a-d Coronal CTA (a) and 3D VR imaging (b) at 6 month FU, showing a patent sidebranch (arrow), which appears smaller in comparison to baseline CT and DSA (see above Figs. 1 and 2), directed to the upper pole of the kidney. c and d show the same finding at the 12-month FU: the sidebranch ostium is occluded as well as the aneurysm. However, the distal branching vessel is still patent (curved arrow), probably thanks to collateral circulation
