Hepatic venous pressure gradient (HVPG) measurement: Tips and pitfalls of hepatic venous catheterization

Many noninvasive methods have been developed to determine HVPG to reduce the burden on patients, such as elastography using various imaging methods, Doppler parameters, contrast-enhanced ultrasound findings, and serum-based markers. The pathophysiology of PBC needs further evaluation in a larger pat...

Description
Summary:Many noninvasive methods have been developed to determine HVPG to reduce the burden on patients, such as elastography using various imaging methods, Doppler parameters, contrast-enhanced ultrasound findings, and serum-based markers. The pathophysiology of PBC needs further evaluation in a larger patient population. Veno-venous communication is common, and the following findings strongly suggest IPH: narrower angles between large veins and their tributaries, smooth and wavy middle-sized to large branches (“weeping willow” appearance), homogeneous sinusoidal filling, and minimal to absent filling of the portal venous system (Figure ). [...]hepatic venous catheterization provides useful information for diagnosing IPH. [...]management and interpretation of clinical symptoms may not be well organized because pain is
