Definition / general
- Dilated tortuous vessels, usually submucosal, that develop due to portal hypertension (prolonged or severe), which induces formation of collaterals between portal and caval systems (Wikipedia: Esophageal Varices [Accessed 15 February 2019], eMedicine: Portal Hypertension [Accessed 15 February 2019], eMedicine: Esophageal Varices Imaging [Accessed 15 February 2019], Mayo Clinic: Esophageal Varices [Accessed 15 February 2019])
- Collaterals in lower esophagus divert flow from portal vein, through coronary veins of stomach, into esophageal veins, then azygous veins, then into vena cava
Clinical features
- Present in 90% of cirrhotic patients, usually due to alcoholism; acute alcohol intake may cause death, often outside the hospital (Arch Pathol Lab Med 2002;126:1197)
- May rupture and cause massive hemorrhage (cause of death in 50% with advanced cirrhosis)
- 40% die in first episode of bleeding varices; rebleeding occurs in 50% of survivors within 1 year with 40% mortality
- Blood stains at death scene and unusual body positions of deceased are clues to fatal esophageal variceal hemorrhage
- #2 cause of bleeding varices worldwide is hepatic schistosomiasis
- "Downhill" varices occur in upper esophagus from other causes (Rev Esp Enferm Dig 2006;98:359)
Treatment
- Repeated sclerotherapy (injection of thrombotic agents, Ann Surg 2006;244:764), banding / ligation (Arq Gastroenterol 2005;42:72), balloon tamponade, beta blockers or octreotide to reduce portal blood flow, TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure, liver transplant
Gross description
