摘要:
【摘要】 目的 观察新型可降解镁合金支架——MPM植入兔腹主动脉后的降解时间,评估其对血管壁作用特性。方法 取新西兰大白兔12只,分为4组,每组3只。每只实验兔腹主动脉距肾动脉水平下1 cm处植入MPM支架1枚,术后30、60、90、180 d分别对一组实验兔行腹主动脉DSA检查,评估血管情况并分离支架段血管作病理学分析。结果 术后随访期间,12只实验兔均存活良好。病理检查显示30 d时支架形态完整,扩张完全;60 d时少部分支架支杆降解断裂,支撑力较前减弱;90 d时部分支架支杆断裂;180 d时支架几乎完全被吸收,血管内膜稍有增生。取标本肉眼观察,180 d时仅见少量残留支架。根据直线回归分析,计算出支架完全降解天数为182 d。结论 可降解镁合金支架MPM在兔主动脉中失去支撑作用的时间为182 d,可防止晚期血管再狭窄。
