Abstract:
In many textbooks and literatures the superficial circumflex iliac artery (SCIA) is generally described, but only its superficial main branch (SMB) is referred, Its deep main branch (DMB) is always neglected, though it is present constantly. In 56％ of fifty cases we studied the SCIA trunk possesses both these main branches.The SMB is present in 86％ of the cases studied. After it originates from the trunk, it usually emerges promptly from the back of deep fascia into the subcutaneous layer. The points of emergence were found in an area around a center located 15 mm lateral and 10 mm below the origin of femoral artery. The course of the SMB can be marked as a line which located between a point 15 mm below the origin of femoral artery and anterior superior iliac spine. The SMB supplies an area along the lateral half of inguinal ligament, and its terminal branch usually turns upwards to the lateral portion of the abdominal wall.The DMB is a constant branch in our cases. It runs parallel to and 15mm beow the inguinal ligament, It supplies the upper lateral portion of the thigh, and its terminal branch usually turns downwards and laterally into the superficial layer of the gluteal region. The site where the DMB penetrates the deep fascia was found in an area around a center located 20 mm below the anterior superior iliac spine.The caliber of each of the two main branches is intimately correlated with the size of the skin which supplies. The course of the(SCIV)is similar to one of the main branches of the SCIA or runs between them (70％) The axes, thickness, size of the groin skin flaps were discussed.
