目的检测食管胃底静脉曲张患者门静脉血流速度。方法使用彩色多普勒超声和胃镜对80例肝硬化和24例慢性肝炎患者进行门静脉血流速度测定和静脉曲张程度检查。结果 24例慢性肝炎、33例轻度静脉曲张、12例中度曲张和35例重度曲张患者门静脉血流速度分别为16.6±3.7cm/s、16.5±3.7cm/s、15.4±5.1cm/s和14.7±4.0cm/s,重度患者血流速度明显减慢(P<0.05)。结论食管胃底静脉曲张程度的轻重与门静脉血流速度呈负相关。
Objective To detect the portal vein blood flow velocity in patients with esophageal varices. Methods 80 patients with cirrhosis and 24 patients with chronic hepatitis were examined by color Doppler ultrasound and gastroscope for the determination of portal venous flow velocity and varicose vein degree. Results The portal venous flow velocities in 24 patients with chronic hepatitis, 33 with mild varices, 12 with moderate varices and 35 with severe varices were 16.6 ± 3.7cm / s, 16.5 ± 3.7cm / s and 15.4 ± 5.1cm / s, respectively And 14.7 ± 4.0 cm / s, respectively. The blood flow velocity of severe patients was significantly slowed down (P <0.05). Conclusion The severity of esophageal varices has a negative correlation with portal blood flow velocity.
