冠状动脉旁路移植血管的生物学特性研究进展

The Development of Vascular Reactivities of Arteries for Coronary Artery Bypass Grafting

目前临床上常用的血管桥有乳内动脉、桡动脉和大隐静脉,3种桥血管不同的组织结构、对血管活性物质不同的反应性和血管壁平滑肌受体分布的不同,与移植血管痉挛的发生率及近远期通畅率密切相关,是关系到冠状动脉旁路移植术手术成败的重要因素之一。对桥血管结构、功能的了解,有助于临床合理选择和应用合适的移植血管,为提高冠状动脉旁路移植术的近远期通畅率提供一定的理论依据现综述如下。

Nowadays, clinicians generally use the internal mammary artery, radial artery and the great saphenous vein for coronary artery bypass grafting. Different vascular construction, different reaction to vascular reactivities and different distribution of vascular smooth muscle receptors are all factors influencing spasms and early and late patency rate of bypass grafting. A clear understanding of the construction and function of bypass grafting contributes to the selection of a suitable bypass grafting method, and to improving its early and late patency rate.
