Functional outcomes at 90 days according to the mRS score. Distribution of 90-day mRS scores in patients with complete (mTICI 3) versus mTICI 0–2b reperfusion (A) and success of reperfusion (mTICI 2b–3) versus mTICI 0-2a (B). Scores range from 0 to 6, with higher scores indicating greater disability.

Table 1:

Angiographic and clinical outcomes^{^a}

Outcomes	No.	Values
Successful reperfusion (mTICI 2b–3)	110	90 (81.8)
Complete reperfusion (mTICI 3)	110	67 (60.9)
Onset to successful reperfusion (median) (IQR) (min)^{^b}	90	455 (340–570)
Groin puncture to successful reperfusion (median) (IQR) (min)	90	45 (22–70)
No. of passes (median) (IQR)	110	1 (1–2)
Re-occlusion	110	6 (5.5)
Procedural complications	110	20 (18.2)
Dissection^{^c}		13 (11.8)
Embolization		8 (7.3)
Vasospasm		2 (1.8)
Growth of infarct core	110	35 (31.8)
Any ICH	110	13 (11.8)
sICH	110	3 (2.7)
Favorable outcome (90-day mRS 0–2)	110	35 (31.8)
Poor outcome (90-day mRS 3–6)	110	75 (68.1)
90-Day all-cause mortality	110	45 (40.9)

Note:—ICH indicates intracranial hemorrhage.
↵a Values are No. (%) unless otherwise as indicated.
↵b Data among patients with successful reperfusion.
↵c Involved V1 segment (n = 1), V3 segment (n = 3), V4 segment (n = 3), and basilar artery (n = 6).

Independent predictors of favorable outcome^{^a}

Note:—– indicates not available.
↵a ORs were calculated using a backward-stepwise multivariable penalized-likelihood logistic model. Candidate predictors in model 1 were mothership, admission to intensive care, atrial fibrillation, pretreatment NIHSS, pretreatment ASPECTS, pretreatment DWI BSS, IV thrombolysis, PcomA collateral flow, thalamus involvement, and onset-to-groin puncture time. Candidate predictors in model 2 were mothership, admission to intensive care, atrial fibrillation, pretreatment NIHSS, pretreatment PC-ASPECTS, pretreatment DWI BSS, IV thrombolysis, PcomA collateral flow, thalamus involvement, onset-to-groin puncture time, and complete recanalization (mTICI 3).
