剖宫产术后腹壁瘢痕子宫内膜异位症的彩超诊断

Diagnostic value of color doppler ultrasonography for the endometriosis in the scar abdominal wall after caesarean section

目的:探讨高频超声与彩色多普勒血流显像(CDFI)对腹壁切口瘢痕处,子宫内膜异位症的超声表现。方法:对26例经手术病理证实的腹壁瘢痕子宫内膜异位症的声像图特征进行分析。结果:腹壁瘢痕处探及边界不清,形态不规则,无包膜,内部回声不均质的中低回声团块,团块内呈斑片状液性暗区间杂弱回声光点及条带状低回声;CDFI:显示肿块周边及内部有点状、短棒状和条状血流信号。脉冲多普勒(PW)表现为低速高阻的特点,Vs5.0～20cm/s、RI0.65～0.82。结论:高频超声结合CDFI和PW能对剖宫产术后腹壁瘢痕子宫内膜异位症进行明确诊断,为临床提供可靠的诊断应用价值。

Objectives：To study the value of high-frequency ultrasonic and CDFI for the diagnosis of the endometriosis in the scar abdominal wall after caesarean section.Methods：26 patients who had been authenticated with the endometriosis in the scar abdominal wall by pathological examination were investigated via ultrasonography.Results：An intermediate frequency echo or low frequency echo conglomeration had been found in the scar abdominal wall,and the border was blurry,the shape was erase,the envelope was not found,and flecky liquid dark areas with low frequency echo photic points and zonary low frequency echo could be found in the conglomeration. CDFI： punctate and short club-shape or zonary blood stream signal could be found in the conglomeration.PW showed low speed and high resistance characteristic,Vs 5.0-20 cm/s,RI 0.65-8.2.Condusion：Using high frequency ultrasonography combined with CDFI and PW,the exact diagnosis can be given to the endometriosis in the scar abdominal wall,thus good advise is provided for the clinical diagnosis.
