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

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 erose,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.Conclusion: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.
