Aresorbtive hydrocephalus after aneurysmal subarachnoid hemorrhage

Background / objective The origin, terms of hydrocephalus development, methods of treatment and results are reviewed. Methods Sixty-six consecutive patients, operated on for ruptured intracranial aneurysm (IAn) and surviving within 6 months were included into the study. Seven ventriculoperitoneostomies due to aresorbtive hydrocephalus after 66 aneurysmal subarachnoid hemorrhage (AnSAH) cases were performed in the Department of Neurosurgery, Vilnius University Emergency Hospital (2000–2002). The follow up period after AnSAH was 1 year. All cases of aresorbtive hydrocephalus were determined within 2 months after AnSAH. Results Surgical treatment of aresorbtive hydrocephalus was effective in 6 patients out of 7 (85.7%). Conclusions Our results suggest a significant role of predictive signs on initial computer tomography, location of IAn and patient’s age in the development of aresorbtive hydrocephalus
