AbstractWe report two cases of intraventricular hematoma with obstructive hydrocephalus. We perform endoscopic treatment of the hydrocephalus: aspiration of the hematoma associated with a third ventriculostomy. Both patients respectively aged 59 and 74 years had an obstructive hydrocephalus due to intraventricular hemorrage. The patient neurological status worsen at day 6 for patient No. 1 and at day 4 for patient No. 2. Endoscopic ventriculoscopy was performed respectively at day 6 and at day 5. Operatively, immediate vision was poor but was progressively improved by repetitive irrigation with Ringer-lactate (RL). Obstruction of the right Monro foramen by clot was observed. Introduction of the neuroendoscope into the third ventricle was possible after suction of the hematoma. Perforation of the floor of the third ventricle was performed after identification of the mammillary bodies and the infundibulum. Neurological status recovered within 10 days after surgery and the patients were referred to a medical unit. The patients were independent at home. The one-year MRI follow-up study showed a functional acqueduc in case 1 and a non-functional acqueduc in case 2 indicating in this case that the ventriculocisternotomy was useful. Intraventricular hematoma is not a contraindication for endoscopic third ventriculostomy. If possible, waiting for 6 or 5 days to allow the structuring of the blood clot and using large irrigation RL may facilitate the endoscopic procedure. This indication for endoscopic third ventriculostomy constitutes an alternative to external ventricular drainage which is significatively associated with complication (infection and obstruction). We cannot affirm that the removal of the clots and ventriculocisternostomy versus temporary external drainage avoids secondary hydrocephalus.
