摘要：
The invention relates to medicine, in particular to a method of comparative analysis of functional characteristics of different coronary anastomosis configurations involves the comparison of characteristics of coronary anastomosis performed and is characterized in that compared coronary anastomotic contours are formed between the same specimens of venous vessels and coronary arteries of pig, consequently by means of standardized metal probes diameters of venous and coronary vessels are determined, by means of flexible catheters venous vessel is connected with vertical glass bulb, it is filled with glycerol solution with distilled water in such ratio: 7 parts to 7.5, correspondingly, upper level of fluid in the bulb is arranged at height of 1.5 m above level of venous vessel location, lock valve is opened, venous and coronary vessels are prepared to anastomosing with formation of orifices of equal diameter, venous-coronary end-to-side anastomosis is made by “venous adventitia to arterial adventitia” technique, fluid propagation velocity through coronary anastomosis made between venous and coronary vessel through lock valve of V-adapter in the system of catheters from vertical bulb. Metallic guide is passed through anastomosis by moving through venous vessel and reaching coronary artery, ultrasonic transducer is passed through anastomosis via guide, image of structure of coronary artery, anastomosis itself and venous vessel is obtained by means of apparatus for intravascular ultrasound investigation, fluid from bulb is passed through vessels during the whole this stage. Thereafter longitudinal and transverse anastomosis diameters and total area of anastomosis cross-section are determined on the anastomosis image obtained, then metallic guide and ultrasonic transducer are removed from vessels, all sutures are removed and vessels are separated from each other. New end-to-side anastomosis is made by “venous intima to arterial intima” technique between the same vessels, f
