Transcatheter stent implantation for the treatment of abdominal aortic coarctation and right renal artery stenosis in takayasu's arteritis: a case with a 4-year follow up

Abstract

We describe a Takayasu arteritis patient who was admitted because of an abdominal aortic stenosis, further complicated by the presence of a stenotic right renal artery located in the area of the aortic stenosis. After treatment of the renal stenosis with a 4 × 15 mm Driver stent, a 16 × 60 self-expandable nitinol stent (OptiMed) was deployed through the stenosis of the abdominal aorta. Even though the right renal artery was initially compromised after stent deployment through the aortic stenosis, the patient was successfully treated with renal artery re-dilation by a balloon passed through open cells of the aortic stent. During follow up, the patient suffered no procedure-related complications.
