Abdominal aortic aneurysm repair in octogenarians versus younger patients in a tertiary referral center
Operative survival is as high as 96% for elective abdominal aortic aneursym (AAA) repair but as low as 10% for emergency repair. Our primary aim was to compare elective AAA repair in octogenarians with nonoperative management. Our secondary aim was to compare octogenarians with their younger counterparts. From 1998 to 2003, 180 patients with AAA were treated operatively or nonoperatively. Factors determining treatment included American Society of Anesthesiologists grade >or= 4, inoperable malignancy, New York Heart Association class III, forced expiratory volume in 1 second < 35%, creatinine > 6.0 mg/dL, and patient and family choice. A parallel-group observational study was performed to assess age and treatment effects on outcome. Seventy (39%) patients were repaired electively, 68 (38%) were managed nonoperatively, and 42 (23%) underwent emergency repair. Fifty-nine (33%) were octogenarians. The octogenarian 5-year survival rate was 20% following emergency repair, 42% if treated nonoperatively, and 83% following elective repair. Younger cohort rates were 55% (emergency), 44% (nonoperative), and 76% (elective). The octogenarian mean expansion rate was 0.26 cm/yr in those treated nonoperatively and 1.04 cm/yr in confirmed ruptu...Continue Reading

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
