Percutaneous transfemoral endovascular repair of popliteal artery aneurysms.

Popliteal artery aneurysms are the hallmark of peripheral aneurysms, accounting for 70%, and are commonly bilateral in 50% to 75% of patients. The prevalence and incidence of popliteal artery aneurysms are not precisely known. The presence of a popliteal aneurysm is a marker of risk to limb and life because 33% to 43% are associated with an abdominal aortic aneurysm. Ligation and bypass reconstruction has long been the "gold standard" for the treatment of popliteal aneurysms. Recently, endoluminal repair with a percutaneously delivered stent-graft has become a valid alternative to open repair. In this study, we illustrate two cases of a total of four patients with popliteal artery aneurysms treated with percutaneous stent graft placement and discuss overall management of these aneurysms. The other two patients had a successful early outcome (30 days), but long-term follow-up is still lacking.
