A Novel Approach to Renovascular Hypertension in Takayasu Arteritis

Abstract Takayasu arteritis (TA) is an immune arteritis causing inflammation of the aorta, its major branches, and pulmonary arteries. It is predominantly a disease of young women, with onset typically between the ages of 20 and 30 years. Renal artery stenosis (RAS) is a significant cause of hypertension in patients with TA. An autologous conduit is preferred for renal revascularization in pediatric and young patients. We report a 26-year-old male patient, a case of TA with renovascular hypertension on four antihypertensive drugs presented to us with flash pulmonary edema. Computed tomography angiogram revealed bilateral RAS. The echocardiogram showed global hypokinesia with moderate left ventricular dysfunction. Surgical revascularization was done using a bifurcated common iliac artery (CIA) as a conduit with inflow from the aortic graft to both renal arteries. The purpose of this article was to highlight that bifurcated CIA can be used as an alternative conduit to revascularize both renal arteries.
