胎儿消化系统畸形是常见的先天畸形,约占所有胎儿畸形的7.35%,产前超声检出率差异较大, Carrera等报道胎儿消化系统畸形的产前超声检出率为81%,而Rydberg等报道其检出率仅为39%.孕周、羊水量、检查方法、对消化系统畸形的认识等可能影响产前超声对胎儿消化系统畸形的检出率;同时胎儿腹内解剖结构较多,变异大,正确区分正常解剖变异与结构畸形以及细致全面的胎儿检查极其重要.目前,许多胎儿消化系统畸形的超声表现常常被误解,如肛门闭锁与肠管内径增宽的关系、胎儿肠管回声增强的临床意义、胃泡大小与食管闭锁的关系等;还有部分消化系统的异常如胎儿腹腔囊性或实性包块,确诊非常困难,也时时困扰着产前超声诊断医师.本文从胚胎发育、胎儿消化系统畸形超声特征、胎儿消化系统畸形产前超声诊断思路等进行详细阐述,供超声医师及产前咨询医师参考. |
