Objective : A retrospective study is performed on 28 patients with primary intraventricular hemorrhage(PIVH) to examine the outcome and prognostic factors associated with this disorder.
Methods : Clinical data collected between 1998 and 2002 was used in the present study. The outcomes of these patients were compared by age, etiology, initial Glasgow Coma Score(GCS), Graeb´s score, ventriculocranial ratio(VCR), hemorrhagic dilation of the third ventricle, and hemorrhagic dilation of the fourth ventricle. The Glasgow Outcome Scale(GOS) at discharge was used for the comparison of outcomes.
Results : The mean age of these patients was 48.417.4 years. The underlying causes of PIVH were hypertension (53.6%), moyamoya disease J 7.9%), arteriovenous malformation (10.7%), cerebral aneurysm (7.1%), and unknown (10.7%). The age and etiology were not correlated with outcome. Patients with a GCS of 13-15 showed a good outcome in 90.5%(p<0.05). Those with a higher VCR (20.23) showed a poor outcome in 64.3%(p<0.05). Patients with a Graeb´s score of 9-12 showed a poor outcome in 87.5%(p<0.05). Those with hemorrhagic dilatation of the third ventricle showed a poor outcome in 80.0%, and those with hemorrhagic dilatation of the fourth ventricle showed a poor outcome in 85.7% (p<0.05). The overall mortality rate was 17.9%.
Conclusion : Low initial GCS, high Graeb´s score, high VCR, and hemorrhagic dilatation of the third ventricle or the fourth ventricle are correlated with poor outcome in PIVH.
