Abstract

Cerebral venous air embolism (CVAE) is a very rare phenomenon, assumed to result from retrograde progression of air bubbles introduced into the venous circulation through central venous catheter manipulation or, less often, peripheral vein cannulation, although its precise pathophysiology remains to be completely understood.CVAE's clinical presentation can be varied, often mimicking acute stroke, and diagnosis can easily be established through a conventional brain-CT scan.Treatment must be initiated promptly by placing the patient in the Trendelenburg position and providing high concentration oxygen, intravascular volume expansion and other supportive measures as needed; hyperbaric oxygen therapy may be considered for selected patients.
