彩超诊断剖宫产术后腹壁疤痕子宫内膜异位症

目的探讨剖宫产术后腹壁疤痕子宫内膜异位症(简称腹壁内异症)的彩色多普勒超声表现。方法对8例经手术和病理证实的腹壁内异症的彩色多普勒超声结果进行回顾性分析。结果8例肿物均位于皮下脂肪层,直径为1.6～3.7cm;形态不规则,边缘不光滑,常呈毛刺状侵及腹直肌前筋膜;内部呈不均匀的低回声,可见一个或数个小的液性暗区;彩色多普勒显示肿物内部均可见点状和/或条状血流信号,为低速高阻的动脉血流。结论与临床资料相结合,彩色多普勒超声是诊断腹壁内异症的一种有价值的方法。

Abdominal wall endometriomas near cesarean delivery scars diagnosed by color Doppler ultrasound

Objective To describe the sonographic and color Doppler features of abdominal wall endo-metriomas near cesarean delivery scars.Methods Ultrasonographic appearances of abdominal wall endometriomas of 8 patients confirmed by pathology and operation were analyzed retrospectively. Results Sonography disclosed that all nodules were located at subcutaneous tissue.The nodules size was 1.6-3.7cm. The sonographic features were irregular shape and irregular margins, often speculated, infiltrating the muscularis fascia; a hypoechoic in homogeneous echo texture with internal anechoic lacunae.Color Doppler examination showed that the color signal pattern was dot-like and/or linear with low-velocity and high-resistance arterial flow in all the patients.Conclusion Color Doppler ultrasound,when properly combined with clinical data,may be a valuable method for diagnosing abdominal wall endometriomas.
