cerebral embolism
Obstruction of cerebral blood vessels by embolic material during cardiac procedures.
Full Definition
Cerebral embolism is a serious complication of cardiac surgery where particulate matter, air bubbles, or thrombi travel to cerebral circulation causing vessel occlusion. Common sources include aortic atheroma, intracardiac thrombus, or air introduced during surgical manipulation. Prevention strategies include epiaortic scanning, careful de-airing techniques, and filtration systems. Recognition requires vigilant neurological monitoring and may manifest as stroke, cognitive dysfunction, or delayed neurological deficits.
Usage
Usage note: Distinguish from thrombosis (in-situ clot formation) versus embolism (traveling obstruction).
