OBJECTIVE: To investigate the outcome of vascular interventions and the effect of post-interventional immunosuppressive treatment on the occurrence of vascular restenosis in patients with Takayasu's arteritis (TA). METHODS: Forty-two patients with TA who had undergone vascular intervention and had serial angiographies before and after intervention were enrolled. The demographic and clinical data were collected at the time when the interventions were performed, and the intervention modalities and post-interventional medical treatments were evaluated. RESULTS: Sixty-three interventions were performed in 42 patients. Twenty (31.7%) interventions restenosed 24.0 +/- 21.9 months after intervention; the likelihood decreasing as time passed. Estimates of arterial patency after intervention were 90.1% at 1 yr, 75.5% at 2 yr, 68.4% at 3 yr, 61.6% at 5 yr and 49.3% at 10 yr. According to the log rank test, interventions that were performed during the stable stage of the disease (P = 0.039) and those that were followed by treatment with glucocorticoids and immunosuppressive agents (P = 0.044) were independent variables for the maintenance of arterial patency. Their hazard ratios were 0.30 and 0.41, respectively. CONCLUSION: Restenosis occurred in 31.7% of TA patients after intervention. A lower restenosis rate was observed when the vascular interventions were performed at the stable stage and when post-interventional immunosuppressive treatment was implemented.
