Takayasu Arteriti Tanı ve Takipte Görüntüleme

Abstract

This study is aimed to investigate the imaging features of TA patients, who are followed by Hacettepe University Faculty of Medicine Rheumatology Department, at the disease onset and follow up. 97 TA (F/M:14/1) patients registered in the Hacettepe University Vasculitis Center database were enrolled in this study. Firstly, the demographic data, type of imaging method and therapeutics at the disease onset were evaluated. In the second part, 53 patients with a follow-up imaging at 12± 3 months were selected and disease activity status at imaging, laboratory values and the type of immunsuppresive drugs used were noted. The mean age of TA patients was 43± 14,4 years and mean disease duration was 8,6 ± 5,2 years. The delay of diagnosis was 33,3±47,7 months In our clinic, computer tomography angiography 58,5%, magnetic resonance angiography 29,9% and doppler ultrasonograpy 13,2% were used at the time of diagnosis. None of the patients were diagnosed with conventional angiography. The most common angiographic types were type 1 and type 5. At the time of diagnosis the most common arterial lesions were in subclavian arteries (left>right), lef common carotis and the aortic arc. The percentage of the same modality used in our study was 64%. There is limited data about how often the follow-up imaging should be done. However, annually after diagnosis seems optimal. As in 2/3 of our patients, it is important to use the same imaging modality for follow-up. Despite its historical importance, conventinal angiography is not used for disease monitoring.
