To determine if 3D ultrasound measurements can accurately measure the pressure of blood flow across a stent that has been placed in a portal vein to reduce portal vein pressure known as Transjugular Intrahepatic Porto-Systemic shunts or TIPS.

The effect of portal hypertension on gastrointestinal motility, and how reversal or improvement in portal hypertension may alter gastrointestinal motility, remains unclear and further rese...
TIPS has been used for 20 years, as a means of reducing portal pressure in patients with cirrhosis and portal hypertension related complications. TIPS proved more effective than alternativ...
To evaluate the clinical benefits in the patients receiving Viatorr CX over a period of 12 months of structured Follow-up (before TIPS, at TIPS, 1 week after TIPS, at 6 weeks, 4 months, 6 ...
Portal pressure gradient (PPG) above 12 mmHg after transjugular intrahepatic portosystemic shunt (TIPS) increases the risk of portal hypertension complications. Currently, a PPG reduction
Patients with advanced chronic liver disease may develop hypertension of the portal vein, which is the main cause for most complications and deaths of patients with liver cirrhosis. Implan...
The transjugular intrahepatic portosystemic shunt (TIPS) is a percutaneous imaging-guided procedure that effectively reduces portal pressure by diverting blood from the portal to the systemic circulat...
Doppler ultrasound (DUS) is frequently performed as a screening and diagnostic modality to evaluate the transjugular intrahepatic portosystemic shunt (TIPS) for short- and intermediate-term complicati...
We read with great interest the article by Elkrief et al. reporting long-term outcomes of abdominal surgery in patients with idiopathic noncirrhotic portal hypertension (INCPH) In a subgroup analysis,...
Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established procedure used in the management of complications of portal hypertension. Although the most robust evidence supports the use ...
This meta-analysis was performed to investigate the correlation between von Willebrand factor (vWF) antigen and hepatic venous pressure gradient (HVPG) and to evaluate the diagnostic performance of vW...
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
