目的 评价时空关联成像(spatio-temporal image correlation,STIC)在诊断胎儿复杂心脏畸形中的应用价值.方法 选择二维超声筛查疑似复杂心脏畸形的25例中晚孕期胎儿,胎龄20～30周,平均(25.88±8.3)周.进行心脏和胸部的自动扫查,应用STIC技术后处理获得动态三维图像,对获得的容积数据应用正交三平面模式、表面成像模式、反转模式和最小模式离线分析进行心脏复杂畸形的诊断,并与尸解或出生后彩色多普勒超声复查的结果对照分析.结果 25例胎儿通过STIC技术均可获得满意的胎儿心脏容积数据.发现胎儿复杂心脏畸形中.右室双出口1例,永存动脉干1例,完全型大动脉转位3例,矫止型大动脉转位1例,完全性心内膜垫缺损4例,右室发育不良1例,左室发育不良2例,三尖瓣闭锁1例,肺动脉闭锁1例,法洛四联症3例,单心房1例,两腔心畸形4例,法洛五联症1例,房间隔缺损、室间隔缺损并冠状静脉窦扩张1例.23例与尸体解剖或产后复查结果相一致,敏感性为92%(23/25).结论 STIC技术能快速准确地检测出胎儿复杂心脏畸形,对妊娠预后具有重要的指导意义.

Objective To evaluate the value of spatio-temporal, image correlation (STIC) in prenatal diagnosis of complex heart malformations.Methods STIC was used to examine 25 fetuses with 20-30 weeks of gestation who were doubted with complex heart malformations prospectively by two-dimensional (2D) echocardiography.Dynamic three-dimensional imaging was achieved by postprocessing technique with STIC across the entire fetal heart and thorax.An offline analysis of the acquired volume was carried out to examine the fetal cardiac anatomy with multiplanar mode, surface rendering and minimum mode.The results of prenatal diagnosiswere compared with postnatal color Doppler and surgical findings.Results Successful STIC volume datasets were obtained in all 25 fetuses.The findings of all 25 fetus with complex heart malformations included double outlet of right ventricle in 1 case, truncus arteriosus in 1 case, complete transposition of the great arteries in 3 cases,corrected transposition of the great arteries in 1 case, complete endocardial cushion defect in 4 cases, hypoplastic right ventricle syndrome in 1 case, hypoplastic left heart syndrome in 2 cases, tricuspid atresia in 1 case,pulmonary atresia in 1 case, tetralogy of Fallot in 3 cases, single atrium in 1 case, single atrium and single ventrium in 4 cases,in 1 case, atrial septal defect and ventricular septal defect with coronary sinus dilatation in 1 case.The major diagnoses derived from STIC in 23 of 25 cases were consistent with the results of postnatal color Doppler and surgical findings.Conclusions STIC can provide more accurate information of structures of complex fetal heart malformations and has great value in pregnant prognosis.
