目的 探讨空间-时间关联成像技术（STIC）的高分辨率仿真血流成像模式（HD live flow）在胎儿完全性血管环（CVR）诊断中的价值。方法 回顾性分析38例胎儿CVR的超声心动图特征，采集容积图像并用相关软件进行后期分析；对比分析产前超声诊断结果和出生后超声心动图或血管三维重建结果。结果 STIC-HD live flow技术共检出38例胎儿CVR，其中27例（71.1%）右位主动脉弓伴左锁骨下动脉迷走、左位动脉导管，形成“U”形环；8例（21.1%）双主动脉弓，形成“O”形环；3例（7.9%）镜面右位主动脉弓伴左位动脉导管（导管连接降主动脉）形成“U”形环。1例产前二维和彩色多普勒超声技术误诊为镜面右位主动脉弓，STIC-HD live flow技术修正诊断为双主动脉弓，产后超声心动图和CTA证实。结论 STIC-HD live flow技术直观立体地显示主动脉弓及头臂分支和动脉导管的空间位置关系，对诊断完全性血管环及明确其具体类型有重要临床价值。

Objective To explore the clinical application of high definition live flow imaging mode（HD live flow）of spatio-temporal image correlation technology（STIC）in fetal complete vascular ring（CVR）. Method Features of 38 cases with CVR were retrospectively analyzed. STIC-HD live flow volume data were collected. The ultrasonographic features were comparatively analyzed with postnatal echocardiography or computed tomography angiography. Results A total of 38 cases with CVR were diagnosed by STIC-HD live flow technology，among which twenty-seven cases(71.1%) of right aortic arch with aberrant left subclavian artery and left ductus arteriosus（LDA），eight cases（21.1%）of double aortic arch（DAA） and three cases（7.9%）of mirror right aortic arch（MRAA） with LDA connecting descending aorta were diagnosed. One case was misdiagnosed as MRAA by two-dimensional and color doppler echocardiography technology.However the diagnosis was revised to DAA by STIC-HD live flow technology and confirmed by postnatal echocardiography and CTA. Conclusions STIC-HD live flow technology can display spatial relationship between aortic arch and brachiocephalic artery and ductus arteriosus visually and intuitively.It is of great clinical value in prenatal diagnosis of fetal CVR and specific types.
