目的分析彩色多普勒超声对肝硬化患者门静脉血流改变的评价作用。方法选择2010年1月-2011年4月收治的50例肝硬化患者作为观察组,其中代偿期患者27例,失代偿期患者23例;同时设置健康对照组50名,比较两组的门静脉内径(Dpv)、门静脉平均血流速度(Vpv)、门静脉血流量(Qpv)。结果观察组患者的Dpv增宽,Vpv减慢,Qpv减少,与对照组比较,差异均有统计学意义(P<0.05);且失代偿期患者的改变更为明显,与代偿期患者间差异有统计学意义(P<0.05)。结论彩色多普勒超声检查门静脉血流改变可以对肝硬化患者进行初步确诊。
Objective To evaluate the evaluation of portal vein blood flow in patients with cirrhosis by color Doppler sonography. Methods Fifty patients with cirrhosis who were admitted from January 2010 to April 2011 were selected as the observation group, including 27 compensated patients and 23 decompensated patients. Meanwhile, 50 healthy control subjects were enrolled in this study. Dpv, Vpv and Qpv. Results In the observation group, the Dpv broadening, Vpv slowing, and Qpv decreasing were significantly different from those in the control group (P <0.05). The changes in the decompensated patients were more obvious than those in the compensated patients The difference was statistically significant (P <0.05). Conclusion Color Doppler ultrasound examination of portal vein blood flow changes in patients with cirrhosis can be initially diagnosed.
