The Arterial Branching Pattern of the Common Femoral Artery: A Case Report

IntroductIonThe inguinal (Poupart's) ligament, the external iliac artery extends as the common femoral artery (CFA) in the femoral triangle in front of the thigh.Here, the artery has three superficial branches: epigastric, external pudendal, and circumflex iliac.Two deep branches are given, deep external pudendal and deep femoral artery (DFA), which is also known as the profunda femoris (largest branch).The DFA takes it origin from 3 to 4 cm below the inguinal ligament, after which the CFA continues as the superficial femoral artery (SFA).The DFA takes origin usually from the posterolateral aspect of the CFA, and then, it proceeds medially.The DFA gives lateral and medial circumflex femoral branches along with perforating branches. 1 These branches participate in various anastomoses.In cases of occlusion of the SFA, the DFA forms a collateral circulation between the iliofemoral part and the branches of the popliteal artery. 2 The knowledge of anatomical variants of femoral arteries is important as it can prevent iatrogenic injuries during diagnostic procedures and surgeries in the region of the femoral triangle, especially vascular reconstruction and catheterization. 3dIscussIon In the anterior aspect of the thigh, the SFA develops from the rete femorale, which forms communications with external iliac artery 1-
