大隐静脉旁路移植血管内膜增生影响因素研究进展

摘要

大隐静脉旁路移植血管再狭窄可严重影响冠状动脉旁路移植术的远期疗效.内膜增生是静脉旁路血管再狭窄的主要原因和基础病变.与动脉内膜增生相比,静脉内膜增生形成具有独特的影响因素.本文就静脉旁路移植血管内膜增生的影响因素作简要综述.%Objective Saphenous vein graft(SVG) re-stenosis has an severe adverse effect on the long-term prognosis of coronary artery bypass grafting.Intimal hyperplasia(IH) is the prima~ cause and basic pathology of SVG re-stenosis.Comparing to arterial graft IH,different factors promotc IH of SVG.In this review,we summarized the special factors promoting IH of SVG.
