Femoral Artery, Posterior View

Description

Running deep along the posteromedial thigh, the femoral artery is followed distally to the adductor hiatus, where it emerges posteriorly to become the popliteal artery in the popliteal fossa. Superficial to this course sit the gluteus maximus proximally and the hamstring group (biceps femoris laterally, semitendinosus and semimembranosus medially), with the distal femur superior to the tibial plateau and fibular head. Branching vessels track along the posterior compartment musculature, while companion veins parallel the arterial pathway, and fine neural elements course near the vessels and between muscle planes. A key landmark. That transition through the adductor hiatus matters in practice because it is where the vessel changes both name and surgical exposure, shifting from the anterior thigh (femoral triangle and adductor canal) to a posterior position where it lies close to the capsule of the knee and adjacent neurovascular structures. Popliteal artery entrapment syndrome relates directly to the popliteal segment’s relationship with the medial head of gastrocnemius and nearby tendinous bands, and popliteal aneurysms commonly present with distal embolization or compressive symptoms against the tibial nerve. For bypass planning, the illustration clarifies why distal femoropopliteal grafting targets differ depending on whether the lesion is above or below the adductor hiatus. Ideal for gross anatomy teaching of the thigh compartments and the adductor canal to popliteal fossa continuum, and for vascular surgery or interventional radiology materials that discuss femoropopliteal occlusive disease, posterior knee approaches, or catheter navigation across the adductor hiatus. It also supports patient-facing explanations of where claudication-producing stenoses occur along the femoral to popliteal pathway. Anatomical accuracy verified by SciePro's Medical Advisory Board.
