目的 采用豬右乳內動脈在非體外循環(huán)下行選擇性心中靜脈動脈化(CVBG),評價其療效并對其機制進行初步探討?!》椒ā?2只右冠狀動脈重度彌漫性狹窄的中華實驗小型豬 [雌雄不限,月齡7~10個月,體重(40±5) kg]按隨機數字表法分為兩組,每組6只。實驗組:采用右乳內動脈行CVBG;對照組:單純開胸。右冠狀動脈內膜剝脫術后8周對兩組豬行超聲心動圖檢查,術后6 h、3個月行冠狀動脈造影、移植血管血流量測定及超聲心動圖檢查,術后3個月處死動物前行非放射性彩色微球檢測,觀察兩組豬心功能、移植血管血流量、移植血管通暢性和缺血心肌微循環(huán)再灌注情況?!〗Y果 右冠狀動脈內膜剝脫術后8周,兩組左心室功能無差異。實驗組行CVBG術后6 h和3個月心臟收縮和舒張功能均較對照組有所改善(術后3個月射血分數 :52%±6% vs.44%±5%, t=-2.500,P=0.031)。實驗組術后6 h、3個月移植血管血流量分別為(44.50±5.86) ml/min、(43.33±5.01) ml/min(P=0.718),搏動指數(PI)分別為0.73±0.14、0.80±0.14 (P=0.858)。實驗組術后6 h和3個月行冠狀動脈造影顯示:乳內動脈橋及吻合口均能順利通過造影劑,無狹窄;施行CVBG后,經非放射性彩色微球法檢測可見心肌各層的血流量均較對照組有所增加[穿壁心?。?(0.33±0.05) ml/(g ? min) vs.(0.19±0.03) ml/(g ? min),P<0.05],尤其是心內膜下心肌?!〗Y論 采用乳內動脈行CVBG,可改善心肌缺血的近、中期療效,其機制可能是通過改善心肌微循環(huán)而實現的。
