彩色多普勒超声预测肝硬化食管静脉曲张出血高危状态的研究

Research of color Doppler Sonography predicting high-danger situation in esophageal varicose hemorrhage related to cirrhosis of liver

目的 评价彩色多普勒超声预测肝硬化食管静脉曲张出血高危状态的临床价值。方法 根据有无出血史将肝硬化患者分为出血组 (30例 ) ,未出血组 (62例 )及正常对照组 (30例 )。结果 出血组Dpv、Vpv、Qsv与未出血组及正常对照组比较有显著性差异 (P <0 .0 1 ) ,Dpv、Vpv、Qsv与食管静脉曲张出血的发生率密切相关 (r =0 .943 ,r =- 0 .60 5 ,r=0 .936 ,P <0 .0 1 ) ,可作为预测食管静脉曲张出血高危状态的有效指标 ,经敏感性、特异性验证 ,筛选Dpv≥1 .5cm ,Vpv≤ 1 2cm/s,Qsv≥ 650ml/min作为预测肝硬化食管静脉曲张出血高危状态的危险值。结论 应用彩色多普勒超声检测门脉血流动力学指标 。

Objective To evaluate clinic value of Color Doppler Sonography predicting high danger situation in esophageal varicose hemorrhage related to cirrhosis of liver.Methods Thirty cirrhosis of liver patients with precious hemorrhage(groupⅠ), 62 cirrhosis of liver patients without precious hemorrhage(group Ⅱ) and 30 control (contrast group) were examined with Color Doppler sonography.Results Dpv,Vpv,Qsv compare to group and contrast group,there is significant change in group Ⅰ in Dvp,Vpv,Qsv are closely correlated with esophageal varicose hemorrhage( r =0.943, r =-0.605, r =0.936).Therefore they can be taken as effective index of predicting high danger situation in esophageal varicose hemorrhage. Dpv≥1.5 cm,Vpv≤12 cm/s,Qsv≥650 ml/min are finally elected to be the threshold value of predicting high danger situation in esophageal varicose hemorrhage related to cirrhosis of liver.Conclusion Color doppler sonography can predict high danger situation in esophageal varicose hemorrhage related to cirrhosis of liver.
