Successful Percutaneous Renal Artery Angioplasty and Stenting for Acute Oliguric Renal Failure in a Solitary Functioning Kidney Caused by Takayasu's Arteritis

ABSTRACT

Takayasu's arteritis (TA) is a nonspecific, chronic and stenotic panarteritis which usually involves the aorta and its major branches. Corticosteroid and immunosuppressants are recommended to manage the acute inflammatory phase, but their long term benefits are uncertain. Blood pressure (BP) control during the chronic phase of TA is essential to preserve renal function, which is associated with the patient's long-term prognosis and survival. Revascularization in organ damaging arterial stenosis with percutaneous angioplasty (PTA)/stenting or bypass surgery have been accepted as established treatment options in chronic complicated phase of TA. We present a case of a 31-year-old female patient with a two-day history of sudden onset oliguria and generalized edema whose acute oliguric renal failure was successfully reversed following PTA and stenting in a solitary functioning kidney with critical renal artery stenosis (RAS) caused by TA.
