| 目的 探讨超声断层显像(TUI)技术在分析胎儿心脏大动脉位置关系中的应用价值。方法 采用TUI法分析胎儿心脏的容积数据,在相邻的2个层面上分别显示肺动脉瓣和主动脉瓣,利用正交点标记肺动脉瓣的位置,分析主动脉瓣的相对方位。结果 12例大动脉转位中,7例合并"单心室",TUI显示其中5例主动脉瓣位于肺动脉瓣右前方,其余2例分别位于肺动脉瓣正前方和左前方;其余可显示四腔心切面的5例中,3例主动脉瓣位于右前,2例主动脉瓣分别前方合正上方。13名正常胎儿心脏,TUI均可显示主动脉瓣均位于肺动脉瓣右后方。结论 采用TUI法可以简便、准确地判断大动脉的位置关系。 |

| Objective To assess the value of tomographic ultrasound imaging (TUI) for prenatal analysis of the relative orientation of fetal heart and great arteries. Methods Volume datasets acquired from 12 patients of transposition of the great arteries (TGA) and 13 normal fetal heart were evaluated offline with TUI. The aortic valves (AV) and pulmonary valves (PV) were respectively showed on the two parallel slices. According to the pivot point in the middle of the PV in one slice, the relative orientation of the AV on another slices were analyzed. Results In the 12 patients of TGA confirmed postnatally, 7 were concomitant with single ventricle anomaly, AV was on the anterior-right orientation of the PV in 5, and was relatively on the anterior and anterior-left orientation in other 2 of them.In the remained 5 with seeming normal 4 chamber view, AV was found on the anterior-right of the PV in 3, and was relatively on the anterior and upright orientation.in other 2 patients. In 13 normal fetuses, TUI showed that all AV located on the posterior-right orientation to the PV. Conclusion TUI can provide detailed spatial information of the great arteries both in normal and abnormal fetal heart. It may be a convenient and veracious tool for prenatal exploring the morphology of the great arteries. |
