Banding is a medical procedure which uses elastic bands for constriction. Banding may be used to tie off blood vessels in order to stop bleeding, as in the treatment of bleeding esophageal varices. [1] The band restricts blood flow to the ligated tissue, so that it eventually dies and sloughs away from the supporting tissue.
This is typically in addition to endoscopic banding or sclerotherapy for the varices. [21] If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. [21] If bleeding continues then balloon tamponade with a Sengstaken-Blakemore tube or Minnesota tube may be used in an attempt to mechanically compress ...
Esophageal varices seven days after banding, showing ulceration at the site of banding. The upper two thirds of the esophagus are drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava.
[16] [30] It is the only medication that has been shown to reduce mortality in acute variceal bleeding. [30] This is in addition to endoscopic banding or sclerotherapy for the varices. [13] If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. [13]
The National Institute for Health and Clinical Excellence (NICE) produced clinical guidelines in July 2013 recommending that all people with symptomatic varicose veins (C2S) and worse should be referred to a vascular service for treatment. [33] Conservative treatments such as support stockings should not be used unless treatment was not possible.
Anorectal varices are collateral submucosal blood vessels dilated by backflow in the veins of the rectum. [1] 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 .
A portacaval anastomosis or portocaval anastomosis is a specific type of circulatory anastomosis that occurs between the veins of the portal circulation and the vena cava, thus forming one of the principal types of portasystemic anastomosis or portosystemic anastomosis, as it connects the portal circulation to the systemic circulation, providing an alternative pathway for the blood.
Sclerotherapy, a minimally invasive procedure that uses chemicals to shrink varicose veins through endoscopy, was later enhanced with the introduction of variceal band ligation. Technological advancements also led to pharmacological therapies and interventional radiologic procedures like transjugular intrahepatic portosystemic shunt (TIPS ...
