PURPOSE: To analyze the outcomes of endovascular treatment of thoracic aortic pathologies performed at a single center with the EndoFit thoracic stent-graft system. METHODS: From January 2002 to January 2007, 41 patients (33 men; mean age 69.3+/-9.7 years, range 48-84) were treated for thoracic aortic disease with the EndoFit stent-graft system. Patient data were retrieved from a retrospective review of hospital records. Indications for treatment were progression of aneurysm size in atherosclerotic aneurysms (n = 24, mean aneurysm diameter 7.19+/-1.48 cm), acute contained aortic rupture (n = 5), aortic dissection (n = 6), penetrating atherosclerotic ulcers (n = 4), post-traumatic pseudoaneurysm (n = 1), and post coarctation repair aneurysm (n = 1). RESULTS: The EndoFit stent-graft was successfully deployed in all 41 patients. The in-hospital and 30-day mortality rate was 7.3% (3 patients). Three (7.3%) postoperative endoleaks were recorded: a proximal type Ia and a distal Ib both resolved spontaneously at 1 and 3 months, respectively. The third patient had a persistent type Ia endoleak; conversion was necessary after 1 year. There was only 1 case of spinal ischemia, with consequent lower extremity weakness; no paraplegia was observed. During a mean 24.8-month follow-up, 2 secondary type Ia endoleaks were treated with additional stent-grafts. There were 7 (17%) deaths during follow-up. At 2 years, overall patient survival by Kaplan-Meier analysis was 70%; aneurysm-related survival was 89%. CONCLUSION: Endovascular treatment of vascular disease involving the descending thoracic aorta can be safely performed with the EndoFit thoracic stent-graft system.

Abstract

PURPOSE: To analyze the outcomes of endovascular treatment of thoracic aortic pathologies performed at a single center with the EndoFit thoracic stent-graft system. METHODS: From January 2002 to January 2007, 41 patients (33 men; mean age 69.3+/-9.7 years, range 48-84) were treated for thoracic aortic disease with the EndoFit stent-graft system. Patient data were retrieved from a retrospective review of hospital records. Indications for treatment were progression of aneurysm size in atherosclerotic aneurysms (n = 24, mean aneurysm diameter 7.19+/-1.48 cm), acute contained aortic rupture (n = 5), aortic dissection (n = 6), penetrating atherosclerotic ulcers (n = 4), post-traumatic pseudoaneurysm (n = 1), and post coarctation repair aneurysm (n = 1). RESULTS: The EndoFit stent-graft was successfully deployed in all 41 patients. The in-hospital and 30-day mortality rate was 7.3% (3 patients). Three (7.3%) postoperative endoleaks were recorded: a proximal type Ia and a distal Ib both resolved spontaneously at 1 and 3 months, respectively.
