Background: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysms. Although rare and often asymptomatic, there is a significant risk of thrombosis, embolism, and limb loss. The aim of this study was to evaluate the eligibility for endovascular repair of patients treated for symptomatic and asymptomatic PAAs in accordance with the instructions for use (IFU). Methods: All patients treated for PAA with open surgical repair between the years 2010 and 2017 were analyzed if suitable for endovascular treatment. Preoperative imaging was reviewed for applicability with an interventional radiologist and 2 vascular surgeons. Evaluation was performed in accordance with the following criteria adopted from the IFU of the Gore ® Viabahn stent graft: at least a single-vessel tibial runoff, proximal and distal landing zone more than 2 cm, no large difference in vessel diameter proximal and distal to the aneurysm, no overstenting of significant collaterals necessary, and no inadequate kinking of the artery. The patients were classified in 3 categories: the patient was eligible, endovascular treatment was feasible, and endovascular treatment was not appropriate. Results: 51 patients with 61 symptomatic and asymptomatic PAAs were identified. Forty-five cases were asymptomatic, 11 cases showed clinical symptoms such as claudication, and in 5 cases, the patients presented with acute ischemia. Twenty-four patients were eligible for endovascular intervention, 14 cases were feasible, and in 23 cases, it was not appropriate in accordance with the IFU. Conclusions: In this study, more than one-third of the patients with PAA were not eligible for endovascular treatment in accordance with the IFU and another 23 % showed substantial reasons against endovascular treatment. These data suggest that endovascular repair remains a treatment option for selected patients only. Cross-sectional imaging is mandatory for procedure selection.
