METHOD OF COMPARATIVE STUDY OF THE FUNCTIONAL CHARACTERISTICS OF DIFFERENT CONFIGURATIONS

摘要

Method of comparative study of the functional characteristics of different configurations includes coronary anastomosis conducted comparing the characteristics of coronary anastomosis. The study compared the configuration of the coronary anastomosis formed between the one and the same drugs veins and coronary artery pig. Consistently, calibrated using metal probes, determine the diameter of venous and coronary vessels through flexible catheters veins connecting the vertical glass flask, fill flask glycerol solution with distilled water in proportions of 7 to 7.5 parts, respectively, top position the level of liquid in the flask at a height of 1.5 meters on the level of the venous vessels open valve. Venous and coronary vessels preparing to anastomosis, forming a hole the same diameter, creating coronary-venous anastomosis the type of "end-to-side" first method "vein adventitia to adventitia artery." Then create a new type anastomosis "end-to-side" with other methodologies "intima vein to artery intima" between the same vessels that were used to create anastomosis by the first method. Compare speed of fluid and geometric parameters of these two configurations studied coronary anastomoses. Configuration coronary anastomosis, which corresponds to the maximum area of ​​the anastomosis and the maximum speed of the liquid passing through it is the best.
