摘　　要：目的:探讨微泡增强多普勒超声技术(MEUS)在穿支皮瓣术前定位中的价值。方法:选取33例于本院接受皮瓣移植术的患者,术前分别用彩色多普勒血流显像(CDFI)和MEUS检测皮瓣供区的穿支血管及脂肪层的小血管数目,比较两者显示穿支血管及脂肪层小血管的差异。根据穿支血管的内径、走行、峰值流速、阻力指数等指标选择最优穿支。33例患者中,术前共设计35个皮瓣,大小范围为3.5cm×5.5cm~15.0cm×11.0cm,术中共切取35个皮瓣,每个皮瓣包含1~3条穿支血管。以术中结果为金标准,比较CDFI和MEUS的诊断效能。结果:MEUS检测供区穿支数目优于CDFI(P<0.05);MEUS检测脂肪层小血管数目优于CDFI(P<0.05);MEUS诊断穿支的Kappa值(0.867)大于CDFI(0.715),且MEUS的灵敏度优于CDFI(P<0.05)。结论:MEUS对穿支血管和脂肪层血流灌注的检测优于CDFI,MEUS有助于皮瓣微循环的显示。Objective:To investigate the value of MEUS in preoperative localization of perforator flap.Methods:33 patients who underwent flap transplantation were selected,and the color Doppler flow imaging(CDFI)and MEUS were used to detect the number of small vessels in the flap supply area,and compare the difference between perforator vessels and small vessels in the fat layer.The optimal perforator was selected according to the inner diameter,walking,peak flow velocity and resistance index of the perforating vessel.Among the 33 patients,35 flaps were designed with a size range of 3.5cm×5.5cm-15.0cm×11.0cm,and 35 flaps were cut,and each flap contained 1 to 3 perforator vessels.The diagnostic efficacy of CDFI and MEUS was compared using intraoperative outcome as the gold standard.Results:MEUS was better than CDFI in detecting perforator vessels(P<0.05);MEUS was better than CDFI in detecting small blood vessels in the fat layer(P<0.05);Kappa value(0.867)of MEUS in diagnosis of dominant perforators was higher than CDFI(0.715),the sensitivity of MEUS was better than that of CDFI(P<0.05).Conclusion:MEUS is better than CDFI in detecting perforator vessels and blood flow perfusion of fat layer,MEUS is helpful to display microcirculation of flap.
