摘要:目的 總結(jié)非原位主動脈瓣置換術(shù)( AVR)的方法和療效。方法 2008年 3月至 2010年 12月第二軍醫(yī)大學長海醫(yī)院收治 5例主動脈瓣環(huán)嚴重毀損患者,男 4例,女 1例;平均年齡 46.3(38~53)歲。 AVR術(shù)后并發(fā)嚴重瓣周漏再次手術(shù) 4例(白塞氏病 2例、大動脈炎 2例),嚴重主動脈瓣感染性心內(nèi)膜炎 1例。術(shù)中發(fā)現(xiàn)主動脈瓣環(huán)嚴重毀損,無法施行常規(guī) AVR,改行非原位 AVR,即將人工主動脈瓣環(huán)固定的位置提高到毀損的主動脈瓣環(huán)以上,固定人工瓣環(huán)的縫線從主動脈腔外進針、腔內(nèi)出針。必要時行冠狀動脈旁路移植術(shù)( CABG)。結(jié)果 5例手術(shù)患者均順利康復(fù)出院,無出血再次手術(shù)或其它并發(fā)癥。術(shù)后 5例患者均獲得隨訪,生存良好,心功能分級(NYHA)Ⅰ~Ⅱ級;分別于術(shù)后 6個月( 4例)、 1年(2例)和 3年(1例)行主動脈心臟三維 CT成像( CTA)檢查,均未見有主動脈根部瘤或假性動脈瘤形成,顯示左心室流出道延長,左、右冠狀動脈形態(tài)良好。心臟超聲心動圖檢查均未發(fā)現(xiàn)有瓣周漏。結(jié)論 對主動脈瓣環(huán)毀損嚴重的患者采用非原位 AVR,人工瓣膜固定可靠,可以防止術(shù)后并發(fā)瓣周漏或根部假性動脈瘤。
