Background: Takayasu arteritis (TA) is a chronic vasculitis of unknown etiology involving the aorta and its main branches and it is related to arterial hypertension, congestive heart failure, and disabling claudication. However, the efficacy and safety of endovascular stent implantation at the aorta have not been investigated clearly. Therefore, we evaluated the usefulness of stent implantation at the aorta in Takayasu arteritis patients in our single center registry. Method: Eleven patients were treated with percutaneous transluminal angioplasty (PTA) with stent implantation at the aorta from January 2001 to May 2007. All of the enrolled patients were female(mean age: 48 years, range : 33-65 years). The indication was disabling claudication or uncontrolled hypertension. The patency of the stent during the follow-up period was evaluated with ankle-brachial index (ABI) and aorta computerized tomography (CT) scan. Results: The mean clinical follow-up duration was 43 months (range: 3-214 months). The stent implantation was done in 11 patients. Although PTA without stent implantation was performed in only one patient, the patient underwent stent implantation 2 months after the procedure due to aortic dissection. The 9 of 11 patients with the stent were evaluated with aorta CT scan at mean 12 months after the procedure and none of them developed in-stent restenosis. All the patients have not shown clinical evidence of stent restenosis such as uncontrolled hypertension or claudication during the follow-up period. Conclusion: PTA with stent implantation is safe and feasible in the aortic lesion of patients with TA.
