Excerpt

Popliteal artery aneurysms occur when the diameter of the popliteal artery undergoes focal dilation and exceeds 50% of its normal range. The normal diameter of the popliteal artery ranges from 0.7 to 1.1 cm. Popliteal artery aneurysms manifest as either fusiform (diffuse dilation) or saccular (asymmetrical) dilations and constitute a significant majority, comprising 85% of all peripheral aneurysms. Notably, popliteal artery aneurysms are frequently associated with abdominal aortic aneurysms, with a prevalence of 40% to 50%.

The popliteal artery is considered a continuation of the superficial femoral artery after it passes through the adductor magnus hiatus. The vessel traverses the popliteal fossa alongside the vein and terminates by bifurcating into the anterior tibial artery and tibioperoneal trunk, situated at the lower border of the popliteus muscle, aligned with the tibial tuberosity level.
