Abstract:
Objective:To investigate the value of color doppler flow imaging (CDFI) in the diagnosis of liver cirrhosis upper gastrointestinal bleeding in portal vein hemodynamic changes. Methods: 96 cases of patients with liver cirrhosis were selected who were diagnosed in our hospital, according to the history whether patients had a gastrointestinal bleeding or not. They were divided into bleeding group(45 cases) and no bleeding group(51 cases). At the same time, we chose the hospital physical examination center of 42 cases of healthy volunteers as a control group, using color doppler flow imaging portal venous blood flow mechanics parameters, including diameter, average blood flow velocity and blood flow of portal vein(PV) and splenic vein(SV) and compare the data of the three groups.Results: Compared with control group, the patients with liver cirrhosis, the blood vessel diameter have increased whether bleeding or not. The average blood flow velocity is slower and PVF is larger, and the differences between them are statistically significant(t=3.579,t=3.670,t=4.750,t=3.951,t=6.116,t=5.371;P<0.05). Conclusion: The clinical application of color doppler flow imaging(CDFI) in patients with cirrhosis portal hemodynamic change is not only simple noninvasive, and there is important diagnostic value in the detecting parameters.
