Hallevi et al developed an intraventricular hemorrhage score (IVHS) for estimating the volume of intraventricular blood for a stroke patient. The presence of intraventricular hemorrhage may indicate a worse prognosis. The authors are from the University of Texas at Houston and Tulane University.
Parameters:
(1) blood in right ventricle
(2) blood in left ventricle
(3) blood in the III ventricle
(4) blood in the IV ventricle
(5) points for hydrocephalus
