【摘要】 目的 应用彩色多普勒超声测定胃左静脉来预测食管静脉曲张破裂出血。方法 对28例肝硬化患者(出血组16例，未出血组12例)进行门静脉、胃左静脉的多普勒超声检测(指标包括管径、流速、血流方向及胃左静脉分流指数)，对所测数据进行统计分析。结果 门静脉及胃左静脉出血组管径增粗较非出血组差异均有显著性，但胃左静脉管径增粗较门静脉明显;门静脉血流速度出血组较未出血组及对照组显著减慢，胃左静脉血流速度出血组与非出血组及健康对照组比较显著增快;出血组患者胃左静脉全部呈离肝血流，发生率100%，未出血组有11例呈离肝血流，发生率68.8%:出血组胃左静脉分流指数较未出血组及对照组明显增大，如将胃左静脉分流指数限定值定为0.21时，预测出血的敏感性及特异性分别为83.3%及87.5%。结论 胃左静脉超声检测的各项指标结果提示随门脉压力增高，其出血组与非出血组对比均发生了显著性变化;胃左静脉的管径、血流速度与门静脉比较，具有更显著的变化;胃左静脉分流指数和血流方向的测定在预测出血方面具有更大的价值。

    【Abstract】 Objective To predict esophageal variceal bleeding on utilizing colored doppler sonography in meaˉsurements of left gastric vein.Methods Doppler sonography was used on the portal veins and left gastric vein of the28patients with liver cirrhosis in terms of diameter of blood vessel，velocity of blood flow，direction of blood flow and left gastric vein shunt index.Results The comparison between left gastric vein and portal vein showed that the diameter of blood vessel in bleeding group was noticeablywidened in contrast to that in non-bleeding group ......
