title: [A prospective study of subarachnoid hemorrhage in Navarra].
abstract: The authors evaluate subarachnoid hemorrhage (SAH) in the autonomous community of Navarra during 3 years. Ninety-five patients were evaluated (mean age (MA) 51.47 years). They were divided in groups depending on angiographic findings. Thirty-four had an intracranial aneurysm (MA 5%.23 years) with a female preponderance (66.7% vs 33.3%). Eight patients had an arteriovenous malformation (AVM) (MA 33.7 years); in 35 patients the angiographic study was negative (MA 44 years) and in 18 angiography was not carried out (MA 66.66 years). Computed tomography was positive in 40% of patients and there was a correlation between the amount of blood in the cisterns and poor outcome of patients after 6 months. In the discussion, the authors emphasize the high incidence of SAH without angiographic findings.
