摘　　要：目的探讨术前采用增强CT辅助设计带蒂腹壁下动脉穿支(deep inferior epigastric perforator,DIEP)皮瓣的方法及效果。方法2007年6月-2008年3月,7例患者接受增强CT辅助设计的带蒂DIEP皮瓣移位修复手术。女5例,均为先天性无阴道;男2例,均为阴茎阴囊Paget’s病。年龄18～62岁。术前患者均行增强CT扫描检查,寻找腹壁下动脉的粗大穿支血管。术中根据寻找结果进行皮瓣设计。2例修复阴囊阴茎缺损,5例完成阴道再造。皮瓣切取范围为15cm×7cm～22cm×5cm。供区直接拉拢缝合。结果7例术前共选出10支理想穿支血管,直径均>1.5mm。其中4例1支,3例2支。术中证实穿支血管走行与增强CT检查完全吻合。术后7例皮瓣均顺利成活。6例切口Ⅰ期愈合,1例Paget’s病患者术后7d出现邻近阴囊切口糜烂,并部分坏死,予间断换药后愈合。供区切口均Ⅰ期愈合。术后2例诉术侧下腹部牵扯不适,7d后自行缓解。患者均获随访,随访时间1～10个月,平均4.5个月。无皮瓣相关并发症发生。6例患者对修复效果满意,1例Paget’s患者希望再次手术改善阴茎外形。结论增强CT辅助DIEP皮瓣设计,不仅能提高皮瓣的安全性,还能减少手术时间,提高手术效率。Objective To explore the effect of the intensive CT on the deep inferior epigastric perforator （DIEP） flap design strategy. Methods From June 2007 to March 2008, 7 patients received reconstructive operation of the vertical DIEP flap, among whom there were 5 females with congenital absence of vagina and 2 males with peno-scrotal Paget＇s disease, aged 18-62 years old. Before the operation, the intensive CT scans were applied to all the petients in search for DIEP. The flaps were designed according to the radiological findings. The scrotum and penis defects were reconstructed in 2 cases and vaginal reconstruction was performed in 5 cases. The flap dimension ranged from 15 cm × 7 cm to 22 cm × 5 cm. The donor site was closed directly. Results A total of 10 ideal perforating branches of all the 7 DIEP flaps were found before the operation, with the diameter of over 1.5 mm. Of the 7 flaps, 4 had 1 perforating branch and the other 3 had 2 perforating branches. All 7 flaps survived completely. The incisions of 6 patients obtained healing by first intention. Only 1 patient with Paget＇s disease had erosion at the scrotum incision and partial necrosis 7 days after the operation, and then healed after discontinuous dressing change. The incisions at the donor site obtained healing by first intension. Two patients complained about draw-off at the lower abdomen on the operated side, which was basically relieved at 7 days after the operation. All patients were followed up for 1 to 10 months （4.5 months on average）. No operation-related complication was observed after operation. Six patients were satisfied with the reconstructive results. Only 1 patient was dissatisfied with the buried pennies and requested a revision. Conclusion The intensive CT scans play an important role in the DIEP flap design. It can not only make the flap safer, but also decrease operation time and improve efficiency.
