摘要

A method of estimating quantitative indicators of blood flow in the inferior mesenteric artery (NBA) in colorectal cancer patients, characterized in that the Doppler ultrasound NBA performed during surgery, this sensor is applied to a sterile surgical wound in the abdominal aorta in the NBA output projection 2-3 cm above the bifurcation of the aorta in the thickness mesentery, deduce aortic cross-section, wherein in the artery B-mode is defined as a rounded structure hyperechoic lumen walls and cavities anehogennoe and; then carried duplex scanning NBA using color Doppler and pulsed-wave Doppler, research quality indicators: determining a shape of the Doppler curve, the type of spectrum of Doppler frequencies, and quantitative blood flow indicators, which normally are determined in the ranges: systolic velocity - from 49 to 137 cm / s, diastolic velocity - from 2.1 to 45.9 cm / s, the resistivity index - from 0.67 to 1.0, the pulsation index - from 0.15 to 12.5, NBA evaluated both with a high peripheral artery resistance, and in detecting deviations quantitative characteristics determine the absence of the main barrel and are selected NBA embodiment surgery based on blood supply relegated card graft.
