Abstract

Choosing appropriate bypass conduits is important in the consideration of long-term outcomes after surgical revascularization. When deciding on a grafting strategy, attention should be given to technical, anatomic, and angiographic determinants of conduit properties, as well as the clinical characteristics of the patient. The aim of the study was to present a current review of available choices of conduits in coronary artery bypass surgery. To date, only 4 conduits have proven to be effective: the saphenous vein (SVG), the internal mammary arteries (IMAs), the radial artery (RA), and the right gastroepiploic artery (RGEA). The IMA has unique biological properties that confer protection to intimal growth and atherosclerotic plaque formation, making it the conduit of choice for coronary artery bypass grafting. SVG exhibits a lower patency rate than those of IMAs. The RGEA allows revascularization of the inferior wall but is less commonly used, given that it is more prone to spasms.
冠状动脉搭桥术中导管的选择
选择合适的旁路导管是考虑手术血运重建术后长期预后的重要因素。在决定移植策略时,应注意导管特性的技术、解剖和血管造影决定因素,以及患者的临床特征。本研究的目的是对目前冠状动脉搭桥手术中可用导管的选择进行综述。迄今为止,只有4条导管被证明是有效的:隐静脉(SVG)、乳腺内动脉(ima)、桡动脉(RA)和右胃网膜动脉(RGEA)。IMA具有独特的生物学特性,可保护内膜生长和动脉粥样硬化斑块的形成,使其成为冠状动脉旁路移植术的首选导管。SVG的通畅率低于ima。RGEA允许下壁血运重建,但不常用,因为它更容易发生痉挛。
