Superficial Femoral Artery

The Superficial Femoral Artery and its branches (Gray's Anatomy)

The Superficial Femoral Artery (SFA) is a large artery in the thigh that supplies blood to the lower extremity. It is a continuation of the femoral artery after it passes through the adductor hiatus, a gap in the adductor magnus muscle.

Anatomy

The SFA begins at the level of the adductor hiatus and ends at the popliteal fossa, where it becomes the popliteal artery. It is the main blood supply to the muscles and skin of the thigh. The SFA gives off several branches, including the deep femoral artery and the descending genicular artery.

Clinical significance

The SFA is often involved in peripheral arterial disease (PAD), which can lead to claudication, ischemia, and gangrene. It is also a common site for angioplasty and stenting procedures.
