Review of a 10-year single center experience in treatment of thoracoabdominal aortic trauma

Objective To review the case data and treatment methods in a single center so as to search for rational treatments for thoracoabdominal aortic trauma. Methods This retrospective analysis was performed for 34 cases (28 males and 6 females) sustaining thoracoabdominal aortic trauma treated from October 2002 to February 2013. The mean age was 41 years (range, 11-60 years). Causes of injury included traffic crashes in 14 cases, high falls in 7, stab wound in 3, abdominal crash injury in 3, aorticoesophageal fistula caused by a fish bone in 3, interventional therapy-induced aortic dissection in 2, abdominal aortic injury caused by the dropped ventricular septal defect occluder in 1, and accidental aortic injury in spinal operation in 1. There were 23 cases of thoracic aortic trauma (6 sharp and 17 blunt) and 11 cases of abdominal aortic trauma (4 sharp and 7 blunt). Preoperative imaging findings, treatment methods and follow-up data were studied. Results Personal treatment was produced based on the mechanism of injury and imaging findings. Of sharp thoracic aortic trauma, 2 cases were treated non-operatively but both died, and four cases had endovascular repair (one progressed, two cured, and one died). All the four cases of sharp abdominal aortic trauma had open surgery (three cured and one severely complicated). Of thoracic aortic trauma, four cases were treated non-operatively (three cured and one died), twelve cases had endovascular repair (11 cured and one died), and one case had open surgery and cured. Six cases of blunt abdominal aortic trauma were treated non-operatively and one had open surgery. Conclusions Treatment of aortic trauma should be based on injury condition, injury site, and occurrence of aortic rupture or impending of aortic rupture. Endovascular repair has a high success rate and good clinical outcome in treatment of thoracoabdominal aortic trauma. Key words: Aorta; Wounds and injures; Endovascular repair
