Abdominal Aortic Aneurysm Survival Is Improving Since 1987, long-term survival has increased 4.7 percent after intact aneurysm repair in Sweden
12 july 2009-- During the past 20 years, long-term survival has improved for Swedish patients undergoing intact abdominal aortic aneurysm repair and remained stable for those undergoing ruptured abdominal aortic aneurysm repair, despite increases in patient age and comorbidities, according to a study published online July 6 in Circulation.
Kevin Mani, M.D., of Uppsala University Hospital in Sweden, and colleagues studied outcomes in 8,663 patients who underwent repair for an intact abdominal aortic aneurysm and 4,171 who underwent repair for a ruptured abdominal aortic aneurysm between 1987 and 2005.
Among those who underwent repair for an intact abdominal aortic aneurysm, the researchers found that relative five-year survival, excluding 90-day mortality, was significantly higher in those treated in 2000 to 2005 than in those treated in 1987 to 1999 (93.4 versus 88.7 percent). Among patients who underwent repair for a ruptured abdominal aortic aneurysm, the rates of relative five-year survival did not significantly change between 1987 and 2005.
"Many factors, including reduction in smoking, better treatment of hypertension, and better lipid control, have been thought to have affected the overall improvement in patient survival," states the author of an accompanying editorial.
