目的：探讨彩色多普勒血流显像（CDFI）在设计旋股外侧动脉（LCFA）穿支皮瓣的临床应用价值。方法：2015年1月—2016年11月我院临床收治的32例拟行LCFA穿支皮瓣修复手术的患者，术前应用CDFI检测LCFA降支起点位置、穿支血管（管径≥0．5 mm）的数量、内径、穿深筋膜位置及峰值流速并进行体表标记，选用管径粗、峰值流速快、肌间走行短的穿支血管设计皮瓣，将术前检测结果与术中的情况进行对比。结果：32例患者共检测到穿支动脉72支，管径0.5～1.5 mm，其中肌皮穿支57支，肌间隙穿支15支。术中证实穿支血管69支，准确率为95.8%。皮瓣范围内仅探及1条穿支血管2例，2支12例，3支16例，3支以上2例。结论：CDFI在术前LCFA穿支皮瓣设计方面有很好的临床应用价值。
Abstract
Objective: To evaluate the applied value of CDFI in lateral circumflex femoral artery(LCFA) perforator flaps. Methods: Thirty-two patients were treated by our hospital from Jan. 2015 to Nov. 2016, perforating branches of LCFA were examined in 32 patients using CDFI. The following parameters were detected: jumping-off point, number, diameter(≥0．5 mm)，course, location and peak blood velocity, and they were marked on patients’ body surface. The perforator with wider caliber, faster flow speed, and shorter intramuscular trajectory was selected, and the flap was designed according to the observed results. Results: Thirty-two trunk arteries and 72 perforating arteries were examined and 69 confirmed by operation with an accuracy rate of 95.8%. The inner diameter ranged from 0.5 mm to 1.5 mm. Thirty-two cases of patients, and among which 57 were myocutaneous perforator, 15 were septocutaneous perforator. Totally, 2 patients were detected by CDFI only 1 perforator in the flap area, 12 patients were detected 2, 16 patients were detected 3, and 2 patients were detected 3 or more. Conclusion: CDFI had much higher application value in designing perforator flap of LCFA before the operation.
