[Unusual variation of popliteal arterial branches: 4 axes by early division of the peroneal artery].
Embryonic development of arteries of the lower limb results from the union of dorsal and ventral systems, explaining many variations at different levels. Some of these are important to recognize during the radiological exam because they can affect therapeutic management. These variations are most often bilateral and symmetrical predominating at the popliteal and subpopliteal levels. Lippert classified them into three types: normal level of popliteal arterial branching, high division of popliteal artery, hypoplastic or aplastic branching with altered distal supply. The length of the tibioperoneal trunk may also vary, rarely measuring more than 5 cm. We report a case combining three variations, two of them previously described in the literature and the third one not yet reported: our patient presented four arteries due to early bifurcation of the peroneal artery.
