摘要
支架内再狭窄(ISR)是限制支架植入术效果并严重影响患者生活质量的主要并发症,血管损伤部位的平滑肌细胞过度增殖是早期ISR形成的主要原因。药物涂层支架和生物可降解支架的问世虽然减轻了ISR危险程度,但是晚期并发症仍处于较高的水平,且生物可降解支架的适用材料还处于探索阶段。本文主要从抑制平滑肌细胞过度增殖的方面,总结平滑肌细胞在ISR进程中的相关机制及治疗手段,希望为临床治疗及实验研究提供思路。
In-stent restenosis(ISR)is a major complication that limits the efficacy of stent implantation and seriously affects patients′quality of life.The excessive proliferation of smooth muscle cells at the site of vascular injury is the main reason for the formation of early ISR.Although the advent of drug-coated stents and biodegradable stents has reduced the risk of ISR,late complications are still at a high level,and the applicable materials of biodegradable stents are still in the exploration stage.This article mainly summarizes the related mechanisms and treatment methods of smooth muscle cells in the process of ISR from the aspect of inhibiting the excessive proliferation of smooth muscle cells,hoping to provide ideas for clinical treatment and experimental research.
