Brachiocephalic vein (Vena brachiocephalica)
Educational content only — not medical advice.
Anatomy
Formed behind the sternoclavicular joint by internal jugular and subclavian confluence; the right is short and near-vertical, the left long and oblique crossing the mediastinum in front of the brachiocephalic trunk and arch, together forming the SVC.
Clinical notes
Central lines from the subclavian route risk puncturing it into mediastinal air; left-sided aneurysmal arch compression gives positional facial plethora on lying down.
