目的分析彩色多普勒超声在肝硬化门静脉高压症诊断中的应用价值。方法选取65例肝硬化门静脉高压症患者设为研究组,同期49例体检健康者设为对照组,采用彩色多普勒超声对两组研究对象的脾静脉及门静脉的血流动力学情况进行分析比较。结果研究组患者的门静脉内径值(1.20±0.19)cm与脾静脉内径值(1.45±0.50)cm均显著大于对照组的(0.63±0.43)cm与(0.98±0.35)cm,对比差异有统计学意义(P<0.05)。研究组患者的门静脉血流量与脾静脉血流量的比值(Qsv/Qpv)明显大于对照组,差异有统计学意义(P<0.05)。研究组内门静脉内径值≥1.4 cm的患者的重度食管胃底静脉曲张的发生率(43.08%)明显高于<1.4 cm的患者(18.46%),差异有统计学意义(P<0.05)。研究组内脾静脉内径值≥1.0 cm的患者的重度食管胃底静脉曲张的发生率(44.61%)明显高于<1.0 cm的患者(20.00%),差异有统计学意义(P<0.05)。结论对肝硬化门静脉高压症患者进行彩色多普勒超声检查,能够较为理想地掌握患者的门静脉及其分支的血流动力学情况,对明确诊断及预测食管胃底静脉曲张程度具有十分重要的意义。
Objective To analyze the value of color Doppler ultrasonography in the diagnosis of cirrhosis and portal hypertension. Methods Sixty-five patients with cirrhosis and portal hypertension were enrolled in this study. Forty-nine healthy subjects were enrolled in the study. The hemodynamics of splenic vein and portal vein in two groups were analyzed by color Doppler ultrasonography Compare Results The portal vein diameter (1.20 ± 0.19) cm and the splenic vein diameter (1.45 ± 0.50) cm in the study group were significantly higher than those in the control group (0.63 ± 0.43) cm and (0.98 ± 0.35) cm, respectively Significance (P <0.05). The ratio of portal vein blood flow to splenic vein blood flow (Qsv / Qpv) in the study group was significantly higher than that in the control group, with statistical significance (P <0.05). The incidence of severe esophageal varices (43.08%) was significantly higher in patients with a diameter of more than 1.4 cm in the study group (18.46%) <1.4 cm (P <0.05). The incidence of severe esophageal varices (44.61%) in patients with splenomegaly≥1.0 cm in the study group was significantly higher than that in patients <1.0 cm (20.00%) (P <0.05). Conclusions Color Doppler echocardiography in patients with cirrhosis and portal hypertension can grasp the hemodynamics of the portal vein and its branches more ideally, which is of great significance in the diagnosis and prediction of esophageal varices. .
