摘要
目的 探讨无脾综合征胎儿的超声声像图及尸解特征。方法 在48186例孕16-40周的胎儿系统超声检查中，发现胎儿心脏畸形88例，其中超声检查及尸解确诊4例无脾综合征，回顾性分析4例无脾综合征胎儿的超声声像图及尸解资料。结果 胎儿无脾综合征超声声像图及尸解特点为：（1）复杂而严重的心脏及大血管畸形（永存动脉干、心内膜垫缺损及单心室等）；（2）内脏转位；（3）脾脏缺如；（4）对称性发育倾向（双侧3叶肺、肝左右叶大小对称、双上腔静脉等）。结论 产前系统胎儿超声检查发现胎儿有复杂心血管畸形时，应常规观察胎儿脾脏及内脏位置，以早期诊断胎儿无脾综合征。
Objective In order to understand the basic characteristics, uhrasonographic diagnosis and postnatal pathology of four fetal asplenia syndromes were reviewed. Methods In 48 186 cases （ from Jan 1999 to Oct 2004 ） , systematic fetal uhrasonography and fetal echocardiography were performed at gestational age of 16-40 weeks. The data showed that 88 cases were diagnosed as congenital heart diseases. Among them 70 cases were confirmed by postnatal pathology, and 4 cases were confirmed as asplenia syndrome. The systematic fetal uhrasonography and postnatal pathology of four fetal asplenia syndromes were analyzed retrospectively. Results The uhrasonographic features and pathological characteristics of fetal asplenia syndrome were ： （ 1 ） Severe and complicated cardiac anomalies （ persistent truncus arteriosus, endocardial cushion defect, single ventricle etc. ） ; （ 2 ） Situs inversus viscerum ; （ 3 ） Splenic agenesis were not found ; （4） Predominant left-side： a fetus whose left side was a mirror of its right side （ trilobated lungs, decrease in the normal size difference between the right and left lobe, bilateral superior vena cava）. Conclusions The results suggested that we should detect the position of fetal spleen and abdomen when complicated anomalies were present, in order to get early diagnosis of fetal asplenia syndrome.
