Abstract

The present study was carried out to determine the risk factors associated with peri-operative mortality and long-term survival in patients undergoing abdominal aortic reconstructive surgery (ARS). A retrospective review was performed of the case notes of all patients having ARS at a university teaching hospital during a 5.5-year period, and their details entered onto a pro forma. A total of 252 patients underwent ARS between July 1989 and December 1994. The peri-operative mortality was 7.5%. The most frequent adverse events were cardiac events, accounting for 8 (42%) of the peri-operative deaths. The risk of a peri-operative cerebrovascular accident was low (n = 3, 1.2%) as was the risk of peri-operative renal failure requiring dialysis (n = 3, 1.2%). Factors independently linked to increased peri-operative mortality included moderate-to-severe hypertension (P = 0.05, odds ratio = 3.54), those with renal impairment (P = 0.05, odds ratio = 2.69), and blood transfusion requirements (P < 0.001, odds ratio = 1.26). Long-term survival was independently shortened by occlusive disease (P = 0.004, hazard ratio = 2.78) and ischaemic heart disease (P < 0.001, hazard ratio = 3.58). The risks of ARS were significantly increased in patient...Continue Reading

Aortic Aneurysm

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.
