Post-Endovascular Thrombectomy Perfusion Imaging (CT and MR) as a Prognostic Biomarker and Patient-Selection Tool for Adjuvant Therapy: A Systematic Review, Meta-Analysis, and Clinical Threshold Framework.
BACKGROUND AND PURPOSE Despite high rates of macrovascular recanalization, approximately half of patients with large vessel occlusion stroke fail to achieve functional independence after endovascular thrombectomy (EVT). Residual tissue-level perfusion abnormalities - detectable on post-procedural CT perfusion (CTP) - h...
