Bail-Out Percutaneous Intervention for Chronic Total Occlusion of the Left Renal Artery Secondary to Takayasu’s Arteritis in a Pediatric Patient Using Drug-Eluting Stent

Abstract

Renal-artery stenosis/occlusion is the cause of ischemic nephropathy, which is associated with hypertension due to renovascular system involvement. Acute renal failure in patients with bilateral renal artery stenosis can occur for a variety of reasons, including administration of an angiotensin-converting enzyme inhibitor or spontaneous progression of renal-artery stenosis leading to bilateral total occlusion or high-grade stenosis. Rapid diagnosis and prompt treatment are the basis of kidney survival. The root cause of renal-artery occlusion must be elucidated in younger age patients after revascularization, such as Takayasu’s arteritis (TA) or fibromuscular dysplasia. We discuss the case of a preadolescent girl who had bilateral complete renal artery occlusion due to TA and acute kidney injury, needing renal replacement therapy. She had a bailout percutaneous renal intervention to the left renal artery, which resulted in remarkable clinical improvement.
