A 62-year-old man was diagnosed with a giant coronary artery aneurysm associated with immunoglobulin G4 (IgG4)-related disease. He had previously undergone two thoracic operations with sternotomies and abdominal aortic aneurysm repair for IgG4-related aortopathy. We opted for hybrid open and endovascular repair to reduce risk and avoid complications of a resternotomy and extracorporeal circulation. This first successful case of hybrid repair of a giant coronary artery aneurysm shows that the procedure is safe and feasible in patients with IgG4-related vasculopathy. It is critical to carefully monitor these patients for the occurrence of new IgG4-related aneurysms and other manifestations of vasculopathy.

一名 62 岁男性被诊断出患有与免疫球蛋白 G4 (IgG4) 相关疾病相关的巨大冠状动脉瘤。他之前曾因 IgG4 相关的主动脉病接受过两次胸骨切除术和腹主动脉瘤修复术。我们选择了混合开放和血管内修复，以降低风险并避免再切开术和体外循环的并发症。巨大冠状动脉瘤混合修复的首个成功案例表明，该手术在 IgG4 相关血管病变患者中是安全可行的。仔细监测这些患者是否出现新的 IgG4 相关动脉瘤和其他血管病变表现至关重要。
