Hepatic vein

The hepatic veins (called know-hepatic in the old French nomenclature) are Veine S draining the Sang deoxygenized Foie and the blood deoxygenized and cleaned (by the liver) of the Estomac, of the Pancréas, the Small intestine and the Côlon towards the lower Vena cava.

They must be distinguished from the Portal vein, the latter taking along the blood of the digestive tract towards the liver.

They are born from the hepatic parenchyma, more exactly starting from the veins centrolobulaires of the liver. They are thrown in the lower vena cava.

They can be divided into two groups, superior and inferior. The veins of the higher group are born typically from the posterior wall of the liver, are three and drain the lobes square and left. The veins of the lower group come from the lobes right and caudé, are of variable number, and are typically smaller. None of them has valve.

Exploration

They are particularly well visualized at the time of a hepatic echography.

Pathology

They can be dilated in the event of increase in the pressure in the right cavities of the Cœur, in particular at the time of a Cardiac failure or a pulmonary arterial Hypertension.

The occlusion of these veins is responsible for the Syndrome of Budd-Chiari.
