Severe Vasospasm of the Middle Cerebral Artery after Mechanical Thrombectomy Due to Infective Endocarditis: An Autopsy Case.

Untreated infective endocarditis (IE) often produces infective emboli in major cerebral arteries. We describe a case of middle cerebral artery occlusion due to IE, which caused severe vasospasm and reocclusion after mechanical thrombectomy (MT). We present the pathologic findings of the occluded middle cerebral artery and investigate the precautions to be taken while performing MT due to IE.
