Correlation between P2-PCA Volume Flow Rate and BOLD Cerebrovascular Reactivity in Patients with Symptomatic Carotid Artery Occlusion

This correlation suggests that impaired BOLD-CVR is partly linked to an increased PCA-P2 volume flow rate, potentially indicating the activation of leptomeningeal collaterals in severe hemodynamic conditions. Both imaging techniques could aid clinicians in creating personalized treatment strategies for patients with symptomatic ICA occlusion.
