Prenatal ultrasonic diagnosis of fetal coronary artery compensatory dilatation / 中国医学影像技术

ABSTRACT

Objective: To explore the value of prenatal ultrasound in diagnosis of coronary artery compensatory dilatation (CACD). Methods: Data of 17 CACD fetuses confirmed with echocardiography after birth or autopsy after labor induction were retrospectively analyzed. The ultrasonic features were observed, and the pregnancy outcomes were followed up. Results: CACD involved left and right CA in all 17 fetuses, 15 were diagnosed in late pregnancy and 2 in middle pregnancy, all accompanied with hemodynamic abnormalities, including 10 with different degree fetal edema and 7 with Galen venous aneurysm. Fetal growth restriction and other structural abnormalities were observed each in 8 fetuses. Among 17 fetuses, induced labor was performed in 8, intrauterine fetal death occurred in 3, whereas 6 born through emergency cesarean section, including 2 premature died within 1 week after birth and 4 full-term healthy newborns. Conclusion: Prenatal ultrasound can be used to diagnose fetal CACD and early warning fetal intrauterine hypoxia.
