| 中文摘要: |
| 圆锥动脉干畸形(CTD)是由于圆锥动脉干段胚胎发育异常所致。22q11.2微缺失综合征与CTD的发生密切相关,遗传学技术的进展使其产前诊断成为可能。超声心动图是小儿心脏影像无创检查的首选方法。MSCT、MRI可很好地显示心外大血管。心血管造影虽是一种有创检查手段,但其在体、肺动脉等的显影中具有不可替代的作用。目前,上述技术所得结果仍有分歧,而制定一种统一的诊断标准是提高其诊断正确性的关键所在。 |
| 英文摘要: |
| Conotruncal defects (CTD) are related to abnormal division or rotation of the primitive truncus during embryologic development. New cytogenetic techniques, such as Fish analysis, make it possible for the prenatal diagnosis of the 22q11.2 microdeletion syndrome, which has a high frequency with the CTDs. While the echocardiography continues to be the first choice of the non-invasive diagnosis methods, the MSCT and cardiac MRI can have a good imaging of the extracardiac thoracic vessels in children with CTDs. Though angiocardiography in invasive, it still plays an important and irreplaceable role in the full view of systemic and pulmonary arterial. This article reviews the progress and the clinical application of those methods in the conotruncal anomalies. There are differences among the result of the techniques above, and the establishment of an identical criterion for the CTDs is the key to improve the accuracy of the diagnosis. |
