Prevalencia de ictus isquémico diagnosticado por resonancia magnética en pacientes del Hospital de Especialidades José Carrasco Arteaga durante el periodo enero – diciembre de 2019

Abstract

Background: according to the World Health Organization (WHO), cerebrovascular accidents (CVA) are the second leading cause of death worldwide and the first cause of disability. Ischemic stroke is an interruption of blood supply to a vascular territory of the brain, depriving it of glucose and oxygen, causing neurological damage that can become permanent. Magnetic resonance imaging (MRI) of the brain makes it possible to assess morphological and functional aspects of the brain, obtain information on the established infarct volume, alteration of cerebral perfusion, ischemic penumbra area and affected vascular territory, which is useful for the timely diagnosis of this pathology. Objective to determine the prevalence of ischemic stroke diagnosed by magnetic resonance imaging in patients at the Hospital de Especialidades José Carrasco Arteaga during the period January - December 2019. Method: descriptive and retrospective study, a database of 144 people was used. The information was analyzed with SPSS, the results were tabulated and presented through frequency tables, percentages and measures of central tendency. Results: the study included a population of 1114 patients, with a stroke prevalence of 12.93%,occurring most frequently between 62 and 72 years of age (39.60%); the mean age was 64.21years (±14.81). Women predominated with 54.2%. Most of the cases were acute 88.2%. The most frequently identified findings were cerebral edema 52.78% and mass effect 35.42%. The most frequent location was the middle cerebral artery 68.1%. Most of the cases presented right laterality 55.6%. Conclusions: a prevalence of ischemic stroke diagnosed by MRI was obtained for the study period of 12.93%.
