Renovascular hypertension is caused by narrowing of the arteries supplying the kidneys. There are several methods to treat renal artery stenosis, such as medications, percutaneous transluminal renal angioplasty, and atherosclerosis. A boy presented to our hospital with severe hypertension. Computed tomography angiogram revealed severe narrowing of the left renal artery and hypoplastic left kidney. Total renal artery embolizaton was performed to make a complete occlusion of the left renal artery. Follow-up renin and aldosterone levels were gradually decreased. The main advantage of renal artery embolization is that it is minimally invasive compared with extensive surgical procedures. Therefore, renal artery embolization should be considered as an alternative to surgical nephrectomy in pediatric patients with renovascular hypertension.

  • Fig. 1 Computed tomography, abdomen. Horizontal view (A) and coronal view (B) showing left renal arteries stenosis and hypoplastic left kidney (white arrows).

  • Fig. 2 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.

  • Fig. 3 Renovascular angiogram. Pre-embolization (A) and post-embolization (B) showing left renal artery stenosis, tortuous change, and total left renal arteries suppression.
