Clinical outcomes of endovascular treatment for acute basilar artery occlusion patients with extremely severe symptoms.

ABSTRACT:

Objective

This study aimed to investigate the effectiveness and safety of endovascular treatment (EVT) in acute basilar artery occlusion (ABAO) patients with extremely severe symptoms [National Institutes of Health Stroke Scale (NIHSS) score >25] in the real world.

Methods

This study was a subgroup analysis of a prospective multicenter cohort study (EVT for Acute Basilar Artery Occlusion Study, BASILAR registry). Patients were categorized into EVT and standard medical treatment (SMT) groups. The primary effectiveness outcome was the distribution of modified Rankin Scale (mRS) scores at 90 days.
