[Atypical initial manifestation of Takayasu arteritis].

Primary clinical manifestations in patients with Takayasu arteritis are mostly unspecific signs of inflammation. First involved are the main brachiocephalic arteries and the aorta. Later the disease becomes symptomatic through organ ischemia. Often a renal hypertension appears due to an arteritic stenosis of the renal artery. Here we present a patient suffering from Takayasu arteritis. The disease first appeared with renal hypertension and an encephalopathy. The hypertension was induced by compression of the right renal artery which in turn was caused by an aortic aneurysm. The aneurysm had been resected and the aorta was reconstructed by aorto-aortal prosthetic interposition and implantation of the renal arteries. The postoperative course was uneventful.
