【摘要】：目的评价二维超声心动图(2DE)与2DE联合时空关联成像(STIC)技术在胎儿先天性心脏大动脉畸形的诊断价值。方法选择我院可疑有胎儿心脏大动脉畸形175例孕妇,先行2DE后,在2DE基础上联合STIC成像技术,以胎儿心尖四腔心切面及主动脉弓长轴切面作为初始采集图像,结合多平面成像模式(MPR)、超声断层成像模式(TUI)、表面成像等进行脱机离线分析进行诊断。最终诊断以病理尸检、出生后行新生儿2DE或心外手术结果为准。对比2DE与2DE联合STIC技术在胎儿先天性心脏大动脉畸形检查的准确度。结果 175例可疑心脏大血管畸形胎儿,其中9例(5.1%)失访,在166例产前诊断病例中,患有心脏大动脉畸形41例(24.7%),其中22例胎儿终止妊娠并尸检,10例产后手术证实,9例行心脏超声检查并长期随访证实。2DE正确诊断大动脉畸形33例,8例未正确诊断,2DE联合STIC成像正确诊断大动脉畸形40例,1例未正确诊断,2DE与2DE联合STIC技术在诊断胎儿心脏大动脉畸形符合率分别为95.2%和99.4%,差异有统计学意义(χ2=4.111,P=0.043)。结论 STIC技术对胎儿心脏大动脉畸形诊断具有独特优势,2DE联合STIC技术可以获得更加准确的诊断信息。
[Abstract]:Objective to evaluate the combination of two dimensional echocardiography (2DE) and 2DE in combination with space-time intersecting imaging (STICI). Methods 175 pregnant women with suspected malformation of fetal great cardiac artery were selected. After 2DE, combined with STIC imaging technology, fetal apical quadrilateral incisor and long axis of aortic arch were taken as the initial acquisition images, combined with multiplanar imaging mode. Ultrasound tomography mode TUI, surface imaging and other offline analysis were performed to diagnose. Finally, pathological autopsy was used for diagnosis. The accuracy of 2DE and 2DE combined with STIC in the examination of fetal congenital cardiac artery malformation was compared. 175 cases of suspected heart macrovascular malformation fetus. Of 166 cases of prenatal diagnosis, 41 cases were suffering from cardiac artery malformation, 22 of them had fetal termination and autopsy. 10 cases were confirmed by postpartum operation, 9 cases were diagnosed by echocardiography and followed up for a long time, 33 cases were diagnosed correctly by .2DE, 8 cases were not correctly diagnosed. 2DE combined with STIC imaging was used to correctly diagnose 40 cases of great artery malformation and 1 case was not correctly diagnosed. The coincidence rates of 2DE and 2DE combined with STIC were 95.2% and 99.4 respectively in the diagnosis of fetal cardiac artery malformation. The difference was statistically significant (蠂 2 4.111). Conclusion STIC technique has a unique advantage in the diagnosis of fetal cardiac artery malformation. 2DE combined with STIC technique can obtain more accurate diagnostic information.
