title: [Clinical and angiographic manifestations inpatients without previous diagnosis of Takayasu´s arteritis].
abstract: BACKGROUND
  Takayasu's arteritis is a systemic vasculitis that affects the aorta and its main branches mainly seen in young women and it is characterized by decrease or absence of pulses. The arteriography is necessary to corroborate the diagnosis. The aim of this article is to analyze the clinical manifestations and radiological findings in patients with no previous diagnosis of TA.
  
  
  METHODS
  The patients were sent to the Department of Radiodiagnosis and Imaging for the performance of an angiography for cerebrovascular disease (CVD) in young patients, renovascular hypertension (RVH) and arterial insufficiency (IA) of limbs. Clinical manifestations were used to investigate the diagnosis of AT according to the criteria of the American College of Rheumatology 1990. A digital subtraction angiography (DSA) was performed and the type of AT was evaluated according to Numano classification.
  
  
  RESULTS
  There were 10 women with an average age of 32.4±10 years. The reasons for the study of these patients were stroke in young patients 4, RVH 3 and AI of upper extremities 3 patients. The main types of TA were I: 50%, V: 40%, IV 10%. The main arterial involvement were the supraaortic trunk and both carotids 80%, right subclavian 80%, left subclavian 70%, left vertebral 40%, right vertebral 30%, thoracic aortic 40%, abdominal aortic 40%, right renal 40% and left renal 10%.
  
  
  CONCLUSIONS
  The most frequent clinical manifestations were stroke in young patients, RVH and AI. The AT type I was the most common, followed by V and IV respectively, which explains the clinical manifestations.
