| Popis: | Objective The introduction of aortic stent grafting in the treatment of thoracic aortic disease has pioneered unique treatment options and gained rapid clinical adoption despite a paucity of long-term outcome data. The purpose of this analysis is to examine all operations performed using thoracic aortic stent grafts at the University of Pennsylvania Health System. Methods A total of 502 operations involving thoracic aortic stent grafting were performed between April 1999 and April 2009. Patients were followed in a prospectively collected clinical perioperative registry, and long-term outcomes were determined from administrative data sources. Aortic pathologies included aortic aneurysm, acute aortic dissection (types A and B), hybrid arch repairs, reinterventions with additional stents, pseudoaneurysm, chronic type B dissection, traumatic transection, penetrating aortic ulcer, and other unique indications. Results Patients' mean age at the time of thoracic endovascular aortic repair was 70.1 ± 12.4 years, and 51% of the patients were aged more than 70 years. Some 41% of patients were female, and the majority of patients (87%) were hypertensive. Overall 30-day mortality was 10.1%. Multivariable risk factors for 30-day mortality included urgent/emergency, Stanford type A aortic dissection, perioperative spinal ischemia, type C aortic coverage, hybrid arch operation, aortic transection, chronic renal failure, and age. Neurologic complications included permanent complete or incomplete paraplegia in 17 patients (3.4%), reversible spinal cord ischemia in 26 patients (5.1%), transient stroke in 16 patients (3.2%), and permanent stroke in 23 patients (4.6%). Greater extent of aortic coverage was not associated with risk of spinal cord ischemia. Access complications, stroke, and endoleaks diminished with increased operative experience over time. Risk factors for late mortality included urgent/emergency indications, hybrid procedures, traumatic aortic transection, age, perioperative paralysis, and chronic renal failure. Patients undergoing stent grafting for type B dissection were more likely to survive than patients undergoing stent grafting for aneurysms or other indications. Conclusions Thoracic aortic stent grafting has evolved to be a viable option to complement, augment, or even replace traditional treatments for aortic disease. These data illustrate the applicability of this evolving technology in the establishment of new treatment paradigms for complex aortic pathologies. |
