摘要

冠狀動脈繞道手術(CABG)移植物有各種不同的選擇，靜脈移植物包括：隱靜脈、臍靜脈、頭靜脈、同種移植靜脈；動脈移植物則有：內乳動脈、右胃網膜動脈、腹壁下動脈及橈動脈(radial artery; RA)等。由於動脈移植物較靜脈移植物不易粥狀硬化，內乳動脈的通暢率也已被證實比隱靜脈高；因此取動脈移植物作冠狀動脈繞道手術已是目前的趨勢。
其中純動脈因取得技術改進及預防和治療動脈痙孿藥物的使用，使其五年通暢率普遍提高，而再度成爲冠狀動脈繞道手術移植物的另一個選擇。

There are many kinds of graft could be utilized for coronary artery bypass grafting (CABG). The venous grafts that have been used are the saphenous vein, umbilical vein, cephalic vein, and homograft vein. On the other hand, the arterial conduits that now are accepted in coronary artery surgery are the internal mammary artery (IMA), right gastroepiploic artery (RGEA), inferior epigastric artery (TEA), and radial artery (RA). Using the arterial conduits as coronary artery bypass grafts becomes a new trend because of the arterial conduits are more free from vulnerability to atherosclerosis than the venous conduits, and the IMA is superior to the saphenous vein in the long-term patency rate hat! been proved also. The five-year patency rate of the radial artery grafts was elevating because of improved harvesting techniques and utilization of anti-spasmodic to prevention and management of spasm arterial grafts. The better patency rate led to the emergence of the radial artery as a graft in CABG again.
