Polyarteritis nodosa (PAN) affects small- and medium-sized arteries but rarely occurs in coronary artery aneurysms and stenosis. For patients with PAN, coronary artery bypass grafting (CABG) can be challenging, especially with respect to graft selection. We performed CABG using a bilateral internal thoracic artery (ITA) graft for a 21-year-old patient with PAN, with successful postoperative outcomes. Arterial grafts have the risk of stenosis in PAN, but the patient's condition was controlled by steroids and immunosuppressants, and angiography showed no stenosis. We decided to use the ITA graft as a bypass conduit and found that long-term follow-up and continuous treatment are necessary.
结节性多动脉炎（PAN）影响小动脉和中等大小的动脉，但很少发生在冠状动脉瘤和狭窄。对于患有 PAN 的患者，冠状动脉旁路移植术（CABG）可能具有挑战性，特别是在移植物选择方面。我们为一名 21 岁的 PAN 患者实施了双侧胸廓内动脉（ITA）移植的 CABG，术后结果成功。在 PAN 中，动脉移植物有发生狭窄的风险，但患者的病情通过类固醇和免疫抑制剂得到控制，血管造影显示无狭窄。我们决定使用 ITA 移植物作为旁路导管，发现需要长期随访和持续治疗。
