A 63-year-old woman who underwent surgical correction of a recurrent pulmonary artery aneurysm associated with pulmonary stenosis and regurgitation is reported. On April 1986, she underwent commissurotomy of pulmonary valve, reconstruction of right ventricle out flow tract using a Polystan monocusp patch and pulmonary aneurysmorrhaphy for pulmonary artery aneurysm. Pathological examination of the resected pulmonary arterial wall revealed mucoid degeneration of media and fragmentation of elastic fiber. Nine years after the operation, recurrence of pulmonary artery aneurysm, pulmonary stenosis and regurgitation were recognized. On September 1995, she underwent redo operation with graft replacement of pulmonary artery and pulmonary valve replacement using woven Dacron prosthesis containing a Carpentier-Edwards bioprosthetic valve. We should choose as an initial procedure with graft replacement for pulmonary artery aneurysm with fragility of the pulmonary arterial wall. She is now doing very well at one year and 5 months after the redo operation.
报道了一名63岁女性，她接受了与肺动脉狭窄和反流相关的复发性肺动脉瘤的手术矫正。1986年4月，她接受了肺动脉瓣交界切开术，使用Polystan单瓣补片重建右心室流出道，并对肺动脉瘤进行肺动脉瘤缝扎术。切除的肺动脉壁病理检查显示中膜黏液样变性和弹性纤维断裂。术后9年，发现肺动脉瘤复发、肺动脉狭窄和反流。1995年9月，她接受了再次手术，使用含Carpentier-Edwards生物瓣膜的编织涤纶人工血管置换肺动脉并置换肺动脉瓣。对于肺动脉壁脆弱的肺动脉瘤，我们应选择以人工血管置换作为初始手术方式。再次手术后1年零5个月，她目前情况良好。
