Retrospective evaluation of 22 patients with Takayasu's arteritis.

Takayasu's arteritis (TA) is a rare, idiopathic, inflammatory, granulomatous vasculitis that affects the aorta and its primary branches. Clinical features and the pattern of arterial involvement show differences in different regions of the world according to ethnic influences. Our aim in this retrospective study was to evaluate the demographic, clinic, laboratory, and angiographic findings of 22 patients with TA followed by our clinic and also compare our results with series from the literature. The hospital files of the 22 patients followed by our clinic between 1998 and 2009 were retrospectively evaluated. We also compared our results with the series from the literature that we were able to reach by US National Library of Medicine, National Institute of Health. Gender distribution, age at diagnosis, and type of aortic involvement were similar with the study from Turkey. Different clinical manifestations of Takayasu's arteritis have been described in different ethnic groups. We also want to underline the coincidence of TA and other rheumatic diseases such as sarcoidosis, SLE, RA, and psoriatic arthritis, different from other published series.
