Ruptured intracranial aneurysm with spontaneous occlusion of internal carotid artery: clinical characteristics, prognostic risk factors, and survival analysis.

ABSTRACT:

Background

Ruptured intracranial aneurysm (RIA) combined with internal carotid artery occlusion (ICAO) is a rare and serious vascular condition. We aimed to describe the clinical characteristics and outcomes of these patients.

Methods

We retrospectively analyzed cases of RIA with concurrent spontaneous ICAO from the Chinese Multicenter Aneurysm Database (CMAD). Logistic regression analysis was used to identify independent risk factors associated with patient prognosis. Cox proportional hazards model was performed to determine predictors of cumulative mortality.

Results

We analyzed 52 cases of RIA with ICAO, including 41 unilateral and 11 bilateral cases. Among unilateral ICAO cases, aneurysms were ipsilateral in 8, contralateral in 16, and midline in 17. Treatment inc
