Abstract

The superficial position of the femoral artery makes it readily accessible for catheterisation. The femoral artery is used in interventional cardiology procedures and as an access for permanent haemodialysis. The femoral artery and its main branch, the profunda femoris artery are used in arteriography and in doppler imaging. Skin flaps based on the superficial branches of the femoral artery are used in reconstructive procedures of the breast, upper and lower extremities. It is difficult to achieve haemostasis in anomalous conditions, when the femoral artery is punctured for cannulation. Hence a detailed knowledge of the branching pattern of the femoral artery is needed to minimise complications. The anatomy of the femoral artery was studied in 50 adult lower limb specimens at the Institute of Anatomy, Madras Medical College. 25 adult femoral angiograms and 10 CT angiograms of the femoral artery from the Barnard Institute of Radiology, Rajiv Gandhi Government General Hospital were also studied. The origin of the femoral artery coincided with the mid inguinal point in 88% and was lateral to it in 12%. The superficial epigastric artery arose as a separate trunk from femoral artery in 88% and as a common stem with superficial external pudendal artery in 12%.There was duplication of superficial external pudendal artery in 8%.The profunda femoris artery arose from the posterolateral aspect of the femoral artery in 64%, from its posterior side in 24%, and from its lateral side in 12%. The mean length of the profunda femoris origin from the mid inguinal point was 4.31cm. The lateral circumflex femoral artery originated from the profunda femoris in 72% and from the femoral artery in 28%. The medial circumflex femoral artery originated from the profunda femoris in 64% and from the femoral artery in 36%. In the radiological study done, normal branching pattern was observed in 84% and variant branching pattern was seen in 12%. The present study will be useful to the surgeons while operating around the femoral region. The knowledge of the femoral artery will also help the radiologists during interpretation of images, and the clinicians before proceeding with interventional procedures.
