SONOGRAPHIC METHODS OF DIAGNOSIS AND THE INDICATORS IN NORM OF BLOOD FLOW IN UNPAIRED VISCERAL BRANCHES OF THE ABDOMINAL AORTA
The article presents a literature review and analysis of the effectiveness of modern methods of integrated ultrasound in unpaired visceral branches of the abdominal aorta for the diagnosis of visceral blood flow. The basic technical ability to visualize blood vessels, as well as the anatomy of the celiac trunk and mesenteric arteries were in norm. Stated flow indicators and ultrasonic spectral characteristics of the test vessels in healthy subjects are based on published multicenter studies. Results. The physiological characteristics changes of hemodynamic parameters at a test load on the meal and in different phases of respiration, as well as the possible ways of assessing the viability of functional reserves of visceral blood flow are described. These and generalized data on normal sonography of unpaired visceral branches of the abdominal aorta can be used as normal visceral blood flow parameters. The data on the informative method of ultrasound diagnostics in gray-scale and Doppler modes of research in the evaluation of blood flow in the unpaired visceral branches of the abdominal aorta are presented. The possible limitations of ultrasound diagnostic method of research in the study of mesenteric arteries are noted. The authors also analyzed the possi bility and the place of comprehensive sonography in the diagnosis of blood flow in the unpaired visceral branches of the abdominal aorta in chronic diseases of the digestive system.
