Diagnostico por imagen de la disección aórtica aguda

Abstract

Introduction: Acute aortic dissection in a disease with high mortality affects the ascending aorta with or without involvement of the descending aorta. It is considered a disease of low survival due to its difficult diagnosis. In recent years, access to imaging methods that allow effective diagnosis has improved, chest radiography and transthoracic echocardiography are frequently the first tests most used in the initial assessment after being directly available, however, tests are needed with superior diagnostic accuracy, computed tomography (CT), magnetic resonance imaging (MRI) or transesophageal echocardiography. Objective: To know the imaging methods for the diagnosis of acute aortic dissection and to identify the most effective imaging method for timely diagnosis. Method: Bibliographic review of academic articles updated with randomized controlled studies of the last 5 years, obtained in Pubmed, ScienceDirect, Google academic. Conclusions: Chest radiography and transthoracic echocardiography are the most commonly used imaging methods in the initial assessment, in patients arriving at the emergency department, but after investigation we can conclude that computed tomography angiography is the most effective imaging method for diagnosis of acute aortic dissection with a sensitivity of 100% and a specificity of 98%.
