- Abstract
Purpose: To review our experience with thoracic endografting for type B aortic dissection using the TAG Endoprosthesis. Methods: A retrospective analysis was performed of data collected prospectively from March 2000 to July 2004 under an investigational device exemption protocol for the TAG thoracic endograft. In this time period, 40 patients (29 women; mean age 67 years, range 39-91) were treated with this endograft for type B aortic dissection. Results: Technical success was 95%. There was 1 (2.5%) perioperative death, and 1 (3%) endoleak was treated with an additional graft on postoperative day 2. Fifteen (38%) patients experienced postoperative complications, mainly renal or pulmonary, and 1 (3%) patient developed postoperative paraplegia that did not resolve. The 1-year survival was 85%. Follow-up computed tomography was available for 31 patients with an average 15-month follow-up. There was no significant change in size of the thoracic aorta in 22 patients; 8 aneurysmal segments were significantly reduced in size and 1 thoracic aortic aneurysm expanded. No thoracic aortic ruptures were seen in this series. Conclusions: These early results indicate type B thoracic aortic dissections can be treated with acceptable morbidity and mortality using endografts. Stent-graft repair of the thoracic aorta may decrease the incidence of thoracic aortic expansion and rupture.
