    Abstract:
    The usefulness and limitation of digital subtraction angiography (DSA) in Takayasu arteritis were investigated in 32 patients. Intravenous DSA was particularly useful in the follow-up of patients with an established diagnosis of Takayasu arteritis. Pulmonary arterial involvement could also be demonstrated with intravenous DSA as obstructive arterial changes and lack of accumulation of contrast medium in the pulmonary parenchyma. Detailed information concerning the site and extent of vascular involvement and development of collateral vessels were obtained with intraarterial DSA. Thickening of the thoracic aortic wall, however, could not be recognized with either intravenous or intraarterial DSA. Conventional angiography of the descending thoracic aortal is still required as an initial examination, particularly when there is no aortic arch involvement. However, there is no doubt that DSA has the potential to become the diagnostic procedure of choice in Takayasu arteritis.
