Portal Venous Pressure Variation during Hepatectomy: A Prospective Study [PDF]
Acta Médica Portuguesa, 2019 Introduction: Excessive portal venous pressure in the liver remnant is an independent factor in the occurrence of posthepatectomy liver failure and small-for-size syndrome. The baseline portal pressure prior to hepatectomy was not considered previously.

Stratified analysis of the correlation between wedged hepatic venous pressure and portal venous pressure in patients with portal hypertension [PDF]
Scientific ReportsTo evaluate the differences in the agreement between wedged hepatic venous pressure (WHVP) and portal venous pressure (PVP) at different hepatic venous pressure gradient (HVPG) levels to identify specific HVPG thresholds where WHVP can reliably estimate ...

Feasibility and safety of ultrasound-guided percutaneous transhepatic measurement of portal venous pressure. [PDF]
PLoS ONEBackground and objectiveThe measurement of portal venous pressure (PVP) has been extensively studied, primarily through indirect methods. However, the potential of ultrasound-guided percutaneous transhepatic PVP measurement as a direct method has been ...

Short-term effects of propranolol on portal venous pressure [PDF]
Hepatology, 1986 The present study was designed to investigate the effect of propranolol on portal pressure of patients with alcoholic cirrhosis and portal hypertension and to correlate these effects with clinical and laboratory parameters.

Gastroenterology, 1970 Combined hepatic and umbilicoportal catheterization was performed in 43 compensated cirrhotic patients. The umbilicoportal catheter was positioned in the portal vein (41 patients) or the left branch of the portal vein (2 patients). Wedged hepatic venous pressure was equal to free portal venous pressure in 17 patients.

Successful Treatment for Hepatic Encephalopathy Aggravated by Portal Vein Thrombosis with Balloon-Occluded Retrograde Transvenous Obliteration [PDF]
Case Reports in Gastroenterology, 2011 This report presents the case of a 78-year-old female with hepatic encephalopathy due to an inferior mesenteric venous-inferior vena cava shunt. She developed hepatocellular carcinoma affected by hepatitis C virus-related cirrhosis and underwent ...

Hepatic venous pressure gradient: Inaccurately estimates portal venous pressure gradient in alcoholic cirrhosis and portal hypertension. [PDF]
World J Gastrointest Surg, 2023 BACKGROUND Portal hypertension (PHT) in patients with alcoholic cirrhosis causes a range of clinical symptoms, including gastroesophageal varices and ascites. The hepatic venous pressure gradient (HVPG), which is easier to measure, has replaced the portal venous pressure gradient (PPG) as the gold standard for diagnosing PHT in clinical ...

Development of a Direct Non-Puncture Device for Measuring Portal Venous Pressure during Liver Transplantation—A Swine Model [PDF]
Biosensors, 2023 Portal hypertension-related complications pose a significant risk for liver failure post-transplantation. Thus, accurate monitoring of intraoperative portal venous pressure (PVP) is crucial.

Effect of Portal Venous Blood Flow Diversion on Portal Pressure [PDF]
Journal of Clinical Investigation, 1980 To anticipate the hepatic vascular response to portacaval anastomosis, we studied portal pressure during diversion of portal blood through a temporary extracorporeal umbilical vein to saphenous vein shunt. The relationship of portal pressure to shunted flow was approximately linear.

Pathophysiological role of prostanoids in coagulation of the portal venous system in liver cirrhosis. [PDF]
PLoS ONE, 2019 BACKGROUND:Prostanoids are important regulators of platelet aggregation and thrombotic arterial diseases. Their involvement in the development of portal vein thrombosis, frequent in decompensated liver cirrhosis, is still not investigated.
