    Abstract:
    Purpose: To evaluate the safety and efficacy of endovascular treatment for iliac artery stenosis caused by Takayasu arteritis (TA). Methods: Twenty-three consecutive TA patients (mean age 28.6±9.5 years; 17 women) with 30 iliac artery stenoses underwent percutaneous transluminal angioplasty (PTA) and selective stent implantation between January 2007 and December 2016. All had claudication (Rutherford category 2 or 3). The changes in the Rutherford category, ankle-brachial index (ABI), 6-minute walking capacity, and adverse events were assessed. Results: The success rate of endovascular therapy for iliac artery lesions was 93.3% (28/30). Guidewires could not cross either lesion in a patient with bilateral stenoses. Twenty-four lesions were treated by PTA alone and the other 4 lesions with provisional stents. One patient had a puncture site hematoma. Over an average of 4.8±3.3 years, 18 patients remained asymptomatic or had mild intermittent claudication. The other 4 patients developed moderate to severe intermittent claudication due to progression of a previously existing iliac lesion (n=1) or restenosis (n=3); all 4 underwent PTA. At the last follow-up, improvements were seen in the ABI (0.95±0.12 vs 0.51±0.22, p<0.001), 6-minute walking capacity (409.5±46.1 vs 272.6±32.3 m, p<0.001), and the Rutherford category of 22 patients. One patient died of a hemorrhagic stroke at 27 months due to uncontrolled hypertension. Conclusion: Endovascular therapy was safe and effective in treating TA patients with iliac artery stenosis, with good clinical outcomes in the long term.
