Abstract

The perfusion technique to measure the relative adhesive and thrombogenic indices of vascular prostheses by a quantitative scanning electron microscopy has been described. To normalize the experiments with different samples of plasma we compared the adhesive and thrombogenic properties of the analyzed prostheses with those of normal and denuded human umbilical vein. The results indicate that adhesive and thrombogenic indices of Dardik, Bakulev and Gore-Tex grafts approximate to those of the non-damaged umbilical vein, while the same indices of Solcograft-P prostheses are considerably higher. The method may be useful for standardizing the properties of new prostheses and bioimplants for cardiovascular surgery.

摘要

已经描述了通过定量扫描电子显微镜测量血管假体相对粘附和血栓形成指数的灌注技术。为了使不同血浆样本的实验标准化，我们将分析的假体与正常和剥脱的人脐静脉的粘附和血栓形成特性进行了比较。结果表明，达迪克、巴库列夫和戈尔-特克斯移植物的粘附和血栓形成指数接近未受损脐静脉的指数，而索尔科移植-P假体的相同指数则高得多。该方法可能有助于标准化心血管手术中新假体和生物植入物的特性。
