目的探讨测量门静脉直径为预测肝硬变食管静脉曲张破裂出血的意义。方法通过B型超声诊断仪测量 141例肝硬变患者的门静脉直径 ,结合胃镜所见 ,分析门静脉直径与门脉高压与食管静脉曲张破裂出血的关系。结果门静脉直径≤ 13mm者 ,门脉高压发生率 4.9% ,出血发生率 12 .2 % ;14～ 16mm者门脉高压发生率 74.7% ,出血发生率 2 0 .5 % ;17～ 2 4mm者门脉高压发生率 10 0 % ,出血发生率 2 9.4%。结论门静脉直径越大 ,门脉高压发生率越高 ,出血危险性越大。提示B型超声测量门静脉直径是诊断门脉高压 ,预测食管静脉曲张破裂出血的一种简便无创的检查方法 Objective To explore the significance of measuring the diameter of portal vein in the prediction of hepatic cirrhosis with esophageal variceal bleeding. Methods The diameter of portal vein in 141 patients with cirrhosis was measured by B ultrasonic diagnostic apparatus. The relationship between portal vein diameter and portal hypertension and esophageal variceal bleeding was analyzed. Results Portal vein diameter ≤ 13mm, the incidence of portal hypertension 4.9%, the incidence of bleeding 12.2%; 14-16mm portal hypertension was 74.7%, the incidence of bleeding 20.5%; 17 ~ 24mm gate The incidence of venous hypertension was 100% and the incidence of bleeding was 9.4%. Conclusions The larger the portal vein diameter, the higher incidence of portal hypertension, the greater the risk of bleeding. Tip B-mode ultrasound portal vein diameter is the diagnosis of portal hypertension, prediction of esophageal variceal bleeding is a simple and noninvasive method
