Escala de Fisher como factor predictor de hidrocefalia en hemorragia subaracnoidea espontanea

Abstract

Objective: Determine the amount of blood and its location is the subarachnoid space, measurable with the Fisher scale in the first 24 hours after the hemorrhagic stroke is a predictor for the development of hydrocephalus in patients with subarachnoid hemorrhage (SAH) spontaneous, seen at the academic Hospital, San Rafael Clinic (HUCSR) followed for 12 months. Methods. 251 patients were included in a retrospective cohort. The association between Fisher scale and development of hydrocephalus in patients with spontaneous SAH was analyzed through bivariate and multivariate analysis. Results. The average age of patients was 55. 5 ± 15 years, with predominance in females 65. 7%. Hydrocephalus prevalence was 27. 1% in the cohort and the etiology of HSA was mostly due to rupture of cerebral artery aneurysms, 78. 5%. Survival at 12 months was 65. 7%. Both the level 4 on the scale of Fisher and Hunt-Hess III are associated with the development of hydrocephalus: ORA; 2. 93, 95% CI 1. 51-5. 65, P < 0. 001, 2. 83 ORA 95% CI 1. 31-6. 17 P = 0. 008 respectively. Conclusion. Intraventricular presence or intracerebral bleeding (Fisher 4) in the first 24 hours, associated with neurological impairment admission Hunt-Hess III are associated with the development of hydrocephalus in 251 patients diagnosed with HSA evaluated spontaneous findings consistent with the reported in the world literature.
