Endovascular management of traumatic ruptures of the thoracic aorta: A retrospective multicenter analysis of 28 cases in The Netherlands

Abstract

Minimally invasive endovascular treatment of a traumatic rupture of the thoracic aorta is a new strategy in the care of multitrauma patients. We report the experience in The Netherlands with endovascular management of patients with acute traumatic ruptures of the thoracic aorta. We reviewed 28 patients with a traumatic thoracic aortic rupture treated with a thoracic aortic endograft between June 2000 and April 2004. All patients underwent treatment at one of the four participating level 1 trauma centers. Data collected included age, sex, injury severity score, type of endovascular graft, endovascular operation time, length of stay, length of stay in the intensive care unit, and mortality. Follow-up data consisted of computed tomographic angiography and plain chest radiographs at regular intervals. All patients (mean age, 40.9 years; SD, 18.5 years) experienced severe traumatic injury, and the mean injury severity score was 37.1 (SD, 7.8). All endovascular procedures were technically successful, and the median operating time for the endovascular procedure was 58 minutes (interquartile range, 47-88 minutes). The overall hospital mortality was 14.3% (n = 4), and all deaths were unrelated to the aortic rupture or stent placement. There was no intervention-related mortality during a median follow-up of 26.5 months (interquartile range, 10-34.6 months). Postoperative data showed no severe endovascular graft- or procedure-related morbidity, except for one patient with an asymptomatic collapse of the endovascular graft during regular follow-up. This was corrected by placing a second graft. This study shows that the results of immediate endovascular repair of a traumatic aortic rupture are at least equal to those of conventional open surgical repair. Especially in these multitrauma patients with traumatic ruptures of the thoracic aorta, endovascular therapy seems to be preferable to conventional open surgical repair.
