Transabdominal amnioinfusion improves the diagnostic accuracy of ultrasonography in pregnancies complicated by second-trimester oligohydramnios. Needle localization may be difficult because of patient obesity or the absence of an acoustic window. The two cases presented demonstrate that color Doppler imaging facilitates amnioinfusion by visualizing the injection jet of free-flowing infusate, confirming intraamniotic needle placement.
经腹羊膜腔灌注可提高超声对妊娠中期羊水过少合并妊娠的诊断准确性。由于患者肥胖或缺乏声学窗,可能难以进行针定位。所呈现的两例病例表明,彩色多普勒成像通过显示自由流动的灌注液的注射射流来辅助羊膜腔灌注,从而确认羊膜腔内针的位置。
