摘　　要：目的评价超声测量胃左静脉在肝硬化食管胃底静脉破裂出血预测中的价值。方法应用三维彩色多普勒对研究对象进行检查,观察胃左静脉及食管胃底静脉曲张的情况,研究胃左静脉与门静脉血流量的变化,并进行统计分析。结果与正常对照组比较,出血组、未出血组胃左静脉最大内径明显增宽(P<0.01)。以胃左静脉最大内径6.5 mm为出血预测标准,预测出血的特异性、敏感性和准确性分别为78.3%、73.5%、76.3%。胃左静脉分流指数截断值定于0.13时,预测出血的特异性、敏感性和准确性分别为82.5%、76.3%、69.8%。结论胃左静脉增宽是肝硬化食管胃底静脉曲张破裂出血的危险因素之一,超声测量胃左静脉最大内径以及检测胃左静脉分流指数具有较高的预测价值。Objective To evaluate the value of ultrasonic measurement of left gastric vein in predcting esophageal variceal bleeding in cirrhosis patients. Methods The study objects were detected by three-dimensional Color Doppler Ultrasonography, the left gastric vein and esophageal varices, portal vein blood flow changes of left gastric vein were ob-served, and statistical analyzed. Results Compared with the normal control group, the left gastric vein diameter of hem-orrhage group widened obviously （ P〈0 . 01 ） . The maximum diameter of the left gastric vein bleeding prediction 6 . 5 mm standard, predicting bleeding specificity, sensitivity and accuracy were 78. 3%, 73. 5%, 76. 3%, respectively, the left gastric vein shunt index cut off value was scheduled for 0. 13, predict bleeding specificity, sensitivity and accu-racy were 82. 5%, 76. 3%, 69. 8%, respectively. Conclusion The dilatation of left gastric vein is a risk factor for por-tal hypertension esophageal variceal bleeding. Ultrasound measurement of left gastric vein diameter and detection of left gastric vein shunt index has a high predictive value.
