超声检查可用于诊断愈合不良的剖宫产疤痕。为研究了解能否改进子宫下段超声检查的精确性,1982年9月～1989年1月间,在三个诊所分别对孕37～38周的175例剖宫产疤痕进行常规超声扫查,从孕16周开始41例疤痕用新型超声诊断法进行连续扫查。疤痕扫查以1. 5或2. 0的放大率进行。必要时可用生理盐水充盈患者膀胱。子宫下段检查通过:①经腹纵行扫查(常规方法);②用3M 传导器经腹纵行扫查;③用或不用3 M 传导器经腹前位扫查,
Ultrasonography can be used to diagnose poorly healed caesarean section scars. To study whether or not the accuracy of ultrasonographic examination of the lower uterine segment can be improved, routine screening was performed on 175 cesarean scar pregnancies between 37 and 38 weeks at three clinics between September 1982 and January 1989. From Forty-one weeks after pregnancy, 41 cases of scar were scanned continuously with a new ultrasound diagnosis. Scar scanning to 1.5 or 2.0 magnification. When necessary, the bladder can be filled with saline. Examination of the lower uterine segment by: ① abdominal longitudinal scan (conventional method); ② with 3M transabdominal longitudinal scan; ③ with or without 3 M transversal anterior abdominal scanning,
