Overview

We explore the predictive value of CT perfusion parameters (permeability surface area, cerebral blood flow, cerebral blood volume) and multiphase CT angiography (clot localization, leptomeningeal collaterals and dural sinuses morphology) in the development of malignant brain oedema in patients with acute proximal occlusion of the middle cerebral artery. Patients from the multicentre prospective study PROVE-IT (Precise and Rapid assessment of collaterals using multi-phase CTA in the triage of patients with acute ischemic stroke for IV or IA Therapy; n = 200) were analysed. Primary outcome was evaluated by midline shift ≥ 5 mm on a follow-up CT/MRI. A CBV threshold of 1.76 ml/100 g had the highest sensitivity and specificity of for the midline shift. There was no significant difference between the two groups in analysed CT perfusion parameters calculated for the entire ischemic region.

Key words:
acute ischemic stroke – brain oedema – CT perfusion – CTA angiography – dural sinuses
