[Effect of intra-aortic balloon counterpulsation on thrombocyte ultrastructure and functional properties].
Ultrastructure and function of blood platelets have been examined after intraaortic balloon counterpulsation in 9 dogs. Intraaortic balloons made of "polyurethane" (Experiment I) or "biomer" plastic (Experiment II) were used. An increase in the number of platelet microforms due to the fragmentation of the normal-sized platelets has been noted along with the ultrastructural signs of platelet activation, degranulation and alterations of plasma membrane structure. The above changes were less pronounced in experiment II.
