Cases of coronary artery occlusion due to the exclusion of pulmonary artery aneurysm are extremely rare, and there are few reports of surgical treatment. A 60-year-old woman with pulmonary hypertension due to an atrial septal defect and obstruction of the left main coronary trunk due to the exclusion of a giant pulmonary artery aneurysm underwent surgery. The surgery included atrial septal defect closure, tricuspid annulus plasty, pulmonary artery aneurysmorrhaphy, and coronary artery bypass grafting. One and a half years after the surgery, no re-expansion of the pulmonary artery was observed, and the symptoms of heart failure had improved. There are no reports of improvement in pulmonary valve regurgitation by aneurysmorrhaphy in pulmonary artery aneurysm. Surgery for pulmonary artery aneurysm with the exclusion of other organs was effective, and aneurysmorrhaphy for pulmonary artery aneurysm was acceptable.

因排除肺动脉瘤而导致冠状动脉闭塞的病例极为罕见，手术治疗的报道较少。一名 60 岁的女性因房间隔缺损和左主干冠状动脉干阻塞（因巨大肺动脉瘤除外）而导致肺动脉高压，接受了手术。手术包括房间隔缺损闭合术、三尖瓣环成形术、肺动脉瘤成形术和冠状动脉旁路移植术。术后一年半未见肺动脉再扩张，心力衰竭症状好转。没有关于肺动脉瘤中动脉瘤成形术改善肺动脉瓣返流的报道。排除其他器官的肺动脉瘤手术是有效的，
