Notes: Abbreviations: ASPECTS: Alberta Stroke Program Early CT Score; car-T: carotid terminus; HTN: hypertension; ICA: internal carotid artery; IV rtPA: intravenous recombinant tissue plasminogen activator; L: left; M: male; MCA: middle cerebral artery; mo: months; mRS: modified Rankin Scale score at 90 days; NIHSS: National Institutes of Health Stroke Scale; OTP: time from onset of stroke to groin puncture; R: right; sICH: secondary intracerebral hemorrhage; T2DM: type 2 diabetes; TICI: Thrombolysis in Cerebral Infarction.

Footnote: Regarding Case 4, the patient fell and sustained scalp laceration at admission. It was determined that rtPA was better not to be administered. Instead, the patient underwent thrombectomy procedure directly. An intracranial hemorrhage was detected on the MRI conducted 24 h after treatment, likely resulting from a hyperperfusion injury. Intracerebral hemorrhage was not found at presentation.
