侧腹部岛状皮瓣

The lateral abdominal island flap——the lateral intercostal neurovascular island flap

本研究目的在于探讨侧腹部岛状皮瓣可移转到达的部位、临床价值和改进的手术方法是否可行。通过5例(4例乳癌根治术后放疗致腋部放射性溃疡,1例骶部纤维肉瘤术后复发需再次广泛切除)的修复实践均得到了令人满意的效果。结论认为侧腹部皮肤的血运主要由第9,10,11肋间动静脉外侧皮支供给,各支间相互吻合交通,由其中任何一条动静脉为蒂均可保证岛状皮瓣的成活。血管蒂可分离得较长,皮瓣能移转到达的部位较广,并可带有肋间神经外侧皮支,成为有感觉的皮瓣。经实践证明改进的手术方法也切实可行。

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 nu- merous anastomoses. The lateral abdominal island flap can be pedicled with any of these lateral cuta- neous branches, The long pedicle of the flap provides a Wide range of transposition 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 ab- dominal island flap.is introduced.
