ABSTRACT

Purpose. Evaluate cerebral perfusion early using tomography, in patients with ischemic EVC, detecting the penumbra to reduce mortality and sequelae.
Material and methods. An observational, transversal, retrospective and descriptive study. Fifty patients with diagnosis of ischemic EVC were included by probabilistic sampling. A Siemens® Sensation 16 (16 sections) multisection helical tomograph was used.
Results. Of the 50 patients: the penumbra was larger than that of damaged tissue in 48%, in 32% the opposite was true. In 20% of the patients the areas were equal, mostly involving the frontal and parietal lobes (28 and 24%, respectively). The condition occurred more in male patients (56%) than in female patients (44%). The highest frequency peak was seen in the 53 to 79 year age group (70% of patients). On the Glasgow scale 28 patients (56%) were in the 9 to 13 range and 56% presented systemic arterial hypertension, diabetes mellitus, and obesity.
Conclusion. Technological advances in neuroimaging (cerebral perfusion by tomography) provide opportune diagnosis and treatment, reducing mortality and sequelae.
