In abdomenal computed tomography (CT), the left hypoplastic kidney was observed, with narrow and tortuous left renal artery, indicating congenital left renal hypoplasia or secondary contracted left kidney (Fig. 1).
Captopril-primed diethylene triamine pentaacetic acid scan (A) shows that the early uptake, perfusion, parenchymal transition time, and excretion were all delayed in the left kidney, as well as the decreased left kidney in size before embolization. 99 m Technetium-2, 3 dimercaptosuccinic acid scan (B) reveals no uptake in the left kidney, performed seven days after embolization.

On the captopril-primed diethylene triamine pentaacetic acid scan, the early uptake, perfusion, parenchymal transition time, and excretion were all delayed in the left kidney, as well as the decreased left kidney in size (Fig. 2). After the procedure, there was no uptake in the left kidney on dimercaptosuccinic acid (DMSA) scan, showing complete occlusion of the left renal artery (Fig. 2).
Renovascular angiogram. Pre-embolization (A) and post-embolization (B) showing left renal artery stenosis, tortuous change, and total left renal arteries suppression.

At the end of the procedure, another arteriogram confirmed the complete suppression of arterial flow to the left kidney (Fig. 3).
