ObjectiveThe aim of this study was to evaluate the short- and midterm results following endovascular repair of a traumatic rupture of the aortic isthmus.MethodsBetween January 2001 and January 2007, 27 patients underwent endovascular repair for acute traumatic rupture of the aortic isthmus (8 women, 19 men, mean age 40.2 +/- 16.7 years [19-78]). All patients underwent a computed tomography scan resulting in the preoperative diagnosis of aortic disruptions. Twenty-one patients were treated within the first 5 days following diagnosis. Follow-up computed tomography scans were performed at 1 week, at 3 and 6 months, and annually thereafter. The median follow-up was 40 months.ResultsAll endografts were successfully deployed (Excluder-TAG [16], Talent [10], Zenith [2]). Three patients required common iliac artery access. The morbidity rate was 14.8%: two cases of inadvertent coverage of supra-aortic trunks occurred peroperatively, a proximal type I endoleak was successfully treated by a proximal implantation of a second endograft, and one collapse of an endograft was successfully treated by open repair and explantation. No patient suffered transient or permanent paraplegia, cerebral complication, endograft migration, or secondary endoleak. The overall mortality rate was 3.7%.ConclusionsShort and midterm results following endovascular treatment for traumatic rupture of the aortic isthmus favor the proposition of endovascular repair as the first-line treatment in hemodynamically unstable patients. In hemodynamically stable patients, the preoperative morphological evaluations aim to assess aortic anatomy and thereby detect possible technical limitations (aortic diameter <20 mm, severe aortic isthmus angulation, short proximal aortic neck <20 mm, conical aorta). In the presence of any one of these technical restrictions, open surgical treatment should be discussed to avoid major per- or postoperative complications related to endovascular repair. Further studies and long-term survival studies are mandatory to determine the efficacy and durability of this technique.
