One instance of a patient with brain embolism occurring in the contralateral middle cerebral artery during the t-PA intravenous injection

Abstract

An 82-year-old woman was presented with left hemiparesis and was admitted to the hospital. The MRI scan revealed acute infarction in the right hemisphere. The MRA scan showed the occlusion of the right middle cerebral artery. Tissue plasminogen activator (t-PA) was administered intravenously to the patient 3.5 hours after the onset of the event. Left hemiparesis improved within 15 minutes of administering t-PA; however, right hemiplegia occurred 55 minutes later. The MRA showed the occlusion of the left middle cerebral artery. Emergent endovascular thrombectomy achieved the recanalization of the left middle cerebral artery. When treating with intravenous thrombolysis, we should prepare for the interventional treatment.
