Renal artery angioplasty in Takayasu disease: Difficult anatomy addressed with a novel technique

Abstract

Takayasu arteritis is a well-established medical entity involving inflammatory changes in large arteries. We describe a characteristic case of Takayasu arteritis, in a young woman with significant renal artery stenosis, presenting with hypertensive urgency. Unsuccessful guide wire passage due to fibrotic septae in lumen of the left renal artery necessitated an innovative interventional approach, using an IMA-guide catheter and a UB3 coronary guidewire to cross the lesions, followed by placement of a coronary drug eluting stent, with an aim to avoid restenosis.
