Abstract:

Background: Liver cirrhosis is a life threatening condition, its consequences ranging from gross financial loss to death. Grayscale ultrasound has been used since long for the diagnosis of liver cirrhosis. Gray scale sonography along with color Doppler is the first-line modality used for evaluating the mean velocity of portal vein in Liver Cirrhosis. Chronic liver parenchymal diseases (CLPD) and liver cirrhosis cause decrease in the flow velocity of portal vein. Doppler ultrasound (US) can determine portal vein (PV) velocity in liver cirrhosis. The mean velocity of portal vein provides a disti

Abstract:

BACKGROUND: Liver cirrhosis is an end-stage liver disease characterized by pathologic fibrosis and regenerative nodules with resultant liver dysfunction. The diagnostic hallmark of portal hypertension is slow flow velocities in addition to the increased caliber of the mean portal vein. That is, the diagnosis of portal hypertension requires the measurement of mean portal velocity and portal diameter, and the correlation between cirrhosis and mean portal velocity and port diameter is the correlation between liver cirrhosis and its complications.OBJECTIVE: To analyze the correlation between porta

ABSTRACT: Pulsed Doppler ultrasound was used to evaluate portal blood flow, portal velocity and portal congestion index in 24 healthy sheep divided into groups (lambs, yearlings and ewes), according to age. Measurements were performed at the 11th right intercostal space using ideal insonation angle and uniform insonation method. Mean values obtained in each group were compared with one-way ANOVA, followed by Tukey post-hoc test. Portal velocity and portal blood flow were statistically similar between the groups (P>0.05).

In addition, gossypol is primarily cleared and excreted from the animal via liver glucuronidation, which is a primary pathway for steroid clearance in ruminants.

Portal vein thrombosis (PVT) is an important complication that is associated with cirrhotic portal hypertension.

This paper investigated the hemodynamics in the portal vein model, both with and without thrombosis, as well as the effect of obstructions on the hemodynamics of the portal vein system using the computational fluid dynamics (CFD) method.
