腹壁浅动脉蒂游离腹壁皮瓣乳房再造术的初步临床应用

Breast reconstruction with superficial inferior epigastric artery flap

目的 探讨采用腹壁浅动脉（superficial inferior epigastric artery,SIEA）蒂游离腹壁皮瓣乳房再造术方法 、特点及适应证.方法 术前采用多层螺旋CT（multipledetector-row computed tomography,MDCT）三维血管造影及多普勒血流探测仪检查SIEA的直径、走行及分布,于脐与阴阜上缘之间设计皮瓣,采用单蒂或双蒂SIEA,与胸廓内动,静脉吻合,腹部供区直接拉拢缝合.结果 4例乳房再造病例皮瓣全部存活,皮瓣和腹部供区无脂肪液化、坏死、切口裂开、腹壁薄弱及腹壁疝等并发症的出现,再造乳房外形效果满意.结论 SIEA蒂游离腹壁皮瓣与腹壁下动脉穿支皮瓣（DIEP）,横行腹支肌肌（TRAM）皮瓣乳房再造术提供同样的腹部皮肤和组织量,但却减轻了对腹部功能和形态的损害,在做好充分的术前血管评估、严格把握适应证和熟练掌握显微外科技术的前提下,是一种可供选择的乳房再造方法.

Objective To present a method for breast reconstruction with the superficial inferior epigastric artery （S1EA） flap and to summarize the operative experiences. Methods The diameter and distribution were evaluated with multipledetector-row computed tomography （MDCT） angiography and doppler perfusion flowmeter. Bipedicle superficial inferior epigastric artery flap was designed below umbilicus. Superficial inferior epigastric artery and vein were anastomosed to the internal mammary artery and vein. Results Since 2007, we have used the superficial inferior epigastric artery flap in 4 cases of breast reconstruction. Four flaps survived completely. With the follow-up of 6-12 months, the reconstructed breasts were well-shaped and there were no complications such as abdominal hernia, bulge and weakness in donor sites. Conclusions Breast reconstruction using the superficial inferior epigastric artery flaps can not only preserve the advantages of the traditional method using the deep inferior epigastric perforator flaps, but also retain the maximal function of the fascia and the rectus abdominal muscle and prevent the occurrence of abdominal weakness and hernia. It is an ideal alternative method of breast reconstruction on condition that definitive preoperative assessment of vessels and skilled surgical technique are provided.
