目的探讨肝硬化患者门静脉超声检测与食道静脉曲张程度及上消化道出血间的关系。方法对50例患者使用美国terason HD2000型彩色多普勒诊断仪,探头频率为3.5～5.0MHz,检测后进行分析。结果门静脉直径与食道静脉曲张程度呈高度正相关;食道静脉曲张程度越重,其破裂出血的可能性越大,两者间呈显著正相关;门静脉直径越宽,合并食道静脉曲张破裂出血的百分率越高,两者呈高度正相关。结论门静脉超声测定,可提示门静脉直径大小,可作为预测合并上消化道出血可能性大小的有价值的指标。
Objective To investigate the relationship between portal vein ultrasonography and esophageal varices and upper gastrointestinal bleeding in patients with cirrhosis. Methods 50 cases of patients using the United States terason HD2000 color Doppler diagnostic apparatus, the probe frequency of 3.5 ~ 5.0MHz, after testing for analysis. Results The diameter of portal vein was highly positively correlated with the degree of esophageal varices. The more severe the esophageal varices, the more likely it was to rupture and hemorrhage. The more significant the portal vein diameter was, the percentage of bleeding with esophageal varices The higher the two are highly correlated. Conclusions Portal venous ultrasonography can indicate the diameter of portal vein, which can be used as a valuable index to predict the possibility of upper gastrointestinal bleeding.
