Learning objectives: To illustrate the MDCT angiography findings in patients with renal vascular lesions. To underline the role of 3D CTA for preoperative screening and assessment of surgical treatment.

Background: Renal vascular abnormalities include renal artery aneurysms (RAA) and renal arteriovenous malformations (AVM).   Renal arteriovenous shunts are rare pathologic communications between the renal arteries and veins without interconnecting capillar­ies. Their prevalence is approximately 0.04% of th[...]

Findings and procedure details: Ar­terial phase CT angiographic images are typically obtained 20–30 seconds after the onset of periph­eral intravenous injection at a rate of 3–4 mL/sec. The volume and mixture of contrast materials can vary, but typically 120–150 mL of iodinated contrast material is used. A multiphasic scan, at lea[...]

Conclusion: MDCT angiography with 3D imaging provides a unique opportunity for non-invasive investigation in virtually all conditions that affect the renal arteries. It’s also used for deeper study of the vascular anatomy of the kidneys and its variations especially when the surgical planning is crucial to the[...]
