Characteristics and outcomes of subarachnoid hemorrhage from vertebral artery dissection: A comparative study with other non‐traumatic etiologies

Description
Summary:Aim Vertebral artery dissection (VAD) is a rare cause of non‐traumatic subarachnoid hemorrhage (SAH) with significant clinical implications. This study compared the clinical characteristics and outcomes of SAH from intracranial VAD rupture to those from other etiologies, primarily aneurysmal rupture. Methods This single‐center retrospective cohort study at Okayama University Hospital included patients with non‐traumatic SAH diagnosed between 2019 and 2023. Patients were categorized into “VAD rupture” and “other etiologies” groups. The main outcome was clinical presentation and symptoms. Additional outcomes included ICU mortality, in‐hospital mortality, and unfavorable outcomes at discharge and 6 months, defined as a modified Rankin Scale score of 3–6. Results A total of 66 patients were included, with 14 in the VAD rupture group and 52 in the other etiologies group. The VAD rupture group was younger (median age 49 vs. 64 years, p = 0.003) and had a higher incidence of out‐of‐hospital cardiac arrest (42.9% vs. 9.6%, p = 0.011). Preceding headache was more common in the VAD rupture group (78.6% vs. 11.5%, p
