Left brachiocephalic vein, also known as innominate vein runs in upper mediastinum posterior to the thymus and anterior to the transverse aortic arch and aortic branches. LBCV can be visualized on gray scale as well as color Doppler ultrasound at the level above the 3 vessel view. This is the first Indian study to demonstrate the significance of its routine visualization and its measurements on prenatal ultrasound. Isolated intrathymic LBCV is a normal variant and in isolation does not warrant an alteration in routine management of pregnancy. Absent LBCV or dilated LBCV are pathological and warrant a thorough anomalies scan and fetal echocardiography.
