Hepatic vein obstruction (Budd-Chiari)

Budd-Chiari syndrome; Hepatic veno-occlusive disease

Hepatic vein obstruction is a blockage of the hepatic vein, which carries blood away from the liver.

Digestive system

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Digestive system organs

The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.

Blood clot formation

Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Blood clots

Blood clots (fibrin clots) are the clumps that result when blood coagulates.
