Takayasu Arteritis as a Secondary Cause of Arterial Hypertension

Abstract Takayasu arteritis (TA) is a rare type of vasculitis that affects mainly the aorta and its major branches. It is highly similar to giant cell arteritis (GCA), and differentiation between them may not be achieved even by histological examination. Arterial hypertension is typical of TA and is caused by stenosis of the renal arteries. Here we report the case of a 59-year-old woman, with a history of dyslipidemia and anemia, seen in the Internal Medicine department for resistant hypertension. Evaluation of secondary causes led to stenosis of the renal arteries. Assessment of target organ involvement was performed by computed tomography angiograph which revealed ectasia of the aortic arch and ascending aorta, tortuous course of the brachiocephalic trunk and the proximal portion of the right common carotid artery; positron-emission tomography which showed diffuse increased uptake in the ascending aorta, compatible with large vessels vasculitis. The patient was submitted to aortic valve replacement with a biological prosthesis combined with myocardial revascularization (Bentall-De Bono procedure). Aortic biopsy specimens showed anatomical and pathological features of GCA and TA. Due to persistently uncontrolled hypertension, prednisone 60 mg was initiated,with significant improvement in patient’s condition.
