[Iliac aneurysm compared with abdominal aorta aneurysm].
The aim of the study was to compare the epidemiology, risk factors and manifestations of iliac and abdominal aortic aneurysm (AAA). Two studies were used: 1. Five thousand four hundred and seventy 65-73 year old men invited to screening for AAA. 2. Review of all 350 patients operated for central aneurysms in the county of Viborg in Denmark 1989-1997. Four thousand one hundred and seventy-six attended screening. One hundred and seventy (4.0%) had an AAA. Twenty-one (0.56%) required operation, while the prevalence of operation-requiring iliac aneurysm (IA) was 0.17%. The operative incidence of IA was 18.4 per mill. per year, and 92.4 per mill. per year were operated for AAA. Patients with IA had lower cholesterol-levels, and urological symptoms were present in 42% of cases with isolated IA, and 25% of combined aneurysms compared to 8% of isolated AAA (p < 0.05). Fifty-eight percent of the isolated IAs were ruptured, while only 27% of AAAs were ruptured (p < 0.05). The per- and postoperative mortality was 57% in ruptured isolated IA, 47% in ruptured combined aneurysms, and 31% in ruptured isolated AAA (p < 0.05). IA seems to be more under-diagnosed than AAA, and are often diagnosed because of clinical manifestations, especially urological or rupture. They seem more lethal in ruptured cases.
