Anatomical variants of the profunda femoris artery: an angiographic study.

The bifurcation of the common femoral artery (CFA) into superficial and profunda femoris arteries (PFA) and the branching pattern of the PFA are subject to considerable normal anatomical variation. These variation patterns were assessed on normal lower limb angiograms of 94 adult patients. The main pattern (in 81% of patients) consisted of both medial and lateral circumflex arteries arising directly from a PFA situated lateral or posterolateral to the femoral artery. Previous studies of arterial variations in this region and the relevant embryology are reviewed. Relevance to angiographic procedures of the lower limb is discussed.
