Transverse continuous scanning on multiple sections above three vessels and trachea view in prenatal ultrasonic diagnosis of fetal cardiovascular anomalies / 中国医学影像技术

ABSTRACT

Objective: To explore the value of transverse continuous scanning on multiple sections above three vessels and trachea view in prenatal ultrasonic detection of fetal cardiovascular anomalies. Methods Using transverse continuous scanning on multiple sections above three vessels and trachea view, 502 normal fetus and 521 abnormal fetuses were observed, and ultrasonographic features of multiple sections above three vessels and trachea view were recorded. Results: Four sections could be obtained by moving probe from the three-vessel tracheal section to the cephalic side of fetus. Section of three-vessel tracheal was firstly observed, then section of brachiocephalic vein which could show brachiocephalic vein and transverse aortic arch was screened, section of initial segment of brachiocephalic artery which could show the cross section planes of brachiocephalic artery, left common carotid artery and left subclavian artery was observed, and finally section of bilateral subclavian artery and subclavian vein which could show long axis planes of bilateral subclavian artery, bilateral subclavian vein and cross section of bilateral common carotid artery was screened. Multiple sections above three vessels and trachea view could be displayed by continuous scanning in all 502 normal fetuses. Among 521 ultrasonographic abnormal fetuses, 236 fetuses were found with abnormal brachiocephalic vein, 277 with abnormal brachiocephalic artery, 7 with abnormal pulmonary vein drainage at the heart and 1 with aortic arch at the neck. Conclusion: Transverse continuous scanning sections above three vessels and tracheal view are helpful for prenatal ultrasonic diagnosis of fetal cardiovascular anomalies.
