摘要：Measurement of the diameter of the portal vein may be particularly important in detecting and evaluating patients with portal hypertension as well as some other clinical disorders. But there is paucity of data regarding normal portal vein diameter in northern part of West Bengal, India. Therefore this study was undertaken to throw light into this matter. In this work, we analyzed retrospectively the data regarding portal vein diameter obtained from 2D-Ultrasound of whole abdomen from 500 adults aged between 20 to 50 years of both sexes (male 276, female 224). All the cases met our selection criteria. The results were tabulated and analyzed statistically. The mean diameter of portal vein in male subjects was 10.37 + 1.03 mm and in females it was 9.82 + 1.01 mm. A standard for normal portal vein diameter has been set up which may help clinicians to detect and evaluate several clinical situations.
