Abstract Objective: To investigate the clinical value of fetal echocardiography in prenatal diagnosis of vascular ring. Methods: Ultrasound images and follow-up results of 8 fetuses with vascular ring were retrospectively analyzed and summarized. Results: Double aortic arch formed “O” shaped complete vascular ring in 2 cases. Right aortic arch, left ductus artery and aberrant left subclavian artery formed “U” shaped complete vascular ring in 5 cases. Left aortic arch and aberrant right subclavian artery formed “C” shaped incomplete vascular ring in one case. Conclusion: Fetal echocardiography is of great clinical value in prenatal diagnosis of vascular ring. Three vessels and trachea view is the most important for prenatal ultrasonic diagnosis of fetal vascular ring. Tracheal bifurcation coronal view and long axial of aortic arch view is auxiliary view. The above views may make accurate diagnosis for the different types of fetal vascular ring.
