Objective: To explore the value of color Doppler ultrasound in the diagnosis of portal hypertension liver cirrhosis merged with esophageal variceal bleeding. Methods: The clinical materials of 30 patients with portal hypertension liver cirrhosis merged with esophageal varices who were admitted in our hospital from August, 2014 to August, 2015 were retrospectively analyzed. According to whether there was a history of hematemesis and melena or not before and 3 months after ultrasound examination, and whether was esophageal variceal bleeding or not confirming by the electronic gastroscopy, the patients were divided into the bleeding group (17 cases) and non-bleeding group (13 cases). The color Doppler ultrasonic diagnosis apparatus was used to detect the inner diameter and blood flow rate of splenic vein, portal vein, and left gastric vein. The blood flow volume of splenic vein, portal vein, and left gastric vein was calculated. Results: The inner diameter and blood flow volume of splenic vein in the bleeding group were significantly higher than those in the non-bleeding group, but the blood flow rate was significantly lower than that in the non-bleeding group (P<0.05). The inner diameter of portal vein in the bleeding group was significantly higher than that in the nonbleeding group, but the blood flow rate was significantly lower that that in the non-bleeding group (P<0.05), and the difference of blood flow volume was not statistically significant (P>0.05). The inner diameter of left gastric vein in the bleeding group was significantly higher than that in the non-bleeding group, but the blood flow rate was significantly lower that that in the non-bleeding group (P<0.05), and the difference of blood flow volume was not statistically significant (P>0.05). Conclusions: Color Doppler ultrasound can detect the inner diameter of splenic vein, portal vein, and left gastric vein, and the related hemodynamic indicators, particularly, the inner diameter, blood flow rate, and blood flow volume of splenic vein are effective in predicting the risk of esophageal variceal bleeding.
