Abstract
PURPOSE: The optimal treatment of coronary stenosis caused by Takayasu arteritis (TAK) remains controversial. DESCRIPTION: We present 3 cases in which an innovative approach with an external iliac artery (EIA) patch was employed for ostial angioplasty in young patients with TAK. We determined the factor influencing the success of this technique, which was similar to those having an impact on other treatments. EVALUATION: All patients underwent the procedure successfully, demonstrating favorable outcomes, such as improved blood flow and symptom relief, compared with those observed after traditional revascularization methods. We describe the technique for EIA patch angioplasty. CONCLUSIONS: Considering the anatomic and pathologic factors, coronary ostial angioplasty with an EIA patch may offer a more effective and durable solution for managing coronary ostial stenosis in patients with TAK. However, despite the potential of this technique, further studies and long-term follow-up are essential to validate its efficacy and safety.
