CT angiography of the aorta and renal arteries is a modern imaging technique that provides detailed visualization of the body’s main artery and the vessels supplying the kidneys. The examination is performed with intravenous contrast enhancement, allowing precise assessment of the vessel walls and detection of narrowing (stenosis), aneurysms, thrombosis, and vascular malformations.

When Is CT Angiography of the Aorta and Renal Arteries Recommended?

• When renal artery stenosis or occlusion is suspected, which may cause persistent arterial hypertension.
• For diagnosing aneurysms, aortic dissection, or congenital vascular abnormalities.
• When thromboembolism or impaired blood flow in the aorta and its branches is suspected.
• For preoperative planning before vascular surgery.
• After surgery to assess treatment effectiveness and evaluate vascular grafts or stents.

What Can This Examination Detect?

CT angiography allows physicians to evaluate the vessel lumen, determine the location and degree of narrowing, and identify calcifications or vascular malformations. The method accurately detects aneurysms, measures their size, estimates the risk of rupture, and helps assess kidney function in relation to their blood supply.
