Figure 1. Example of a TMM+, Recanalized Patient.

(A) A 15-year-old boy presented 1.5 hours after last known well with NIHSS 25. Imaging notable for left M1 occlusion with a favorable mismatch ratio of 3.0. (B) Moderate-sided DWI lesion on initial imaging. (C) After TICI 2b reperfusion, final stroke volume seems similar to initial; mRS 0, PSOM 0 reported at follow-up. Abbreviations: DWI = diffusion-weighted imaging; mRS = modified Rankin Scale; TMM = target mismatch.
