Response to external ventricular drainage in spontaneous intracerebral hemorrhage with hydrocephalus.

We retrospectively reviewed consecutive intensive care unit patients with spontaneous supratentorial intracerebral hemorrhage (i.c.h.) and hydrocephalus who were treated with ventriculostomy to determine intracranial pressure (i.c.p.), Glasgow Coma Scale (GCS) score, and ventricular volume before and after ventriculostomy. Of 22 patients studied, ICP was controlled at < 20 mm Hg in 20. Only one patient had an improvement in both hydrocephalus and GCS. The three patients who survived to 3 months (modified Rankin scores of 0, 0, and 1) were characterized by very small ICH volumes and stable or improving hydrocephalus and GCS.
