Abstract:
Objective:To differentiate the inflow and outflow channels of gastric varices in cirrhotic portal hypertension patients using multi-slice spiral CT (MSCT), and to assess the relationship between calculable CT volume of gastric varices and the amount of tissue adhesive.
Methods:97 cases with cirrhotic gastric varices who were admitted from November 2013 to August 2017 were selected. The type and shape of gastric varices were observed before tissue glue injection treatment by MSCT. The correlation between CT volume of gastric varices and the amount of tissue adhesive was evaluated by Spearman rank correlation coefficient and Univariate linear regression analysis.
Results:MSCT showed that Le, g type had the highest proportion (54.6%), followed by Le, g, Lg (20.6%). Le, Lg and Lgf type accounted for 17.5%, and 5.2%, respectively, while Lgf+b accounted for 2.1%. On MSCT, varices of the gastric fundus were in the direction from bottom to top, and 75% of the fundus had a large curved side varices combined with gastric and renal shunt. Under the gastroscopy, varices in the small curved side of the gastric fundus from near to far were formless. In addition, varices in the large curved side of the gastric fundus when observed from different angles to the direction of blood flow (reverse gastroscope) were 72.7% (near and far) or 20.5 % (far and near). There was a positive correlation between CT volume (R = 0.97, P < 0.001) and the amount of tissue adhesive (Y1 = 0.35 + 0.65X1, Univariate linear regression equation; ρ = 0.89, P < 0.001, Spearman correlation analysis).
Conclusion:MSCT can recognize the vascular shape and inflow and outflow channels of gastric varices. A positive correlation between CT volume and the amount of tissue adhesive, suggested that the CT volume measurement before treatment could be used as one of the method to predict the amount of tissue adhesive.
