Endovascular treatment of blunt thoracic aortic injuries

Abstract

A new era has begun in the last two decades with the advent of endovascular methods in the therapy of blunt thoracic aorta injuries. Our experiences with the endovascular interventions of blunt aortic trauma in the Cardiovascular Center of Semmelweis University are summarised here. We included those patients who underwent endovascular intervention due to blunt aortic trauma in a university hospital between 1998 and 2014. The statistical analysis was performed with the use of Excel. 41 patients were selected from our database. There were 34 males, the average age was 47 years (±17 years). Among the 41 patients 15 underwent an acute procedure (12 ruptures) and 26 patients received delayed treatment (in 4 cases due to growing of the pseudoaneurysm). There was only one early postoperative death. Late mortality was 22.5% and 7.5% was related to the aortic injury. Our late mortality and complication rates were similar to other studies, which reinforces international experiences. In the cases when delayed treatment is feasible, the patient can be stabilized and the CTA images can be analyzed for precise stentgraft planning. The treatment of blunt thoracic aorta injured patients should take place in specialized centers capable of such endovascular interventions.
