On the History of Hepatic Vein Catheterization. [PDF]
Liver IntABSTRACT Hepatic vein catheterization (HVC) in man was first performed 80 years ago in the wake of right‐sided heart catheterization. Several new methods, recognitions and concepts followed, especially the indirect Fick‐method for determination of splanchnic blood flow. Five years passed before pressure measurements were performed and routine HVCs were
