摘要
目的:探讨高分辨率血流成像(HD-Flow)联合时间-空间复合成像(STIC)诊断胎儿肺动脉闭锁合并室缺(PA-VSD)的临床价值。方法:分析经胎儿超声心动图诊断的44例PA-VSD胎儿心脏二维、HD-Flow联合STIC图像,评估HD-Flow联合STIC在PA-VSD不同分型诊断中的效能,并探讨PA-VSD胎儿动脉导管内径与左、右肺动脉内径相关性。结果:HD-Flow联合STIC诊断44例PA-VSD,其中A型42例,C型2例。HD-Flow联合STIC能够清晰显示胎儿肺动脉及其分支血管及动脉导管血流;Pearson相关性分析表明A型动脉导管内径和左、右肺动脉内径均呈正相关(r=0.507、0.404,P<0.01)。结论:HD-Flow联合STIC能够明确诊断PA-VSD并分型,有较大的临床应用价值,A型PA-VSD胎儿动脉导管内径与左、右肺动脉内径存在正相关。
Objective:To investigate the clinical value of high-definition flow(HD-Flow)combined with spatiotemporal image correlation(STIC)in the diagnosis of fetal pulmonary atresia with ventricular septal defect(PA-VSD).Methods:The two-dimensional images and HD-Flow combined with STIC images of 44 PA-VSD fetuses diagnosed by fetal echocardiography were analyzed,so as to evaluate the efficacy of HD-Flow combined with STIC in the diagnosis of different subtypes of PA-VSD,the relationship between the inner diameter of PA-VSD fetal ductus arteriosus and the inner diameters of left and right pulmonary artery was studied.Results:HD-Flow combined with STIC diagnosis was performed in 44 cases,including 42 cases of type A and 2 cases of type C.HD-Flow combined with STIC can clearly display the fetal pulmonary artery and its branches and ductus arteriosus blood flow.Pearson correlation analysis showed that the A-type ductus diameter was positively correlated with the left and right pulmonary artery diameters(r=0.507,0.404,P<0.01).Conclusion:HD-Flow combined with STIC can clearly diagnose PA-VSD and classify it,which has great clinical application value.There is a positive correlation between the diameter of fetal ductus arteriosus and the diameters of left and right pulmonary artery in type A PA-VSD.
