A 36-year-old woman was presented with left hemiparesis. Her NIHSS was 13 points at the time of admission to our hospital. A brain MRI detected an occlusion of the right middle cerebral artery, and a heart echocardiogram identified vegetation on the mitral valve. She was diagnosed with middle cerebral artery occlusion due to infective endocarditis and underwent mechanical thrombectomy (MTB). Despite the occurrence of extravasation from the middle cerebral artery during the mechanical thrombectomy, thrombolysis in cerebral infarction Grade 3 (TICI3) was achieved. The whitish embolus material gotten during surgery was submitted for pathological examination. Following the operation, she developed acute heart failure due to severe mitral regurgitation, accompanied by cardiogenic and septic shock. On day 19 post admission, open heart surgery was performed, and she was later discharged from our hospital at her mRS0. We suggest that early diagnosis and treatment of IE, safe MTB, and cooperation with other departments are important factors for good patient outcomes.
