Hypoperfusion Intensity Ratio Less Than 0.4 Is Associated with Favorable Outcomes in Unsuccessfully Reperfused Acute Ischemic Stroke with Large-Vessel Occlusion
In unsuccessfully reperfused patients with AIS-LVO, an HIR of <0.4 is associated with favorable outcomes, emphasizing on the importance of robust collateral circulation. This finding suggests that perfusion imaging and HIR evaluation could guide clinical decision-making and prognostication in this challenging patient subset.
