| dc.description.abstract | La hemorragia subaracnoidea no traumática (HSA) debida a la ruptura de un aneurisma cerebral es un evento catastrófico asociado con altas tasas de morbilidad y mortalidad. Es un problema clínico mayor con una incidencia en Estados Unidos de 1 por 10.000 habitantes (17). Aproximadamente el 12% de los pacientes mueren antes de recibir atención médica, el 40% de los hospitalizados mueren durante el mes posterior al episodio y más de la tercera parte de los que sobreviven padecerán un déficit neurológico mayor. (17) A la Fundación Oftalmológica de Santander / Clínica Carlos Ardila Lülle (FOSCAL), de Enero de 2003 a Abril de 2005 consultaron al servicio de urgencias 161.354 pacientes, de los cuales 1223 (0,75%) correspondieron a cefaleas, siendo 58 (4.7%) de estas diagnosticadas como hemorragias subaracnoideas no traumáticas, para una incidencia en la población consultante a la FOSCAL de 3,6 HSA no traumáticas por cada 10.000 consultantes de los servicios de urgencias.

It is a major clinical problem with an incidence in United States of 1 per 10,000 inhabitants (17). About 12% of patients die before receiving care medical, 40% of those hospitalized die during the month after the episode and more than a third of those who survive will suffer from a neurological deficit elderly. (17) To the Ophthalmological Foundation of Santander / Carlos Ardila Lülle Clinic (FOSCAL), from January 2003 to April 2005 they consulted the emergency service 161,354 patients, of which 1223 (0.75%) corresponded to headaches, being 58 (4.7%) of these diagnosed as subarachnoid hemorrhages traumatic, for an incidence in the population consulting the FOSCAL of 3.6 Non-traumatic HSA for every 10,000 emergency room consultants (Source: FOSCAL Statistics Department). | spa |
