彩色多普勒超声对门脉高压食管静脉曲张出血的诊断价值

Diagnostic value of portal hypertension high risk esophageal varices in liver cirrhosis patients by color Doppler ultrasound

目的评价门脉血流动力学参数在预测肝硬化食管静脉曲张高危患者中的作用。方法对85例肝硬化患者行胃镜和彩色多普勒超声检查,使用单因素分析和多元分析对门脉血流动力学指标与确认的食管静脉曲张的存在和规模间的关系进行评估。结果食管静脉曲张组的肝动脉阻力指数、脾动脉阻力指数、充血指数、门脉高压指数较无食管静脉曲张组大,肝血管指数较无食管静脉曲张组小,食管静脉曲张重度组的肝动脉阻力指数、脾动脉阻力指数、脾脏长径、充血指数、门脉高压指数较轻-中度组大,肝血管指数较轻-中度组小,差异均有统计学意义(P<0.05)。结论彩色多普勒超声对门脉高压食管静脉曲张出血有较高的诊断价值。

Objective To evaluate the effect of portal hemodynamie parameters in liver cirrhosis patients with esophageal varices （EV）. Methods Eighty - five patients with liver cirrhosis were examined by gastroscope and color Doppler uhrasonography, The relationship between portal hemodynamics and the presence and size of EV was evaluated by single factor analysis and multivariate analysis. Results Hepatic arterial resistance index, splenic artery resistance index, congestion index and portal hypertension index in EV group were higher than those in without EV group, hepatic blood vessel index was lower than that in without EV group. While the hepatic arterial resistance index, splenic artery resistance index, spleen length, congestion index and portal hypertension index in severe group of EV group were higher than those in mild - moderate group, while the hepatic blood vessel index was lower than that in mild - moderate group, there was significant difference between the two groups （ P 〈 0.05 ）. Conclusion Color Doppler ultrasound has important value in diagnosis of portal hypertension high risk esophageal varices in liver cirrhosis patients.
