RESUMEN
The purpose was to study the impact of anthropometrical parameters on portal vein diameter and liver size by ultrasound in a subset of Karachi population. Four hundred and fifty nine apparently healthy subjects were included in this cross sectional study. After recording weight and height of each subject, Portal vein diameter and both liver lobes were measured by gray scale ultrasonography. Students T test and ANOVA were applied for statistical analyses. With increasing age, portal vein diameter and right lobe of liver increased significantly [p value < 0.001]. Increase in portal vein diameter was also observed with rise in body mass index [0.8 cm in underweight - 1.1 cm in obese subjects]. Sizes of right and left liver lobes also increased with a rise in body mass index [p value < 0.001 and 0.001]. Gender, however, did not have any effect on portal vein diameter and liver size. Age and body mass index are reliable parameters to consider for avoiding false positive diagnosis of hepatomegaly and portal hypertension. Knowing the right and left liver size with respect to anthropometrical measurements also assist a clinician in selecting a subject for liver transplantation
RESUMEN
Deaths from liver disease have doubled over the last fifteen years. Chronic liver disease and cirrhosis are still the twelfth leading cause of death in the United States. Till date no comprehensive data has been documented in our part of the world which can help a clinician in diagnosing organomegaly. Improved hardware and knowing the exact dimensions of an organ with respect to its anthropometrical measurements can be of great importance in a radiological clinical routine. This article review was the result of recent clinical studies relating to portal vein, liver and spleen normograms in different populations which can show a comparison in accordance with their anthropometrical factors. Data from survey reports, cross-sectional and prospective studies published between the years 2003-2012 on the topic were included. Data searches included both human and cadaveric studies. The data was extracted from online resources of statistic reports, Pub med, THE MEDLINE, Google, Medical and Radiological journals. Sonographical analysis of the effect of anthropometrical measurements on the dimensions of portal vein, liver and spleen can be important markers for evaluation, diagnoses and assessment of portal hypertension, organomegaly and liver transplantation
