摘要
目的:探讨胎儿期心内膜垫缺损(ECD)的超声特征,分析诊断中存在的问题,以提高其产前超声诊断率。方法:对所有受检胎儿均行四腔心切面及四腔心平面头侧偏转法获得左、右室流出道、主动脉长轴切面、心底短轴切面及三血管切面扫查,再延降主动脉上行检测主动脉弓切面、动脉导管弓切面。对产前诊断的11例心内膜垫缺损的胎儿期超声心动图及相关超声信息进行总结分析。结果:共诊断胎儿心内膜垫缺损11例,均经引产后解剖证实或出生后超声证实。其中完全型ECD8例,部分型ECD3例。早期误诊1例,后于妊娠中期纠正诊断。结论:本资料结果显示,心内膜垫缺损产前有特征性的超声诊断声像,并依此征象可将其检出。ECD多合并严重的大血管畸形和心外畸形或染色体异常,所以大血管畸形、心外畸形、染色体异常的检出也是非常重要的。在胎儿ECD的产前诊断中仍然存在误诊、诊断时间过晚等问题,值得引起注意。
Objective To evaluate the sonographic feature of endocardial cushion defect （ECD） in fetus, also analyze the problems and improve diagnostic ratio of this kind of defects. Method The prenatal uhrasonographie characterlstics, postnatal corpse anatomy, their complicating anomalism and results were analyzed retrospectively in 11 cases with fetal ECD. All patients were referred for fetal echocardio- graphy, including four-chamber, outflow tract, three vessels and short -axis views, then the aortic arch and ductal arch long -axis views. We reviewed the fetal sonograms and medical records of 11 fetuses with prenatal diagnosis of cndocardial cushion defect. Results There were 11 cases with fetal ECD which were finally diagnosed by postnatal anatomy or sonogram, including 8 cases with complete ECD and 3 cases with partial ECD. 1 case had misdiagnosis in early time, but corrected in mid - half pregnancy. Conclusion The results show that the prenatal ultrasound diagnosis of congenital ECD can be made according to their typical uhrasonographic characteristics and ECD usually combined with great arteries or extra cardiac anomalies, some with abnormal chromosome. Although prenatal ultrasonic screening for ECD has many virtues, misdiagnosis and too late diagnosis should be pay attention to.
