Abdominal computed tomography angiography (CTA) scan. (A) Left renal artery with 70% occlusion. The white arrow indicates the occlusion site (axial plane). (B) Ischemic changes in the left kidney (coronal plane). (C) Three-dimensional (3D) visualization using a volume rendering technique (VRT). The white arrow indicates the occlusion site in the left renal artery.

Abdominal computed tomography angiography showed 70% occlusion at the mid and distal parts of the left renal artery caused by thrombosis, which was associated with ischemic changes in the lower lobe of the left renal parenchyma (Fig. 1; Supplementary Videos 1 and 2).

Digital subtraction angiography (DSA). (A) The site of occlusion before revascularization (white arrow), (B) percutaneous transluminal angioplasty (PTA) of the left renal artery and stent insertion (white arrow). (C) Image of the left kidney after revascularization.
