Takayasu's arteritis

The monitoring interval should vary inversely with the level of disease activity, being shorter for those with more active disease. However, as the disease may become active without new constitutional symptoms, regular follow-up is needed. In addition to history and physical examination, erythrocyte sedimentation rate, C-reactive protein, and full blood count should be checked at each visit. Vascular imaging studies such as computed tomography or magnetic resonance angiography should be performed every 3 to 12 months during the active phase of treatment and annually thereafter.
