Femoral and Popliteal Aneurysms - Due to its deep location, the popliteal artery is barely palpable in normal individuals. Prominent pulsation in the popliteal fossa is an indication that the patient may be harboring a popliteal aneurysm. Finding an aneurysm in these vessels should prompt a thorough evaluation because 50% are bilateral and 30% have an aortic aneurysm associated with them. Duplex ultrasonography can be used to confirm the diagnosis. Indications for intervention include thromboembolic complications and size. It is generally agreed that femoral aneurysms of greater than 2.5cm and popliteal aneurysms of greater than 2cm should be repaired. Here, unlike AAA’s, replacement with artificial graft is generally unnecessary, and usage of autogenous vein is feasible. Endovascular treatment with placement of covered stents that can exclude the aneurysm from the circulation is also a popular approach.
