The optimal treatment of coronary stenosis caused by Takayasu arteritis (TAK) remains controversial.
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.
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.
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.
大动脉炎（TAK）所致冠状动脉狭窄的最佳治疗方法仍存在争议。
我们介绍了3例采用创新方法，使用髂外动脉（EIA）补片对年轻TAK患者进行开口处血管成形术的病例。我们确定了影响该技术成功的因素，这些因素与影响其他治疗的因素相似。
所有患者均成功接受了该手术，与传统血运重建方法后的观察结果相比，显示出良好的效果，如血流改善和症状缓解。我们描述了EIA补片血管成形术的技术。
考虑到解剖和病理因素，采用EIA补片进行冠状动脉开口处血管成形术可能为TAK患者冠状动脉开口处狭窄的管理提供更有效和持久的解决方案。然而，尽管该技术具有潜力，但进一步的研究和长期随访对于验证其疗效和安全性至关重要。
