产前超声诊断异位心胎儿七例回顾性分析

Retrospective analysis of prenatal ultrasound diagnosis of 7 cases with ectopia cordis

目的探讨胎儿异位心的产前超声诊断方法。方法对产前超声诊断为异位心的胎儿进行了回顾性分析,运用系统产科超声检查方法详细检查每一例胎儿,发现本病者行详细的胎儿超声心动图检查。结果产前超声诊断并经产后确诊的胎儿异位心7例,其中仅1例为单纯胸外异位心,6例(6/7)合并心外畸形,包括Cantrell五联征4例,脊柱侧突畸形3例,唇腭裂2例,无脑畸形1例。7例中5例(5/7)伴发心内严重结构畸形。结论产前超声检查是诊断胎儿异位心的可靠手段。

Objective To explore prenatal diagnosis of fetal ectopia cordis by ultrasound. Methods A total of seven fetuses with ectopia cordis, who were diagnosed with prenatal ultrasound from 2000 to 2008, were included in the study. The fetal echocardiography was performed when ectopia cordis was suspected. Results The seven cases with ectopia cordis were prenatally diagnosed. Only 1 case was ectopia cordis. The remain 6 cases （ 6/7 ） were extra-cardiac malformations including 4 cases with pentalogy of cantrell, 3 with scoliolosis, 2 with cleft lips and palate, 1 with anencephaly. Six of the 7 cases （ 6/7 ） had severe intraeardiac structural malformations. All cases were postnatally diagnosed. Conclusions The ultrasound of prenatal assessment is helpful for diagnosis of fetal ectopia cordis.
