PIVCEVIC C, Daniela et al. Characterization of vascular lesions in firearm wounds, using computed tomography (CT): Three years' experience in a Public Hospital in the southeastern area of Santiago, Chile. Rev. chil. radiol. [online]. 2013, vol.19, n.1, pp.12-19. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082013000100004.

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 of178. 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 extremities, 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. Conclusion. Although vascular trauma represents a low percentage of total trauma injuries, their seriousness, and therefore the need for early and accurate diagnosis, explains the importance of the knowledge and familiarity that radiologists should have, with that kind of injury. Extremities are the main site of vascular injury caused by penetrating wounds, affecting up to 70% in our sample. In these cases CT examinations are often only complementary because the diagnosis is made clinically; this is not the case in intrathoracic and intraabdominal vessel injuries, where images are essential for diagnosis.
