revascularization was achieved in all of the cases and two stents were required in four limbs. Seventeen ViabahnTM and two MultilayerTM stents were used. During the 12-month follow-up there were no stent fractures. The primary patency rate was 53.3% and limb salvage rate was 100%. Conclusions: Endovascular treatment of popliteal artery aneurysm was shown to be effective in the mid-term follow-up.
