Background: There are many causes of the portal vein (PV) disease and these include portal hypertension (PHT), PV thrombosis, PV gas and PV stenosis/obstruction. PHT is a common clinical presentation of portal venous disease with multiple causes and several sequelae. There is a need for an imaging parameter that will aid early diagnosis of PHT since portal pressure monitoring devices are not available in most tertiary hospitals in Nigeria. Aims and Objectives: To determine the normal values of PV parameters using triplex ultrasound (US) among adults in Zaria, Nigeria. Settings and Design: This prospective study was conducted over a period of 6 months between November 2011 and May 2012 at the Radiology Department of Ahmadu Bello University Teaching Hospital, Zaria. Materials and Methods: Following an overnight fast, US scan was performed on 186 eligible participants. The diameter, cross-sectional area (CSA) and flow velocity of the PV were obtained. Results: The PV parameters obtained were as follows (mean ± standard deviation): PV diameter, 1.09 ± 0.22 cm (range: 0.87-1.31); CSA, 1.10 ± 0.203 cm 2 (range: 0.89-1.30) and mean flow velocity, 15.44 ± 2.63 cm/s (range: 12.80-18.10). All the measurements in males were significantly higher than those in females (P < 0.001). Conclusion: The normal values of PV parameters have been established in adult subjects in Zaria. These values will serve as a reference to detect abnormalities of dimensions and flow velocities in the PV, thus enabling quantitative evaluation of patients with suspected PV disease. |
