The calculator in question is the Risk Score for Cerebral Venous Thrombosis Outcome. This scoring system is specifically designed for patients diagnosed with cerebral venous thrombosis (CVT), a rare form of stroke caused by a clot in the venous sinuses of the brain.
The clinical utility of this calculator is to predict the patient's outcome after CVT, including the likelihood of death or dependency. It takes into account various factors such as age, gender, coma, mental status disturbances, intracerebral hemorrhage, deep venous system thrombosis, central nervous system infection, and cancer.
The score helps clinicians to stratify patients based on their risk and guide treatment decisions. It can also be used to provide patients and their families with a prognosis, which can be helpful in making informed decisions about care.
There are no specific exclusion criteria for the use of this calculator. However, it should be noted that the score is less reliable in patients with incomplete data or those with rare causes of CVT not included in the score.
