VENOUS DRAINAGE
The final common pathway of hepatic venous drainage is via the three hepatic veins which enter into the IVC at the dome of the liver.
Tributaries include the right hepatic vein, middle hepatic vein, and left hepatic vein.
The veins are formed by branches of the segmental and subsegmental veins of the liver, and are originally formed at the center of the liver lobule where the hepatic venous radicle is called the central vein.
It is called the central vein because the sinusoids formed by the terminal portal venous and arterial terminal branches, converge to this central point of the liver lobule before they finally drain out of the liver.
The venous drainage of the caudate lobe enters independently into the IVC at a point more caudal than the major hepatic veins.
The hepatic venous anatomy forms the boundaries of the lobes and segments of the liver.
| The hepatic veins originate from the sinusoids and convey blood from the liver to the vena cava. Hepatic veins tend to be open and solitary, allowing them to be distinguished from the branches of the portal vein, which are more or less collapsed and always accompanied by an artery and duct.
Applied biology
Caput Medusa is a clinical sign characterised by prominent periumbilical veins, reminiscent of the Greek mythological figure typified by snakes in her hair, staring eyes, fang-like teeth, and protruding tongue. She was one of three ugly sisters (The Gorgons) who were so hidious that whoever observed them was turned to stone. Medusa was beheaded by Perseus but even after her death she retained petrifying power, and was used as an insignia on shields to frighten the enemy. Budd-Chiari syndrome is an acute, chronic or subacute thrombotic or obstructive circulatory disorder of the hepatic venous system cause multiple factors including hypercoaguable states masses around the hepatic veins resulting in thrombosis of the hepatic veins sinusoids or IVC characterised by liver congestion divided into ivc origin hepatic venous origin sinusoidal origin pathogenesis disorder causes liver injury results in variable outcome resolution fibrosis acute or chronic liver failure structural disorder chronic congestion functional disorder variable depending on ability to develop collateral clinical presentation pain ascites diagnostic studies include MRI US, CT, angiography treatment is commonly by anticoagulation

Caput Medusa is a clinical sign characterised by prominent periumbilical veins, reminiscent of the Greek mythological figure typified by snakes in her hair, staring eyes, fang-like teeth, and protruding tongue. She was one of three ugly sisters (The Gorgons) who were so hidious that whoever observed them was turned to stone. Medusa was beheaded by Perseus but even after her death she retained petrifying power, and was used as an insignia on shields to frighten the enemy.
