Prediction of ventriculoperitoneal shunt dependency in patients with aneurysmal subarachnoid hemorrhage

Abstract

An FRI score created by discriminant function analysis can predict whether or not a permanent shunt is required, even if separate factors are not in agreement with each other or show a weak correlation when considered separately. An increased FRI score was strongly and linearly correlated with the risk of EVD challenge failure. A prospective study is necessary to validate the FRI.
