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 leads to varices in the esophagus and stomach, which can bleed; B) a needle has been introduced (via the jugular vein) and is passing from the hepatic vein into the portal vein; c) the tract is dilated with a balloon; D) after placement of a stent, portal pressure is normalized and the coronary and umbilical veins no longer fill.
The use of the tube was originally described in 1950, [1] although similar approaches to bleeding varices were described by Westphal in 1930. [2] With the advent of modern endoscopic techniques which can rapidly and definitively control variceal bleeding, Sengstaken–Blakemore tubes are rarely used at present.
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.
In situations where portal pressures increase, such as with cirrhosis, there is dilation of veins in the anastomosis, leading to esophageal varices. [3] Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure. Splenectomy can cure the variceal bleeding due to splenic vein thrombosis.

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 varix (pl.: varices) is an abnormally dilated blood vessel with a tortuous course. Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. [1] Examples of varices include: [citation needed] Varicose veins, large tortuous veins usually found on legs; Sublingual varices
