We report a 76-year-old man with paradoxical cerebral air embolism. He developed consciousness disturbance and left hemiparesis after a postural change in rehabilitation. CT showed multiple air densities within the right hemisphere. An echocardiography showed a large right-to-left (RL) shunt. We considered the reason to be that a small amount of air entered, and the Valsalva-like maneuver with the postural change moved air into arterial circulation through the RL shunt and embolized a brain artery. The present case showed that even a small amount of air in the venous circulation may become a potential risk for cerebral air embolism, especially in the presence of a large RL shunt.

D016893 Carotid Stenosis Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).

D019320 Embolism, Paradoxical Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.
