Abstract: Objective To evaluate the accuracy of predicting esophageal variceal bleeding （EVB） in patients with liver cirrhosis with three-dimensional reconstruction by multi-slice spiral CT portography （MSCTP） and hemodynamic determination of portal vein by B ultrasonography. Methods The clinical data of 60 patients with cirrhosis who were simultaneously examined by MSCTP and B ultrasonography were collected in this study. The gastroscopy was conducted in patients with EVB. Results In 60 with liver cirrhosis, the actual number of bleeding was 28. When LGV>0.61 cm and PBF>1098.36 ml/min were determined as the cut-off value for EVB, the accurate rates by MSCTP and ultrasonography were 89.29% and 60.71%, respectively（x²=6.095,P=0.029）;26 out of 28 patients with EVB was confirmed by gastroscopy, and no esophageal varices bleeding in the other 2 cases;MSCTP and gastroscopy had no significant difference in predicting EVB （P=1.000） as determined by McNemar test,and Kappa coefficient analysis showed substantial consistency of these two methods （matching coefficient K=0.781,P=0.000）;While there was a significant difference between ultrasonography and gastroscopy in predicting EVB（P=0.012）,and Kappa coefficient analysis showed slight consistency of these two methods （matching coefficient K=0.038,P=0.747）. Conclusion MSCTP can predict EVB,and has a good consistency with gastroscopy.
