前次剖腹产再妊娠时,了解疤痕愈合情况对预防子宫破裂十分重要,但目前尚无理想的诊断方法.本文介绍在孕末期超声断层检查的结果.研究对象为在作者医院做过剖腹产的21例产妇,以同期住院未行剖腹产的24例为对照.检查时间在孕34～42周,检查时膀胱需充满尿液.探头先沿矢状方向从左到右进行,再沿偏离矢状方向20°～30°左右斜行,第三步在下腹部横行移动检查.要尽可能描出膀胱回声及其界线.摄影时要屏住呼吸.由于切口处疤痕被膀胱覆盖,直接测量该部厚度困难,故用膀胱与胎先露间距即B-F间隔做为断层观察指标.以胎头或胎臀曲线与膀胱壁
In the previous caesarean section, it was very important to understand the healing of the scar to prevent uterine rupture, but there is no ideal diagnostic method.There are 21 cases of caesarean section in the author’s hospital Maternal, with the same period of hospitalized 24 cases of caesarean section as a control.Checking time in 34 to 42 weeks of pregnancy, check the bladder to be filled with urine.The probe first along the sagittal direction from left to right, and then deviate from the sagittal direction 20 ° ~ 30 ° oblique line, the third step in the lower abdomen transverse movement check. As far as possible to describe the bladder echo and its boundaries. Photographing to hold your breath. As the incision at the bladder coverage, direct measurement of the thickness of the Ministry of hard, so Bladder and fetal exposed space that BF interval as a marker of observation to the fetal head or fetal hip curve and the bladder wall
