Restenosis after endovascular PTA/stenting for supra-aortic branches in Takayasu aortitis: report of three cases and review of the literature.

Abstract

Recently, endovascular management has been reported as a feasible option for Takayasu aortitis. However, few papers have focused on restenosis in the follow-up, and therefore, it is important to predict high-risk cases for restenosis after endovascular treatment. We herein report three cases with Takayasu aortitis showing repeated restenosis after endovascular percutaneous transluminal angioplasty (PTA)/stenting and discuss its clinical implications with a review of the literature. We should keep in mind that endovascular PTA/stenting for Takayasu aortitis does not always keep the patency of the affected vessels, and severity of the stenosis and/or uncontrollable systemic inflammation could be a risk factor for restenosis. Therefore, careful follow-up under strict control of inflammation is mandatory. Overall, this method is effective as an initial treatment since repeated PTA is available until collateral supply develops.
