  • Note:—Recanalizers = arterial occlusive lesion (AOL) 3 recanalization, ie, full recanalization; nonrecanalizers = AOL 0–2 recanalization, ie, partial or null recanalization. Univariate statistical analysis comparing recanalizers versus nonrecanalizers. Student t test or Fisher exact test for comparison of percentages. Results are expressed as mean (standard deviation), ratio, or percentages. mRS indicates modified Rankin Scale; DWI Vol, volume of lesions detected on DWI.
