Abstract

A growing number of studies have explored endoscopic ultrasound (EUS)-guided vascular catheterization. Potential clinical applications of EUS-guided portal venous access include angiography, measurement of the portosystemic pressure gradient, EUS-guided transhepatic intrahepatic portosystemic shunt creation and portal vein sampling for the evaluation in gastrointestinal cancer. The following article reviews the different devices and techniques employed in these applications.

Keywords: Hepatic venous portal gradient; Portal pressure gradient; Portal vein sampling; Transhepatic intrahepatic portosystemic shunt; Endosonography.
