Why the study?
What are the risk factors and demographic associations for increased abdominal aortic diameter in patients with lower limb atherosclerosis?
What are the risk factors and demographic associations for increased abdominal aortic diameter in patients with lower limb atherosclerosis?
In patients with lower limb atherosclerosis, abdominal aortic diameter increases with age and is associated with smoking, hyperlipidemia, hypertension, and iliac stenosis.
May guide age- and sex-specific AAA risk assessment in atherosclerotic patients; hypothesis-generating and requires prospective validation.
The diameter of the infrarenal abdominal aorta was measured by ultrasonography B- mode scan in 1,413 surgically intact patients with atherosclerosis of the lower limbs. There was a similar increase in abdominal aortic diameter with age in both sexes. Pathologic diameter in men patients was recorded mainly after sixty years of age: in women patients it was observed after the age of seventy. The major risk factors for aortic aneurysm in atherosclerosis obliterans of the lower limbs are smoking, hyperlipidemia with elevated levels of cholesterol, and all three factors combined in association with hypertension. Abdominal aortic diameter was only significantly affected by iliac stenosis.
