Transfemoral balloon catheterization for hepatic wedge pressure measurements
Radiology
|June 1, 1980
Abstract:
A method for obtaining wedged hepatic venous pressures with a balloon catheter is described. The catheter is introduced percutaneously into the femoral vein. This method is easier to perform than the venous cutdown technique used with Swan-Ganz catheters, and the results are more representative of average parenchymal pressure than standard wedged catheter measurements are.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
