Correlation of Scoring Systems with the Requirement of an External Ventricular Drain in Intraventricular Hemorrhage

BACKGROUND: External ventricular drainage (EVD) is intraventricular hemorrhage (IVH). The correlation of hydrocephalus related to IVH is currently unknown. METHODS: We identified 213 hypertensive patients with IVH and divided them into 2 groups according to treatment method: 187 patients receiving blood pressure control alone and 26 patients undergoing EVD. The following patients were excluded: pediatric patients, patients undergoing intracranial hematoma removal, patients with fetal status, and patients without sufficient clinical data. We compared the Glasgow Coma Scale score, Graeb score, LeRoux score, Evans index, and bicaudate index values between the 2 groups and determined the prognostication accuracy of each scoring system. RESULTS: There were significant differences in all 4 scoring systems between the 2 groups (P < 0.001). The cutoff values (sensitivity and specificity) of each scoring (80.8%, 76.5%); Evans index, 0.245 (80.8%, 67.9%); and bicaudate index, 0.186 (76.9%, 76.5%). The value of the area nder the curve of each scoring system (95% confidence and bicaudate index, 0.778 (0.673-0.883). CONCLUSIONS: The LeRoux score is better for identi-fying patients with IVH who are more likely to have EVD.
