Determination of Normal Main Portal Vein Diameter using Ultrasonography

Abstract

The portal vein (PV) and hepatic artery forms the liver’s dual blood supply. Sonography is a valuable tool in the assessment of porto-systemic pathologies. This study aimed at determining the mean portal vein diameter based on age, gender and weight. This was a cross-sectional prospective study carried out among apparently healthy adult subjects in Khartoum Hospitals; the data were collected from Khartoum stated hospitals in period from December, 2018 to April, 2019. The result showed no significant difference of PV wit gender at p=0.772 and the mean value was 1.175 ± 0.1559cm. The mean age founded was (43.4±18.7) while the most affected study groups was three groups having the same frequency which are (21.5-32.8, 32.9-44.2, 44.3-55.6) having 21% form study population for each groups. Also female was most affected by this type of measurement having more than 57% from the data.This study found the mean values of PV diameter in apparently healthy adults in our environment to be 0.155 ±0.157mm and that PV diameter positively correlates with anthropometric variables.
