彩色多普勒超声对腹壁瘢痕子宫内膜异位症的诊断价值

目的探讨腹壁瘢痕子宫内膜异位症的二维及彩色多普勒超声特征.方法对7例经手术及病理证实的腹壁瘢痕子宫内膜异位症的超声图像进行回顾性分析.结果腹壁瘢痕处探及边界不清、形态不规则、内部不均质的低回声肿块,彩色多普勒血流显示肿块周边部血流信号丰富,多普勒频谱表现为低速高阻的特点,PSV 6.5～19 cm/s,RI 0.71～0.85.结论彩色多普勒超声有助于对腹壁瘢痕子宫内膜异位症的诊断与鉴别诊断.

Diagnosis of abdominal wall scar endometriosis by color duplex ultrasonography

Objective To describe the features on two-dimensional and color Doppler ultrasonography of abdominal wall scar endometriosis.Methods Ultrasonographic appearances of endometriosis in abdominal wall scar confirmed by pathology in 7 patients were retrospective analyzed.Results Their ultrasonographic features were mass-like structure with ill-defined and irregular contour,heterogeneous and hypoechoic internal echoes in the abdominal wall scar. There were masses with peripheral hypervascularity on color Doppler flow imaging. Spectral Doppler revealed low speed (PSV 6.5-19 cm/s) and high resistance (RI 0.71-0.85).Conclusion Ultrasonography is helpful to the diagnosis and differential diagnosis of abdominal wall scar endometriosis.
