External ventricular drainage for acute obstructive hydrocephalus developing following spontaneous intracerebral...

There is no consensus in the literature on the effects of the development of hydrocephalus on survival and disability after intracerebral haemorrhage (ICH) and the benefits of external ventricular drainage (EVD). In this open, prospective study, we investigated the clinical courses, radiological findings and outcome scores of 47 consecutive patients who were admitted to our clinic with spontaneous ICH. Hydrocephalus developed in 6 (12.8%) of the 47 patients, and EVD was applied in these 6 cases. In one of the 6 patients, the lesion was additionally excised due to the large cerebellar haematoma. Intraventricular haemorrhage was more common in patients developing hydrocephalus (83.3% vs. 29.3% in patients without hydrocephalus; p<0.05) and the lesions of all the patients were in the proximity of the ventricular system. Hospital mortality and functional outcome were not significantly different between patients with and without hydrocephalus. Our results shown that acute obstructive hydrocephalus should be anticipated if haematoma is near the ventricle or if it is opening to the ventricle. EVD is a life-saving and effective procedure that should be performed in patients who develop hydrocephalus following spontaneous intracerebral haemorrhage.
