Caracterización de las lesiones vasculares por tomografía computada (TC) en heridas de arma de fuego: Experiencia de tres años en Hospital Público del sector suroriente de Santiago de Chile

Abstract

Abstract: Objectives. To determine the epidemiological and CT characteristics of vascular lesions in patients who have suffered gunshot wounds, in the emergency department of a public hospital in Santiago, Chile, over a period of three years. Material and Methods. Retrospective review of 211 CT performed on patients admitted to the emergency department with gunshot wounds, between 31/05/2009 and 31/05/2012. Patients with a CT within the first 48 hours after the event occurred were included, excluding patients who for their clinical condition, underwent surgery prior to the CT, obtaining a final number of 178. Distribution was analyzed by sex, age, type of vascular injury, topographic segment affected, projectile type and outcome of patients. Results. 96.8% (n° = 31) of those affected were men, 71.8% under 36 years. The most affected segment were to the lower extremi -ties, with 55.8%. The most frequent type of injury was pseudoaneurysm and active hemorrhage, with 20.5% in each case. The type of projectile most frequently found were bullets (65%) and the majority, without projectile exit. In our group there was 1 death.
