“盘绕征”在产前超声诊断胎儿空、回肠闭锁中的价值

Value of“coil sign”in prenatal ultrasonic diagnosis of fetal jejunal and ileal atresia

目的探讨“盘绕征”在产前超声诊断胎儿空、回肠闭锁中的临床应用价值。方法回顾性分析经我院产前超声诊断并经产后手术或引产后尸体解剖证实的5例空、回肠闭锁胎儿的资料,总结其声像图特点。结果5例空、回肠闭锁胎儿中,产前超声表现为“盘绕征”4例,经手术或尸体解剖证实为空、回肠盲端闭锁(肠管连续性中断);无“盘绕征”表现的1例经尸体解剖证实为回肠及降结肠隔膜闭锁(肠管连续性无中断)。结论“盘绕征”可以作为产前超声诊断空、回肠盲端型闭锁直接征象。

Objective To explore the value of“coil sign”in prenatal ultrasonic diagnosis of fetal jejunum and ileum atresia.Methods The data of 5 cases of fetal jejunum and ileum atresia diagnosed by prenatal ultrasound and confirmed by postnatal operation or postnatal autopsy after labor induction were retrospectively analyzed,and the sonographic characteristics of the fetuses were summarized.Results Among the 5 fetuses with jejunum and ileum atresia,4 cases showed“coil sign”on prenatal ultrasound,which was confirmed by autopsy as the jejunoileal atresia of blind end type(continuous interruption of the intestine),1 case without“coil sign”was confirmed by autopsy as diaphragm atresia of ileum and descending colon(uninterrupted bowel continuity).Conclusion The“coil sign”can be used as a direct sign of prenatal ultrasonography in the diagnosis of jejunum and ileum atresia.
