AbstractWe report a 49-year-old woman who sustained ischemic stroke after central venous catheter removal. Brain computed tomography (CT) scan revealed air bubbles in the subarachnoid vessels. Contrast-enhanced chest CT and ultrasonography revealed a residual catheter track in the center of a jugular vein thrombus. A right-to-left shunt was confirmed by transthoracic echocardiography and transcranial Doppler with bubble contrast. The patient was ultimately diagnosed with a paradoxical cerebral air embolism through the residual catheter track in the thrombus. Rapid recognition, response, and prompt diagnosis are the most important factors in the successful treatment of such an embolism.Copyright © 2012 National Stroke Association.
