Rare case of persistent left superior vena cava to left upper pulmonary vein: pathway for paradoxical embolization and development of transient ischemic attack and subsequent occlusion with an amplatzer vascular plug.

Abstract

We report the successful transcatheter closure of a large persistent left superior vena cava draining into a left upper pulmonary vein in a patient who suffered 2 transient ischemic attacks after intravenous (IV) injection of saline flush solution into a left arm peripheral IV line utilizing an Amplatzer Vascular Plug.
