超声早期诊断胎儿单心室、单心房、永存动脉干一例.

Fetal cardiovascular abnormalities, which coexists with complex and multi-malformation, are a key factor of neonatal mortality. Combination of multiple ultrasound imaging techniques before delivery can accurately diagnose fetal congenital cardiac malformations, make accurate classification and detect accompanying malformations, which is of great significance to offer proper prenatal consultation, evaluation, decision-making and post-birth treatment, so as to achieve the goal of eugenics. This article reports the clinical data of a case of early sonographic diagnosis of fetal single ventricle, single atrium, and persistent truncus arteriosus. The characteristic structural changes under ultrasound are observed to improve the technical level of ultrasound physician in diagnosing this disease, so that makes it possible to detect complex fetal abnormalities in the early and middle stages of pregnancy.
