Overview
Angiography is an alternative less often used imaging method for visualization of an abdominal aortic aneurysm. Angiography is helpful in determining the precise anatomy of the aorta. It can be used preoperatively in cases of a suspected suprarenal or thoracic aortic aneurysm, femoral or popliteal aneurysm, renal artery stenosis, unexplained renal insufficiency, occlusive ilio-femoral disease, or visceral ischemia.
Other Imaging Findings
Angiography
Angiographyis an alternative less often used imaging method for visualization of an abdominal aortic aneurysm. Angiography is helpful in determining anatomy of aorta precisely. It can be used preoperatively in case of suspected suprarenal or thoracic aortic aneurysm, femoral or popliteal aneurysm, renal artery stenosis, unexplained renal insufficiency, occlusive ilio-femoral disease, or visceral ischemia. However, it is not recommended for routine use in evaluation of AAA.
- Limitations of angiography include:
- Invasiveness
- High cost
- Risk of complications (eg, bleeding, perforation, embolization, nephrotoxicity associated with the dye load)
- Time involved
- Exposure to radiation
Digital Subtraction Angiography (DSA)
DSA uses less contrast material, requires less time, and is less invasive than conventional angiography. However, it is not widely available and offers no advantage over conventional CT scan.
