A Novel Score to Predict Risk of Symptomatic Intracerebral Hemorrhage

The Henan-PRIHS was developed from 95 patients who underwent IA-CEFDCT and MT for acute anterior stroke. Patients were classified as having one of three grades according to the presence of contrast filling within the occluded vascular territory. Grade 0 was normal or less contrast filling in affected hemisphere, grade 1 and 2 were small and medium-large area without contrast filling, respectively. The Youden index was used to determine the optimum no contrast filling area cutoff for defining grade 1 and 2. The score was subsequently validated in a different population of 208 patients and compared with three established scores.
