Aorto-renal Bifurcation Stenting in a Juvenile Non-specific Aorto-Arteritis: case report

Abstract

Takayasu Arteritis (TA) is a granulomatous inflammation of unknown aetiology affecting the aorta and its major branches with usual affliction among patients younger than 50 years and rarely among children. We present a 7-years old boy referred for evaluation of hypertension. He had a significant blood pressure difference between right arm, left arm and lower limbs. Computed tomography imaging of thorax and abdomen showed stenosis of left subclavian artery, left renal artery and juxtarenal aorta which was subsequently confirmed on aortogram. He underwent percutaneous endovascular therapy with aorto-renal bifurcation stenting with reduction of blood pressure and gradient. Renal angioplasty with stenting remains a challenging procedure in patients with tight ostial lesion, and juxtarenal aortic involvement in lieu of precise stent placement and avoiding side branch occlusion.
