Rare origin of the inferior epigastric and medial circumflex femoral arteries arising from a common trunk

Abstract

A case of unilateral anomalous arterial supply of the lower limb and the anterior abdominal wall is presented. In this case, inferior epigastric artery arose from a common trunk with the medial circumflex femoral artery. The common trunk arose from the femoral artery. The inferior epigastric artery reached the anterior abdominal wall by passing deep to the inguinal ligament. The medial circumflex artery ran between the femoral artery and vein within the femoral triangle. A possible ontogenetic explanation is provided for this situation. Awareness of the variations in anatomy of the inferior epigastric and femoral arteries is important for angiographers and the surgeon who operates in this region.
