Popliteal artery aneurysms (PAAs) are the most frequent peripheral aneurysm with a significant morbidity if left untreated. Open surgical technique is still considered the gold standard; however the revolution in endovascular repair has proven to be a valid alternative option in selected patients. The role of endovascular treatment in PAA is still considered in its infancy. In addition, the indications for use of endovascular stents as compared to standard open surgery have not yet been fully defined and more studies are warranted to characterize the durability of this technique. This article describes the general principles of the natural history, clinical presentation, and long-term limb salvage and survival outcomes for patients with such aneurysms. It also details the features and results for the devices in current use and highlights the current consensus in the management of PAA.
