Correlation of portal vein diameter and splenic size with gastro-oesophageal varices in cirrhosis of liver

摘要

This study was conducted to find out the correlation of portal vein diameter and splenic size with gastro-oesophageal varices indiagnosed cases of cirrhosis of liver.Eighty-two patients with cirrhosis of liver were selected for the study. Ultrasonography was performed in all cases to note theportal vein diameter and splenic size. Oesophago-gastro-duo denoscopy was done to detect presence of varices with grades.In the study it was found that twenty patients had no varices (grade 0) and the rest sixty-two patients developed varices. Averageportal vein diameter of patients without gastro-o esophageal varices was 11.545 ± 1.514 mm and of patients with varices 13.998± 1.123 mm. The difference was statistically significant (p < 0.05). Average spleen size of patients without gastro-oesophagealvarices was 13.129 ± 1.102 cm and with varices 14.997 ± 1.992 cm. This variation was also statistically significant (p < 0.05). Therewas a positive correlation between grading of oesophageal varices and portal vein diameter (r = 0.707; p < 0.001) and betweensplenic size with oesophageal grades (r = 0.467; p < 0.001).The study portrays that with increase in portal vein diameter and splenic size, the chance of formation of gastro-oesophagealvarices also increases and a positive correlation exists.Thus, measurement of portal vein diameter and splenic size byultrasonography is a non-invasive predictive indicator of the development of gastro-oesophageal varices in cirrhosis of liver
