彩色多谱勒超声对腹壁切口子宫内膜异位症的诊断价值

目的：探讨腹壁切口子宫内膜异位症的二维及彩色多谱勒超声特征。方法：回顾性分析15例经手术和病理证实为腹壁切口子宫内膜异位症患者的二维及彩色多谱勒超声图像。结果：15例患者肿物均位于腹壁切口内，其中9例肿物位于皮下脂肪层，5例肿物位于腹直肌内，1例肿物边界不清超出腹直肌几乎接受腹腔，肿物最大直径为0．7～4．4cm，无包膜，边界不清，形态不规则，内部回声不均质，部分内部见无回声。彩色多谱勒显示肿物内部及周边有星点状、短棒状和束状血流信号，为低速高阻的动脉频谱，最高速度（PSV）15．8～24．9cm／s，最低速度（EDV）4．1～5．8cm／s，阻力指数（RI）0．66～0．78。结论：彩色多谱勒超声对腹壁切口子宫内膜异位症的诊断具有重要的临床应用价值．

Value of color doppler ultrasonic examination in diagnosing abdominal incisional endometriosis

Objective:To explore the characters of two dimensional and color doppler ultrasonic imaging of abdominal incisional endometriosis.Methods:Retrospectively analyzed two dimensional and color doppler ultrasonic imaging of 15 cases with abdominal incisional endometriosis confirmed by surgery and pathological analysis.Results:All masses were in abdominal incision including 9 cases under subcutaneous fat,5 in rectus abdominis,and 1 extended over rectus abdominis and almost into peritoneal with ambiguous boundary.The diameter was 0.7~4.4 cm.All masses were uncoated,with ambiguous boundary,and irregular formation.Some had heterogenous internal echo,and some had no echo.The imaging showed star-like,cosh-like,and fasiculate blood flow signal in and near masses,which was arterial spectrum with slow speed and high resistance.The peak systolic velocity(PSV)was 4.1~5.8 cm/s,end diabolic velocity was 4.1~5.8cm/s,and resistance index was 0.66~0.78.Conclusion:Color doppler ultrasonic examination is valuable in diagnosing abdominal incisional endometriosis.
