目的 观察带瓣人工血管主动脉根部置换术对主动脉根部瘤的治疗效果。方法 收集接受保留主动脉瓣的带瓣人工血管主动脉根部置换术治疗的8例主动脉根部瘤患者的临床资料，回顾手术相关情况及出院后随访情况。结果 住院期间无死亡病例。体外循环时间158～357 min，平均（266.4±60.1）min；主动脉阻断时间136～286 min，平均（200.6±47.9）min。1例患者行深低温停循环。术后并发症包括渗血4例，并发纵隔炎1例。术后随访2～38个月，平均（22.3±12.6）个月；随访期内无死亡病例，1例患者因发生中度主动脉瓣反流而再次接受主动脉瓣置换术。结论 以保留主动脉瓣的带瓣人工血管主动脉根部置换术治疗主动脉根部瘤的中期疗效良好。

Objective To investigate the outcomes of valve-sparing aortic root replacement with Valsalva graft in treatment of aortic root aneurysm. Methods The clinical data of eight patients with aortic root aneurysm undergoing valve-sparing aortic root replacement with Valsalva graft were retrospectively analysed.Results There was no death during the hospital stay. The mean time of cardiopulmonary bypass was (266.4±60.1) min (158 to 357 min), and the mean time of aortic cross clamping was (200.6±47.9) min (136 to 286 min). Deep hypothermic circulatory arrest was performed in 1 patient. The major complications included bleeding in 4 patients and mediastinitis in 1 patient. Patients were followed up for (22.3±12.6) months (2 to 38 months). There was no death during the follow-up. At the end of the follow-up, there was no or trivial aortic incompetence in 7 patients, 1 patient had moderate aortic regurgitation postoperatively and a second aortic valve replacemnt was performed. Conclusion Valve-sparing aortic root replacement with Valsalva graft may yield favourable early and mid-term outcomes in treatment of aortic root aneurysm.
