Popis:	Aim To establish an artery and venous sinus occlusion image score (AVOIS) which is compatible in both cerebral arteries and venous system diseases. Methods A total of 188 consecutive patients with the final diagnosis of anterior circulation infarct (ACI) and 56 consecutive patients with cerebral venous and sinus thrombosis (CVST) were retrospectively studied. The AVOIS was developed based on the severity of occlusive changes of main intracranial arteries and venous sinuses (present = 0, partial occlusion = 1, absent = 2), and divided into four groups (CVST group: 0, 1‐5, 6‐10, >10. ACI group: 0, 1‐5, 6‐10, >10) arbitrarily. A receiver operating characteristic (ROC) curve was applied to discover the sensitivity and specificity of AVOIS. The National Institutes of Health Stroke Scale (NIHSS), Clot Burden Score (CBS) were set as the reference. Logistic regression models were developed to adjust for baseline clinical variables and AVOIS. Length of hospital stay (LOS) was also evaluated using the Kaplan‐Meier estimator. Results For the CVST group, a positive correlation between AVOIS and NIHSS was discovered (Spearman's ρ = 0.54, p A novel score system called the Artery and Venous Sinus Occlusion Image Score (AVOIS) was developed based on quantification analysis of the intracranial thrombus in both artery and venous sinus (Table 1). According to the CTA or MRA, anterior circulation and venous sinuses were allotted different scores (present = 0, partial occlusion = 1, absent = 2) by researchers. The total score on AVOIS in anterior circulation or venous sinus was accumulated to 14 points.
