彩色多普勒超声对肝硬化上消化道出血门静脉血流动力学改变的诊断价值

Diagnosis value of color Doppler ultrasound on portal hemodynamics in cirrhosis of upper gastrointestinal hemorrhage

目的 探讨彩色多普勒超声对肝硬化上消化道出血门静脉血流动力学改变的诊断价值.方法 选择商丘市第一人民医院收治肝硬化患者86例,依据有无出血史将其分为出血组（50例）与无出血组（36例）,另选择体检健康人群86例作为对照组,患者行彩色多普勒检测门脉血流动力学的参数.结果 出血组较其他两组静脉内径及血流量显著增加,分流指数显著升高,而血流速度显著减慢,差异有统计学意义（P＜0.05）.结论 上消化道出血与脾静脉、门静脉血流动力学的变化密切相关,彩色多普勒可动态监测各项指标,对于预判门静脉高压引起的消化道出血及肝功能状况诊断具有重要意义,值得临床推广应用.

Objective To investigate the diagnostic value of color Doppler ultrasound on the changes of portal hemodynamics in cirrhosis of upper gastrointestinal hemorrhage.Methods Eighty-six patients with liver cirrhosis patients were selected from the First People＇ s Hospital of Shangqiu,including 50 cases of hemorrhage（bleeding group） and 36 cases without bleeding（non-bleeding group）.Eighty-six healthy person were chosen from physical examination as the control group.Color Doppler was used to measure the portal blood flow of all the objects.Results Compared to the other two groups,vein diameter and blood flow increased,shunt index significantly increased,and the velocity of blood flow slowed down significantly in the bleeding group,the differences were significant （P 〈 0.05）.Conclusions The changes of portal hemodynamics is closely correlated with upper gastrointestinal hemorrhage,each index can be dynamidy monitored by color Doppler,and can be used as a valuable means of prediction of gastrointestinal bleeding caused by portal hypertension and liver function,so it is worthy to be popularized in the clinical application.
