[Laboratory methods of examination of porous vascular prostheses].
The author discusses applied methods of investigation of porous vascular prostheses with special attention to physical methods and proposes some heretofore unused criteria for the evaluation of polyester prostheses such as: quantitative determination of oligomers catalist residues, inor ganic fillers and manufacturer's oil and identification of the degree of crystallization and molecular orientation. The evaluation of these parameters in conjunction with the results of physical, mechanical, hematological, toxicologic and preclinical testing may form the basis for further improvement of vascular prostheses.
