摘要 目的 总结主动脉瓣置换术后升主动脉瘤形成的外科治疗经验。 方法 2008年10月至2013年4月郑州大学第一附属医院收治6例主动脉瓣置换术后升主动脉瘤形成患者,其中男2例,女4例;年龄45~63(56.5±3.2) 岁。主动脉瓣置换术后44~82 (59.5±24.3) 个月,均为单纯人工机械主动脉瓣置换术后。5例行单纯升主动脉置换术,1例行David手术。 结果 体外循环时间140~270 (185.2±90.1) min,升主动脉阻断时间60~220 (121.9±78.6) min。6例患者均康复出院。术后将血压控制于120/90 mm Hg以下,应用华法林,维持国际标准化比值(INR) 1.5~2.5。术后均给予琥珀酸美托洛尔25 mg ,每天2次。出院前复查彩色超声心动图(UCG)示:升主动脉内经28~30 mm。术后对6例患者随访3~12个月,门诊复查UCG示:人工血管内径较出院时无明显改变。 结论 主动脉瓣置换术后患者应定期复查UCG,对主动脉内经呈进行性增宽或主动脉瘤形成患者应及早行外科手术治疗。
