lower abdominal flap

The lower abdomen flap was taken from one side of the lower abdomen, more than the ipsilateral side of the affected side. It includes shallow movements of the abdominal wall, veins and squats, and the veins are the main ones. The projection line of the superficial abdominal artery is the edge of the femoral artery pulsation from the umbilicus to the inguinal ligament. The flap is designed as the central axis, the upper end can be flat umbilical, the lower end is 2~4cm under the inguinal ligament, the medial side is the midline of the abdomen, and the lateral anterior superior iliac spine [Fig. 1] The lower abdomen flap has a large donor area and contains more The subcutaneous fat tissue, the donor site can be directly sutured and sutured, so it is suitable for the repair of large wounds of the extremities, but the vascular variation is more. Treating diseases: burns electric burns Indication It is suitable for the repair of large wounds of the extremities, but there are more vascular variations. Surgical procedure A straight incision about 8 cm in length along the femoral artery at the upper end of the femur is connected to the incision on both sides of the lower end of the flap to form a Y-shape. In the incision, the superficial vein of the abdomen, the superficial sacral vein and the saphenous vein were exposed, followed by the femoral artery, and the shallow artery of the abdominal wall was exposed along the movement in the initial segment of the femoral artery. The starting point of the superficial temporal artery is more than the inner side of the femoral artery, about 1 cm from the inguinal ligament, and is released upward until it enters the flap. The skin was cut around the flap, and the aponeurosis of the external oblique muscle was directly obtained. Then, the flap was separated from the upper and lower oblique aponeurosis of the external oblique muscle, and only the vascular pedicle of the lower end of the flap was continuous.
