Endovascular stent placement for management of total renal artery occlusion in a child.

Total renal artery occlusion is a rare complication of percutaneous transluminal angioplasty. An 8-year-old boy was referred due to left renal artery stenosis after unsuccessful balloon angioplasty. Total left renal artery occlusion was diagnosed by angiography. The combination of balloon angioplasty and stent placement allowed reestablishment of perfusion and salvage of a severely threatened kidney. His blood pressure improved after the procedure and returned to normal 3 months later. The patient has remained free of symptoms for 12 months without medication.
