目的总结剖宫产术后腹壁切口子宫内膜异位症(abdominal wall endometriosis,AWE)的超声表现,进一步提高AWE的诊断准确率。方法回顾性分析21例AWE患者的超声声像资料。结果 AWE肿块可位于皮下脂肪层、脂肪层与腹直肌前鞘之间及腹直肌内,形态不规则,边界不清,无包膜,呈不均质中低回声;经期肿块回声略低,并可见多个小液性暗区;肿块大小及内部回声可随月经周期发生动态变化;彩色多普勒显示17例肿块内无血流信号,4例可见星点状、短棒状或条束状彩色血流信号;频谱多普勒显示为低速高阻型的动脉血流频谱。结论根据AWE典型超声声像图表现,结合患者剖宫产病史和临床表现,可明确AWE诊断。
Objective To summarize the ultrasonographic findings of abdominal wall incision end of endometriosis (AWE) after cesarean section and to further improve the diagnostic accuracy of AWE. Methods Retrospective analysis of 21 cases of AWE ultrasound imaging data. Results AWE mass was located in the subcutaneous fat layer, between the fat layer and the anterior rectus sheath and the rectus abdominis, irregular in shape, with unclear border and no capsule, showing heterogeneous mid-low echo; , And showed a number of small liquid dark area; tumor size and internal echo can be dynamically changed with the menstrual cycle; color Doppler showed no mass flow signal in 17 cases, 4 cases can be seen star-shaped, short rod-like or bundle Shaped color flow signal; spectrum Doppler showed low-speed high-impedance type of arterial blood flow spectrum. Conclusion According to the AWE typical ultrasonography, combined with the history of cesarean section and clinical manifestations of patients can be clearly AWE diagnosis.
