An aberrant right subclavian artery (ARSA) is a rare arterial anomaly. Although a few cases of total endovascular repair for the ARSA aneurysm have been previously reported, anatomical limitations and the possibility of endoleaks remained. In this case, we created 4 holes on the stent graft for each cervical branch, with reference to the preoperative computed tomography findings. This approach might enable us to repair all types of thoracic aortic aneurysms with ARSA with each anatomical feature.
异常右锁骨下动脉（ARSA）是一种罕见的动脉异常。尽管此前已有少数 ARSA 动脉瘤的完全血管内修复病例报告，但存在解剖学限制和内漏的可能性。在这种情况下，我们根据术前计算机断层扫描结果，在支架移植物上为每个颈支创建了 4 个孔。这种方法可能使我们能够根据每个解剖学特征来修复所有类型的 ARSA 胸主动脉瘤。
