COMPARATIVE STUDY
JOURNAL ARTICLE
Emergency repair of traumatic aortic rupture: endovascular versus conventional open repair.
Journal of Thoracic and Cardiovascular Surgery 2007 October
OBJECTIVE: Our objective was to compare early results of endovascular stenting for traumatic aortic rupture with conventional open repair.
METHODS: We conducted a retrospective review of consecutive cases of traumatic aortic rupture in a single institution from July 2000 to July 2006.
RESULTS: Fifteen cases were identified. The mean injury severity score was 43 +/- 10. Fourteen patients had the procedure within 24 hours of admission to the hospital. Seven patients underwent endovascular stenting and 8 underwent open repair. For endovascular stenting, there were no failed procedures, no periprocedural complications, and no periprocedural deaths. In 6 patients, there was no evidence of endoleak, stent migration, or late pseudoaneurysm formation. One patient required a second stent 2 years later to treat a stenosis in the original stent. For open repair, cardiopulmonary bypass was used in 7 of the 8 patients. Lower limb paraplegia developed postoperatively in 1 patient and another patient died of head injuries. There was a significant reduction in the mean duration of the procedure (2.2 +/- 0.90 vs 5 +/- 3.2 hours; P = 0.04), the mean intraoperative blood loss (311 +/- 20 vs 953 +/- 20 mL; P = .02), the mean number of units of blood and blood products used (0.43 +/- 1.1 vs 3 +/- 3 units; P = .026), and the mean dose of heparin required (5000 +/- 1700 vs 24,000 +/- 7500 IU; P = .001) in the endovascular stenting group. There was no difference in duration of ventilation, intensive treatment unit, or hospital stay.
CONCLUSIONS: Endovascular stenting is technically feasible and applicable to a range of cardiac patients. It takes less time than open repair, requires less heparin and blood products, and therefore simplifies management of other injuries. In hemodynamically stable patients, endovascular stenting is the treatment of choice for traumatic aortic rupture.
