[Angiography in vasculitis].

The method of angiography in vasculitis has recently been changed due to the development of digital subtraction angiography (DSA). Intra-venous DSA is widely used in the diagnosis of vasculitis, although intra-arterial DSA is needed for depicting small vessel lesions. Low-osmolality contrast medium is another advancement in the angiography of vasculitis, which can make peripheral angiography painless. We discussed angiographic features in vasculitis diseases, including Takayasu arteritis, Buerger disease, moyamoya disease, and vasculo-Behçet disease. Angiography is the most important in order to diagnose vasculitis and evaluate the degree and extent of disease. Further, interventional radiology, which uses the technic of angiography for the purpose of therapy, is employed for the vascular treatment of vasculitis.
