Abstract:
In many textbooks and literature, the course and distribution of the superficial epigastric artery (SEA) was described as a single vessel corresponding to the medial main branch (MMB) in our series, the lateral main branch (LMB) was always neglected. In 20% of fifty cases we observed, the SEA possesses a trunk which divides into two main branches.The LMB is present in 66%. It enters the superficial fascia by passing through the fascia lata. The penetrating points of the LMB are found mostly around a center 5 mm lateral and 15 mm distal to the origin of the femoral artery. It ascends along a vertical line 10 mm lateral to the origin of the femoral artery, and supplies the lateral part of the middle portion of the lower abdomen at that side.The MMB is present in 68%. It enters the superficial fascia by passing through the fossa ovalis. The penetrating points of the MMB are found mostly around a center 25 mm distal to the origin of the femoral artery. It ascends along a vertical line 10mm medial to the origin of the femoral artery, and supplies the medial half of lower abdomen at that side.The caliber of each main branch is intimately correlated with the area of the skin it supplies. The axis, depth, distribution of the SEA or its main branches as vessels of the skin flaps at groin region has been discussed.
