彩色多普勒超声对肝硬化上消化道出血患者门静脉血流动力学改变的诊断价值

摘要

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.%目的：探讨彩色多普勒超声(CDFI)对肝硬化上消化道出血门静脉血流动力学的诊断价值。方法：选取96例确诊的肝硬化患者，根据患者有无上消化道出血史，将其分为出血组(45例)和无出血组(51例)；同时选择体检的42名健康志愿者为对照组，利用CDFI对门静脉血流动力学参数进行测定，包括门静脉(PV)及脾静脉(SV)二者的内径、平均血流速度和血流量等，并将3组数据进行比较分析。结果：肝硬化组患者无论出血与否，血管内径均具有明显增加，平均血流速度较慢且门静脉血流量较大，出血组、无出血组与对照组相比，差异均有统计学意义(t=3.579， t=3.670，t=4.750，t=3.951，t=6.116，t=5.371；P＜0.05)。结论：CDFI对肝硬化患者门静脉血流动力学改变的观察无创简便、其检测参数具有重要的诊断价值。
