目的探讨彩色多普勒超声在带蒂穿支皮瓣术前设计及术后血流动力学监测中的应用价值。方法对29例行带蒂穿支皮瓣修复术患者,应用彩色多普勒超声诊断仪对皮瓣供区穿支动脉术前定位、标记并监测其术前及术后血流动力学指标。结果 (1)术前超声检出供区主干动脉29条,穿支动脉62条,均与术中检查到的穿支动脉数量、位置相符,检出率达100%,未见血管缺如及变异现象。(2)术后1~7d蒂部穿支动脉Vmax、Vmean、Vmin逐渐升高,14、30d下降,但仍高于术前水平。(3)术后1~14d蒂部穿支动脉PI、RI逐渐下降,30d略升高,但仍低于术前水平。结论彩色多普勒超声在带蒂穿支皮瓣术前设计及术后血流动力学的监测方面有很好的临床应用价值。 Objective To investigate the value of color Doppler ultrasonography in the preoperative design and postoperative hemodynamic monitoring of pedicle pedicled perforator. Methods Twenty-nine patients with pedicled pedicled perforator flap were repaired. Color Doppler ultrasonography was used to locate the perforator for the perforator artery, and the preoperative and postoperative hemodynamic indexes were marked. Results (1) Preoperative ultrasound for the area for the detection of 29 main arteries, perforation of the artery 62, both with the number of perforating branches detected during surgery, the location, the detection rate of 100%, no absence of blood vessels and Variation phenomenon. (2) The Vmax, Vmean and Vmin of the perforating branches of peduncles increased gradually from 1 to 7 days after operation and decreased on the 14th and 30th days, but still higher than the preoperative levels. (3) The PI and RI of the pedicel peduncle gradually decreased from 1 to 14 days after operation, slightly elevated at 30 days, but still lower than the preoperative level. Conclusions Color Doppler ultrasound has good clinical value in the preoperative design of pedicle pedicled perforator flap and postoperative hemodynamic monitoring.
