Endograft therapy for diseases of the descending thoracic aorta: results in 43 high-risk patients.
2002
Purpose:To report an initial experience with endovascular stent-graft implantation for diseases of the descending thoracic aorta in high-risk patients.Methods:Forty-three patients (28 men; mean age 67 years, range 17–82) with 16 descending thoracic aortic dissections, 14 aneurysms, 7 contained ruptures, 3 mycotic aneurysms, 2 posttraumatic pseudoaneurysms, and an aneurysm of an anomalous right subclavian artery were treated between June 1999 and July 2001. Twenty-three (53%) patients were treated emergently.Results:There were no conversions to open repair, but 3 (7%) patients died during the first 30 days (pneumonia, multiorgan failure, and acute bowel ischemia). Thirteen (30%) patients suffered 18 major complications (8 strokes, paraplegia in 3, respiratory insufficiency in 6, and 1 renal failure). Of 7 (16%) endoleaks detected in the early postoperative period, 3 required additional stents, while the other 4 were treated conservatively. Follow-up, which averaged 19 ± 6 months (median: 13; range 0–34), w...
