摘要
目的探讨产前超声在诊断胎儿孤立性左位心中的临床应用价值。
方法回顾性分析2000－2016年湖南省3个产前诊断中心诊断为孤立性左位心的38例胎儿的超声特点及伴随的心内外畸形。
结果38例孤立性左位心胎儿中，19例左异构，14例右异构，5例未归类。心内外畸形总体发生率为97.4%，左异构与右异构分别为94.7%和100%。先天性心脏病（先心病）总体发病率为92.1%，左异构与右异构分别为84.2%和100%，其中最常见的是右室流出道梗阻、功能性单心室及房室间隔缺损。肺静脉异位引流常见于右异构患者。心外畸形中最常见的是肠旋转不良，发生率为86.9%。下腔静脉离断及多脾常见于左异构患者，下腔静脉与腹主动脉同侧并行排列及无脾常见于右异构患者。
结论胎儿孤立性左位心十分罕见，却具有极高的心内外畸形发生率。
ObjectiveTo investigate the clinical application valve of prenatal ultrasound in diagnosis of fetal isolated levocardia（IL）.
MethodsThirty-eight IL fetuses diagnosed in three prenatal diagnosis centers from 2000 to 2016 were reviewed with their prenatal ultrasound features and cardiac and extracardiac malformations.
ResultsThirty-eight IL cases included 19 cases of left isomerism（LI）, 14 cases of right isomerism（RI） and 5 non-classified cases. The overall incidence of malformations in IL patients was 97.4% with 94.7% in LI patients and 100% in RI patients. The incidence of cardiac malformations was 92.1% with 84.2% in LI patients and 100% in RI patients. The most common congenital heart diseases were： right ventricle outlet obstruction, univentricular physiology and atrioventricular septal defect. Anomalous pulmonary venous connection was more commonly seen in LI patients than in RI patients. The most common extracardiac malformation was duodenal obstruction（86.9%）. Inferior vena cava interruption and polysplenia were more commonly seen in LI patients.Juxtaposition of aorta and inferior vena cava and asplenia were more commonly seen in RI patients.
ConclusionsIL is very rarely seen in population with high incidence of congenital heart diseases and extracardiac malformations.
