摘要:
【摘要】 目的 比较用于评估治疗急性缺血性脑卒中的介入取栓器械的血栓模型。为介入机械取栓器械的研制、评估提供更为科学的血栓模型。方法 复制Kan及Gralla的可透X线血栓模型,自制聚氯乙烯管内自发凝固成型可透X-线红色血栓模型(spontaneous non?蛳 radiopaque tube red clots,SNTR)及聚氯乙烯管内自发凝成型可透X-线的白色血栓模型(spontaneous non?蛳 radiopaque tube white clots,SNTW)。用弹性实验,拉伸实验评价比较血栓模型的机械力学性能。用HE染色评价血栓模型的组织结构。结果 制备出SNSW(Kan模型)、TNTR(Gralla模型)、SNTR及SNTW 4种机械特性完全不同的可透X-线血栓模型,在24 h及1和2周的弹性实验(度)结果分别为SNSW:5.00 ± 4.47,4.16 ± 3.76,5.83 ± 6.64;TNTR:19.33 ± 6.05,16.66 ± 4.08,19.16 ± 9.70;SNTR:10.00 ± 7.07,7.50 ± 6.89,13.33 ±4.08;SNTW:87.5 ± 2.73,81.66 ± 6.83,88.33 ± 4.08。拉伸实验(cm)的结果分别为SNSW:4.43 ± 0.38,4.67 ± 0.29,4.60 ± 0.31;TNTR:3.79 ± 0.13,3.91 ± 0.11,3.91 ± 0.16;SNTR:3.25 ± 0.15,3.46 ± 0.10,3.33 ± 0.27;SNTW:4.22 ± 0.18,4.40 ± 0.32,4.11 ± 0.15。结论 SNSW,TNTR,SNTR及SNTW为4种机械性能不同的血栓模型,根据研究目的及器械的取栓原理从4种血栓模型中选用或联合其中几种评估介入取栓器械的效能更为合理。
