CTP-Based Tissue Outcome: Promising Tool to Prove the Beneficial Effect of Mechanical Recanalization in Acute Ischemic Stroke

Purpose: To prove the tissue-protecting effect of mechanical recanalization, we assessed the CT perfusion-based tissue outcome (“TO”) and correlated this imaging parameter with the 3-month clinical outcome (“CO”). Materials and Methods: 159 patients with large intracranial artery occlusions revealing mechanical recanalization were investigated by CCT, CT angiography (CTA) and CT perfusion (CTP) upon admission. For the final infarct...
