Endoluminal stent–graft placement for acute rupture of the descending thoracic aorta

Abstract

AIMS: To investigate the results of endovascular stent-graft placement for the treatment of acute perforating lesions of the descending thoracic aorta. METHODS AND RESULTS: A total of 31 consecutive patients underwent interventional treatment for perforating lesions of the descending aorta. In 21 cases (group A), the aortic perforation was due to rupture of a descending thoracic aneurysm or dissection, whereas 10 patients (group B) were treated for traumatic transection of the descending aorta. A total of 42 endoprostheses were implanted. The implantation procedure was successful in all cases without peri-interventional complications. In one case, implantation of a second endoprosthesis became necessary due to type I endoleak. Overall, the 30-day mortality was 9.7%. As all three deaths occurred in group A, the mortality rate in this group was 14.3% versus 0% in group B. Similarly, postinterventional complications were more prevalent, with 28.6% in group A (renal failure n = 4; stroke n = 2) versus 10.0% in group B (renal failure n = 1). No paraplegia and no further deaths or ruptures occurred during follow-up (mean 17 months). CONCLUSION: Interventional stent-graft placement is an effective treatment option for the emergency repair of descending aortic perforations.
