For the diagnosis of heart diseases, several instrumental informative research methods are used, which allow to determine with a high degree of accuracy the presence of the morphological substrate of some organ pathologies. Among these methods, echo cardiography and coronarography are most commonly used. The feedback of the target specialists regarding them allows us to highlight these methods as the main ways to establish the severity of the pathology. At the same time, each doctor pursues the principle that confirmation of the diagnosis, realized instrumentally, is the main task of the doctor, because based on the results of a specific study, it is possible to plan adequate therapy or rehabilitation.
Coronarography is an invasive diagnostic method with high specificity and informativeness to coronary arteries of the heart. It allows with great accuracy to identify the growth of atherosclerotic plaques, as well as to assess the degree of occlusion of a particular vessel or its section, which will have prognostic value. Also, coronarography, the reviews of doctors about which argue the rationality of its use, allows you to clearly differentiate the morphology of a particular plaque or blood clot, to recognize signs of their destruction, to find out the localization relative to the walls of the vessel.
The coronarography technique is quite simple and is associated with a small amount of time spent. Initially, the site near the introduction of the introducer, the channel for the insertion of the catheter, is chopped with a local anesthetic solution, to which a small fraction of adrenaline is added to reduce the resorption of the catheter. A radiopaque material is fed through the catheter, filling the coronary arteries, extending from the aorta until its arc is formed. It, spreading with arterial blood, enters the smaller branches of the arterial vascular bed of the heart.
After filling the catheter, pictures are taken, the results of which are processed using computer programs, after which the result is visualized. Moreover, in this form, coronary angiography, reviews of which by the medical staff favorably distinguishes this method from other instrumental methods for examining the heart, is the most optimal way to visualize both the coronary arteries themselves and their branches that deliver blood to the myocardial sites.
In this case, the processed result of coronarography allows you to differentiate areas with contrast, which are x-ray tissue, that is, absorbing radiation. Blood has such properties, while the walls of the artery do not stand out, but have a dark edge. By its curvature, as well as by the thickness of the liquid strip stained with contrast, it is possible to judge the width of the lumen of the arterial vessel in a controlled area. This information is important for the diagnosis of vascular pathologies, atherosclerosis, as well as the planning of cardiac surgery.
With a procedure such as coronarography, complications are quite rare. This is partly due to injury to the vessel wall, as well as the possibility of infection of the puncture site, the development of phlebitis. Therefore, the question of whether coronarography has contraindications for conducting is definitely answered. It is contraindicated in the presence of inflammatory diseases in the places of the alleged puncture of the vessel, as well as in the syndrome of a systemic inflammatory response. Also, the use of coronarography for allergic reactions to the components of the solution used as a contrast is not allowed. At the same time, the opinion of many doctors regarding such a diagnostic procedure as coronarography, reviews characterize on the positive side. Similar trends are followed by patients of cardiological hospitals.
