Occlusive aortic disease caused by atherosclerosis
: usually confined to the distal abdominal aorta below the renal arteries
The severity of the symptoms depends on the adequacy of collaterals
With sufficient collateral blood flow
: a complete occlusion of the abdominal aorta may occur without the development of ischemic symptoms.

Diseases of the pancreas produce back pain to the right of the spine (head of the pancreas involved) or to the left (body or tail involved)
A careful abdominal examination revealing a pulsatile mass (present in 50–75% of patients) is an important physical finding. Patients with suspected abdominal aortic aneurysm should be evaluated with abdominal ultrasound, CT, or MRI.
