Pathology of varices
Cirrhosis
Causes impaired blood flow through the liver
This increases the pressure in the portal vein causing blood to be forced into near by smaller veins, (porto systemic shunt)

Start terlipressin
Endoscopic banding or sclerotherapy (destroys veins)
Minnesota tube or Sengstaken-Blakemore tube
