IVDSA appears to be a reliable method and should therefore be considered as a first step examination when Takayasu's disease is suspected. The simplicity and safety of the method provide a rationale for the use of this technique in Takayasu's disease. Therapeutic decisions can usually be obtained without further radiological investigation, and conventional arteriography has to be performed only when data obtained with IVDSA are insufficient. In these rare cases, conventional arteriography aims at the investigation of a particular area. The site of arterial puncture can be precisely guided by IVDSA.
