What Researchers Did
Researchers reported a rare case of cerebral air embolism following central venous catheter removal in a patient with pulmonary arteriovenous malformation.
What They Found
They found air bubbles in the internal carotid arteries and a pulmonary arteriovenous malformation (PAVM) on computed tomography after the patient experienced loss of consciousness. The cerebral air embolism was treated with hyperbaric oxygen and intravenous thrombolytic therapy, followed by transcatheter embolization of the PAVM.
Canadian Relevance
