Abnormalities of the left brachiocephalic vein (LBCVA)

Abnormalities of the left brachiocephalic vein (LBCVA) Normal LBCV originates from the joining of the left jugular and subclavian veins and crosses obliquely the upper mediastinum, anteriorly to the branches of the aortic arch and dorsally to the thymus, to join the vertical right brachiocephalic vein RASopathies, 22q11 microdeletion syndrome, trisomy 21, 8p duplication and deletion, 16p12.2 microdeletion Prenatal incidence of LBCV is 0.4% Abnormal course of the LBCV occurred in 35.1% of cases (retroesophageal, subaortic, intrathymic) Exact prevalence of this venous anomaly is rare Subaortic and retroesophageal courses are associated with conotruncal anomalies Routine identification of the LBCV in the 3VT view of the upper mediastinum in prenatal ultrasound could help to improve the detection of other CHD, particularly, in the case of the retroesophageal or subaortic course For further quires please contact Dr Ashutosh Foetal & Genetic Clinic; E 874, Chittaranjan Park, New Delhi 110019 Mail – [email protected]; Contact – 9953728760
