Table 1: Classification of popliteal artery branching patterns in the leg.
Class | Vascular Pattern |
I-A I-B I-C II-A1 II-A2 II-B II-C III-A III-B III-C III-D |
Usual pattern Trifurcation: AT, PT and PER arise below knee within 0.5 cm of each other Anterior tibioperoneal trunk: PT is first branch, then TPT bifurcates into PER AND AT AT arises at or above the knee joint, with normal course in its proximal segment AT arises at or above the knee joint, with medial curve in its proximal segment PT arises at or above the knee joint, common trunk of AT and PER PER arises at or above the knee joint, common trunk of AT and PT Hypoplastic or aplastic PT, distally replaced by PER Hypoplastic or aplastic AT, DP replaced by PER Hypoplastic or aplastic AT and PT, DP and PT replaced by PER (Arteria Peronea Magna) Hypoplastic or aplastic PER |
AT: Anterior Tibial artery, DP: Dorsalis Pedis artery, PT: Posterior Tibial artery, PER: Peroneal Artery, TPT: Tibioperoneal Trunk.
