Overview

Angiography is an alternative less often used imaging method for visualizing an Thoracic aortic aneurysm (TAA). 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, and visceral ischemia.

Other Imaging Findings

Angiography

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 a conventional CT scan.
