Influencing factors for restenosis in patients with Takayasu’s arteritis

Objective To study the predictors and reasons for restenosis in patients with Takayasu’s arteritis（TA） after stenting in order to provide evidence for its clinical intervention. Methods Fifty TA patients who underwent stenting in our hospital from January 2000 to August 2011 were included in this study.The patients were divided into restenosis group and non-restenosis group.Their clinical data and vascular angiographic findings were compared.Independent risk factors for restenosis in TA patients were analyzed using logistic regression model. Results The serum HDL-C level was significantly lower and the implanted stent was significantly longer in restenosis group than in non-restenosis group（P＜0.05）.The proportion of residual stenosis ＞20% and moderate stenosis was higher in restenosis group than in non-restenosis group（P＜0.05）. Conclusion Serum HDL-C level,stent length and residual stenosis may be the influencing factors for restenosis in TA patients.
