title: Takayasu's arteritis: clinical features and outcomes of 125 patients in China.
abstract: Takayasu's arteritis (TA) is a chronic inflammation that frequently involves the aorta and its major branches. The clinical features of TA vary in different ethnic populations. The objective of this study is to characterize the clinical features, angiographic findings, and response to treatment of patients with TA in Changhai Hospital, Shanghai, China. The hospital records of 125 patients diagnosed with TA were retrospectively evaluated. Eighty patients were followed for a median duration of 36 months. Females (86.4%) were most frequently affected. The mean age at onset was 26.9 years. Constitutional symptoms were present in only 38.4% of patients. The most common clinical finding was pulse deficit. Histological findings from 12 clinically inactive patients showed active lesions in 58.3%. Angiographic classification showed that type I was the most common, followed by type V and IV. Type I was more common in adult patients than in pediatric patients. Although immunosuppressive treatment induced remission in most patients, over 90% of those who achieved later remission relapsed. Both bypass procedures and angioplasty showed high rates of initial success, but restenosis occurred in 34.7% of bypass procedures and 77.3% of angioplasty procedures. Eight patients died during the follow-up period with the main cause of death being congestive heart failure. Constitutional symptoms were not frequent in our study. Correlation between the clinical assessment of disease activity and histologic findings is often poor in TA. Angiographic findings showed that type I was the most common in our study. Over the longer term, the outcomes of revascularization were superior to angioplasty.
