A rare variation of trifurcation of right femoral artery

Introduction The anatomy of the vessels of lower limb has long received attention from various scientists and author. The femoral artery enters the thigh at a point midway between the anterior superior iliac spine and the pubic symphysis. Here it lies on the psoas major tendon, which separates the artery from capsule of the hip joint. This is the position where its pulsation can be felt and where it can be entered for arterial catheterization. Cannulation, the femoral artery is second only to the radial as the site of choice for the placement of an arterial line. Its superficial position below the inguinal ligament makes it easily accessible. The most common complications include retroperitoneal hemorrhage and perforation of the gut and arterio-venous fistula. The lateral circumflex femoral artery occasionally arises from femoral artery [1]. An expansile swelling lying along the course of the femoral artery that fluctuates in time with the pulse rate should make the diagnosis of aneurysm of the femoral artery certain [2].The lateral and medial femoral circumflex arteries are typically the largest branches of the profunda femoris although they do not always arise from this vessel; either or both may arise as branches of the femoral artery itself above the origin of the profunda femoris. In any case, they originate in the femoral triangle whether they arise from the profunda femoris or from femoral artery, they may share a common stem or have separate origins [3].
