Risk score for cerebral venous thrombosis outcome

The Risk Score for Cerebral Venous Thrombosis Outcome is a prognostic index that aids in predicting the likelihood of poor outcomes in patients diagnosed with cerebral venous thrombosis (CVT). This scoring system is particularly useful in stratifying patients based on their risk profile, thereby guiding clinicians in tailoring appropriate therapeutic interventions and follow-up strategies. The primary components of this risk score include six variables, each assigned a specific point value. These variables are male gender, malignancy, coma, mental status disturbance, deep venous thrombosis, and intracranial hemorrhage. The total score is calculated by summing the points corresponding to each present variable, resulting in a score ranging from 0 to 9. The risk of poor outcome is directly proportional to the total score. A score of 0 corresponds to a 3% risk of poor outcome, while a score of 1 increases the risk to 10%. The risk further escalates to 23% for a score of 2, 24% for a score of 3, and is equal to or greater than 47% for scores of 4 and above. This risk stratification allows clinicians to identify patients at higher risk of poor outcomes, facilitating early intervention and potentially improving patient prognosis.
