为探讨应用B超测定门静脉宽度在预测因门脉高压所致出血的危险性方面的价值,对165例住院的肝硬化患者进行了前瞻性临床研究,结果表明,门静脉直径与上消化道出血危险性呈正相关.当肝门静脉直径超过16mm,脾门静脉直径超过10mm时应高度警惕出血的危险性.
To investigate the value of B-mode ultrasonography in predicting the risk of bleeding due to portal hypertension, a prospective clinical study of 165 hospitalized patients with cirrhosis was performed. The results showed that the portal vein diameter and upper gastrointestinal bleeding risk Sexual positive correlation.When the diameter of the hepatic portal vein more than 16mm, splenic portal vein diameter of more than 10mm should be highly alert to the risk of bleeding.
