    Abstract:
    The possibility of studying the hemodynamics in the visceral arteries of the abdominal aorta by duplex scanning was demonstrated. The results of examination of 30 healthy persons are discussed. Characteristic features of the blood flow spectrogram of the celiac trunk and superior mesenteric artery were revealed. According to the spectrogram, the flow of blood in the celiac trunk is characterized by rapidly increasing peak systolic rate and slowly diminishing diastolic rate to approximately 1/3 of the maximal value of systole. The character of the blood flow in the superior mesenteric artery is distinguished by a lesser peak systolic rate and the presence of a short-lived reverse rate before the sloping diastolic curve. Normal values of the blood flow volume rate were determined, it was 649 +/- 25.4 ml/min in the celiac trunk and 395 +/- 20.5 ml/min in the superior mesenteric artery. Among the advantages of the duplex scanning method are noninvasiveness and safety and the possibility of dynamic study of the hemodynamic parameters.
