Typically this occurs due to portal hypertension which shunts venous blood from the portal system through the portosystemic anastomosis present at this site into the systemic venous system. [ 2 ] [ 3 ] This can also occur in the esophagus , causing esophageal varices , and at the level of the umbilicus , causing caput medusae . [ 4 ]
It is also used for the treatment of pancreatic or duodenal trauma, or chronic pancreatitis. [2] Due to the shared blood supply of organs in the proximal gastrointestinal system, surgical removal of the head of the pancreas also necessitates removal of the duodenum , proximal jejunum , gallbladder , and, occasionally, part of the stomach .
The portal vein is not a true vein, because it conducts blood to capillary beds in the liver and not directly to the heart. It is a major component of the hepatic portal system , one of three portal venous systems in the human body; the others being the hypophyseal and renal portal systems.
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
Stasis dermatitis is diagnosed clinically by assessing the appearance of red plaques on the lower legs and the inner side of the ankle. Stasis dermatitis can resemble a number of other conditions, such as cellulitis and contact dermatitis, and at times needs the use of a duplex ultrasound to confirm the diagnosis or if clinical diagnosis alone is not sufficient.
Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3]
