摘要 目的:探讨血清组织蛋白酶S(CatS)与胱抑素C(CysC)在脑血管支架术后再狭窄形成过程中的作用。方法:分析2008-2011年23例接受脑血管支架手术患者,术后复查血管造影的时间为3~12个月,就术前、术后3d以及术后3~12个月造影复查时血清CatS与CysC的水平及与血管再狭窄的关系进行分析。结果:本组23例患者,于23根血管上放置23枚支架,随访3~12个月,10例(43.5%)出现了再狭窄,其中超过50%的再狭窄者为5例,余5例再狭窄率介于10%~30%。同时监测术前以及术后血清CatS与CysC的水平,发现23例患者支架术前血清CatS与CysC水平在狭窄组和无狭窄组中差异无统计学意义(P>0.05);支架术后3d两组血清CatS和CysC水平均高于术前,差异均有统计学意义(P<0.05);术后3~12个月复查时再狭窄的10例患者血清CatS与CysC水平高于未狭窄的13例患者,两者比较差异有统计学意义(P<0.01),且血清CatS的上升幅度比CysC的上升幅度更大。结论:血清CatS和CysC增加程度不平衡,可能在一定程度上影响了血管壁细胞外基质的动态平衡,促进再狭窄的形成。
