Prenatal Diagnosis of the Fetal Retroesophageal Left Brachiocephalic Vein: Case Series and Review of the Literature
JOURNAL OF ULTRASOUND IN MEDICINE(2020)
摘要
A retroesophageal left brachiocephalic vein (LBCV) is a highly rare anomaly. We retrospectively analyzed 7 cases of a retroesophageal LBCV that were prenatally diagnosed from a database of fetal echocardiogram of 31,356 cases. The 3-vessel view and the long-axis view are the main views for confirming a fetal retroesophageal LBCV. An isolated retroesophageal LBCV is rare, and it is typically associated with congenital heart defects, especially conotruncal defects and a right aortic arch. An isolated fetal retroesophageal LBCV has a good prognosis and does not need surgical treatment.
