[Primary intraventricular hemorrhage in the adult]

Forty two instances of primary intraventricular hemorrhage (PIVH) out of overall 592 cases of intracerebral hemorrhages diagnosed by CT in 1980-1989, to evaluate the general prognosis attributable to PIVH and its factors. The mortality rate was 23.8%, and persistent residual disability was small or absent in 59.5% of patients. The prognosis was influenced by the clinical status at admission and the magnitude of ventricular bleeding. We conclude that PIVH is comparatively benign.
