Abstract: This paper investigated the value of ultrasound quantitative analysis technology in predicting the bleeding risk of esophageal gastric varices (EGV). 127 patients with cirrhotic portal hypertension were selected as the research objects. After 3 months of follow-up, 2 patients lost contact. According to the presence or absence of EGV bleeding all patients were divided into the occurrence group (60 cases) and the non-occurrence group (65 cases). The severity of EGV severity, Child liver function classification, liver shear wave velocity (LSWV), portal vein diameter (PV), spleen shear wave velocity (SSWV), and spleen index (SI) were compared between the two groups, and the data were statistically analyzed. The results showed that the LSWV, PV, SSWV, and SI in the occurrence group were higher than those in the non-occurrence group (P<0.05). LSWV, PV, SSWV, and SI were positively correlated with EGV severity and Child liver function grade (P<0.05). The combined predictor expression with LSWV (X1), PV (X2), SSWV (X3), SI (X4) as covariates was:Logit(P)=-3.757+2.003×X1+1.989×X2+1.473×X3+1.981×X4, and its AUC for predicting EGV bleeding risk was 0.873 and greater than the original covariates, the predictive sensitivity was 78.33%, and the specificity was 81.54%. It can be seen that the detection of LSWV, PV, SSWV, and SI by ultrasonic quantitative analysis technology could be used as a plan to predict the risk of EGV bleeding, and it can play a certain guiding role in clinical preventive intervention and surgical method.
