Basic studies on autogenized and lysophilized vascular prostheses.
In an effort to improve vascular prostheses, basic studies on tissue-alloplastic prostheses according to a new conception were performed. A medical polyester yarn was used for the construction of three types of prostheses with different mesh and high porosity. The prostheses were autogenized on silicon rods and then lyophilized, resulting in their full intraoperative impermeability, but high biological permeability and antithrombogenicity. Vascular prostheses of this type fulfill many of the requirements of a so-called ideal prosthesis. Analysis of the test examinations provides a basis for elaborating principles for the preparation and production of new tissue-alloplastic prostheses for clinical purposes.
