[The lateral abdominal island flap--the lateral intercostal neurovascular island flap].
This work studied the lateral abdominal island flap, its clinical value, transposition range and the practicability of a modified operative method. Five lateral abdominal island flaps were used in 5 patients. Four of them were for axillary radiation ulcers after radical mastectomy. One was for a sacral defect after resection of a recurrent fibrosarcoma. All the flaps obtained satisfactory results. Clinical applications revealed that the blood supply of the lateral abdominal skin was mainly from the lateral cutaneous branches of the 9th, 10th and 11th intercostal arteries, among which there were numerous anastomoses. The lateral abdominal island flap can be pedicled with any of these lateral cutaneous branches. The long pedicle of the flap provides a wide range of trnasposition from the axilla to the sacrum. As the pedicle of the flap contains the lateral cutaneous branch of the intercostal nerve, the flap can bring sensation function to the recipient area. The modified operative method of the lateral abdominal island flap is introduced.
