Deep inferior epigastric artery (DIEA) skin flap: clinical experience of 15 cases.
Skin flaps devoid of rectus muscle, raised on a single musculocutaneous perforator (14 cases), and on two musculocutaneous perforators (1 case) of the deep inferior epigastric artery (DIEA) were used in 14 patients to cover various defects during a period of 3 years. The flaps were raised on the perforator arising slightly lateral to the centre of the muscle below the umbilicus, which is a sub-branch of the lateral branch of DIEA. The defects were located on the upper limb in four, the lower limb in nine, and the scalp and forehead in the remaining two cases. In one patient, the flap was preexpanded for 4 weeks prior to transfer. The longest flap was 40 x 12 cm, and the widest flap was 30 x 18 cm in dimension. All donor defects were closed primarily. Two flaps were lost due to venous thrombosis on the fourth postoperative day. Tip necrosis was observed in two flaps, both of which were salvaged from venous thrombosis at 36 hours and 5 days postoperatively. The remaining 11 flaps survived completely. The DIEA skin flap was found to provide the following benefits: (1) the largest available skin flap where the donor site could be closed primarily; (2) decreased possibility of abdominal wall weakness and hernia formation; and (3) potential of obtaining a thin flap either by trimming of the subcutaneous fat or by preexpansion.
