目的评价彩色多普勒超声诊断肝硬化门脉血流改变的临床价值。方法 124例肝硬化患者,将其中60例代偿期硬化者设为研究A组,另64例失代偿期硬化者设为研究B组(其中40例并发食管胃底静脉曲张、脾肿大),另选取同期行健康体检者60例作为对照组,观察并对比三组肝血流参数变化情况。结果研究A、B两组门脉主干内径、门脉截面积、门脉充血指数均比对照组高,且门脉血流速度、门脉血流量比对照组低(P<0.05);失代偿期并食管胃底静脉曲张与脾肿大肝硬化患者脾静脉与门脉血流速度、充血指数、血流量对比差异有统计学意义(P<0.05)。结论彩色多普勒超声应用于肝硬化门脉血流改变的诊断,对肝硬化门静脉高压诊断、病情发展、临床疗效及预后评估均具有重要意义。
Objective To evaluate the clinical value of color Doppler ultrasonography in the diagnosis of hepatic cirrhosis with portal blood flow changes. Methods A total of 124 cirrhotic patients were enrolled in this study. Sixty patients with decompensated cirrhosis were assigned to study group A and 64 patients with decompensated cirrhosis were enrolled in study group B. Forty patients with esophageal and gastric varices, splenomegaly ), And the other 60 healthy subjects were selected as the control group in the same period. The changes of hepatic blood flow parameters were observed and compared. Results The study group A, B portal vein diameter, portal vein cross-sectional area, portal congestion index were higher than the control group, and the portal blood flow velocity, portal blood flow was lower than the control group (P <0.05) The differences of blood flow velocity, congestion index and blood flow in patients with compensated esophageal varices and splenic cirrhosis were statistically significant (P <0.05). Conclusion The application of color Doppler ultrasonography in the diagnosis of portal cirrhosis changes is of great significance for the diagnosis of portal hypertension, the development of the disease, the clinical curative effect and prognosis evaluation.
