A rare case of anatomical variation of the femoral artery and vein

Abstract

During a dissection of the two femoral trigons in a female corpse, about 14 years old, we discovered on the right side, the deep artery of the thigh arising from the medial side of the femoral artery and passed in front of the femoral vein above the mouth of the great saphenous vein; on both sides, there was the presence of a collateral canal which communicated the external iliac vein with the femoral vein on the right, on the left, it communicated the external iliac vein with the quadricipital vein. The lower part of the femoral vein was duplicated on both sides, but on the right, there was an interconnecting channel between the two trunks of the duplication. Variations of the femoral vessels are very frequent and can be responsible for an incident during the practice of certain gestures at the level of the femoral trigon such as: catheterization of the femoral artery or vein, the treatment of femoral hernias.
 Key words: Deep thigh artery, collateral venous canal, external iliac vein, anatomic variations.
