“…It is well recognized that the portal vein in humans is without venous valves in its larger channels (Douglass et al , Gabella , Burroughs ). There appears to be no published information on this matter in the dog although personal intraoperative observations suggest that the portal venous system is also valveless in this species (personal observation).…”

Morphology of congenital portosystemic shunts involving the right gastric vein in dogs

The morphology of each shunt type described appeared to be a result of an abnormal communication between the left gastric vein and the caudal vena cava, the presence or absence of an abnormal communication between the splenic, left gastric and portal veins and the subsequent development of preferential blood flow through essentially normal portal vessels within the portal venous system. The abnormal communication (shunt) was through the left gastric vein and not the right gastric vein, as might have been expected. This information may help with surgical planning in cases undergoing shunt closure surgery.

“…As the vast majority of the liver's blood supply originates from the portal vein 19 and for safety reasons, we restricted hepatic inflow analysis to blood collections from the portal vein. Postoperative blood samples were collected from a central line.…”

“…Increased blood flow in the portal vein, as a result of splanchnic vasodilatation, contributes to portal pressure as well [1,2]. Splanchnic vasodilatation is a consequence of the abundant production of vasoactive, particularly vasodilating, substances (such as Nitric Oxide) in mesenterial lymph nodes, as a result of the ongoing low-intensity chronic inflammation initiated and promoted by intestinal bacterial translocation.…”

Non-invasive diagnosis of portal hypertension in cirrhosis using ultrasound based elastography

et al. 2017

Liver stiffness measurement (LSM) by ultrasound-based elastography may be used to non-invasively discriminate between the stages of liver fibrosis, rule out cirrhosis and follow its evolution, including the prediction of the presence of oesophageal varices. The same is possible in order to diagnose clinically significant portal hypertension, referring primarilyto transient elastography and LSM values ≥20-25 kPa. The same approach may be used to reliably rule out the presence ofoesophageal varices (LSM <20 kPa + platelets >150x109/L). These recommendations refer primarily to patients with viral aetiology of chronic liver disease (hepatitis C), while additional studies are required for other aetiologies. While spleen stiffness measurement (SSM) also poses a logical choice in this indication, controversial results have nevertheless been published on this issue. It should be emphasized, however, that more recent data indicate that this parameter should be included in the diagnostic algorithm for portal hypertension, if not as the sole then as a part of a sequential algorithm, combined with LSM. Until now, transient elastography has been most extensively studied and founded on scientific evidence, although the results of other ultrasound-based elastography techniques demonstrate the same trend for the non-invasive assessment of portal hypertension.
