Association of Computed Tomography Perfusion Parameters with 90-Day Functional Independence After Endovascular Thrombectomy.

ABSTRACT: Background/Objectives: Recently, a novel CT perfusion (CTP) parameter, the compensation index (COMPI; ratio of 4 s delayed perfusion to 6 s delayed perfusion), was shown to correlate more strongly with digital subtraction angiographic collaterals than the cerebral blood volume index (CBVI) and hypoperfusion intensity ratio. Methods: We retrospectively analyzed all anterior circulation large vessel occlusion patients treated at multiple thrombectomy centers from January to December 2024 to determine the relationship of COMPI and other CTP parameters with the primary outcome: a 90-day modified Rankin Scale (mRS) score of 0-2. Univariable logistic regression was performed to assess the association between each CTP parameter and the primary outcome in the full cohort and in those
