Figure 3: A 57-year-old man presented with left hemiparesis for 2 h, with favorable outcome after successful mechanical thrombectomy. Axial NCCT brain at ganglionic level (a) and supraganglionic level (b) showed hypodense area at right MCA cortex lateral to the insular ribbon (M2), and at the superior territory of the right lateral MCA (M5); NCCT-ASPECTS was 8 points. CTA brain axial (c) and coronal (d) images showed filling defect along cavernous and supraclinoid parts of right ICA, and the M1 and M2 segments of right MCA (red arrow). CTP brain at ganglionic level (e-h) and supraganglionic level (i-l) showed mismatch area between CBV (f and j) and MTT (h and l) at rightfrontoparietal area. (CTP-ASPECTS at 50% cut point: CBF-ASPECTS = 1, CBV-ASPECTS = 8, TTP-ASPECTS = 0, MTT-ASPECTS = 1; CTP-ASPECTS at 75% cut point: CBF-ASPECTS = 2, CBV-ASPECTS = 9, TTP-ASPECTS = 4, MTT-ASPECTS = 6). Cerebral angiogram AP view of right CCA pre-IAT (m) showed total occlusion at right carotid bulb and M1 segment of right MCA. AP view of right ICA post-IAT (n) showed recanalization of the right carotid bulb and M1 segment of right MCA. TICI 2b was achieved, and the patient's mRS score at 3 months was 1 point. NCCT – Noncontrast computed tomography; CTP – Computed tomography perfusion; CTA – Computed tomography angiography; MCA – Middle cerebral artery; TTP – Time to peak; CBF – Cerebral blood flow; IAT – Immunoaugmentative therapy; ASPECTS – Alberta stroke program early computed tomography score; MTT – Mean transit time; AP – Anteroposterior
