CTA联合手持彩色多普勒超声设计小腿穿支螺旋桨皮瓣的临床应用

摘要

Objective To localise and evaluate the precise position of the shank perforators preoperatively with the CTA and hand-held color Doppler (HHD),then evaluate the clinical efficacy of the method.Methods From April,2013 to June,2017,designed 36 propeller perforator flaps in 36 patients by following methods.Firstly,the CTA test was performed to calculate the parameters of perforator vessel positioning.Secondly,a HHD was typically used to verify the location of perforators found on preoperative CTA.At last,according to the "like with like" principle,the propeller perforator flaps were accurately designed.The regular followed-up was performed.Results All patients were followed-up for 3-24 months after operation.Thirty-six propeller perforator flaps survived,and 3 cases among them showed partial epidermal necrosis and healed after skin grafting.Donor sites were closed primarily in 24 cases,and skin grafting were performed in 12 cases.The skin graft sites survived without necrosis,and the average time of cutting flaps was 45 min.Conclusion By the methods of mapping the perforator propeller flaps with CTA and HHD,the perforator vessel can be positioned more accurately and quickly.The operation time was shortened,and the clinical efficiency can be achieved with the good clinical application values.%目的 通过CTA联合手持彩色多普勒超声(HHD)进行精准定位穿支血管,设计小腿穿支螺旋桨皮瓣,并评估该方法的临床疗效.方法 自2013年4月-2017年6月,通过CTA联合HHD设计小腿穿支螺旋桨皮瓣36例.首先采用CTA检查测定穿支血管定位的相关参数,结合HHD确认穿支血管的位置,再通过形态相似的原则,精准的设计穿支螺旋桨皮瓣.术后定期随访.结果 术后对所有患者进行门诊随访3～24个月,36例穿支螺旋桨皮瓣均成活,3例皮瓣出现部分表皮坏死,后期植皮后愈合.24例供区直接缝合关闭伤口,12例需要取皮植皮,植皮区均成活,无1例坏死,平均皮瓣切取时间45 min.结论 通过CTA联合HHD设计穿支螺旋桨皮瓣,可以更加精准快速的定位穿支血管,缩短手术时间,达到很好的临床疗效,具有很好的临床应用价值.
