Resumen

Los estudios de imagen en el ictus isquémico agudo han avanzado en gran parte por la aparición de nuevos tratamientos eficaces en la fase aguda. La angiografía con tomografía computarizada (angio-TC), junto con los estudios de TC de perfusión, contribuyen a seleccionar pacientes para un tratamiento adecuado y precoz. El papel de la angio-TC en el ictus isquémico agudo es muy importante porque permite confirmar una oclusión vascular, valorar la circulación colateral y obtener un mapa arterial de gran utilidad para planificar el tratamiento endovascular. Con esta revisión sobre la angio-TC repasamos sus principales características técnicas y hacemos hincapié en su utilidad para hacer un diagnóstico adecuado y mejorar las estrategias terapéuticas.

Abstract

Advances in imaging studies for acute ischemic stroke are largely due to the development of new efficacious treatments carried out in the acute phase. Together with computed tomography (CT) perfusion studies, CT angiography facilitates the selection of patients who are likely to benefit from appropriate early treatment. CT angiography plays an important role in the workup for acute ischemic stroke because it makes it possible to confirm vascular occlusion, assess the collateral circulation, and obtain an arterial map that is very useful for planning endovascular treatment. In this review about CT angiography, we discuss the main technical characteristics, emphasizing the usefulness of the technique in making the right diagnosis and improving treatment strategies.
