ESOPHAGEAL VARIX IN A PATIENT WITH CIRRHOSIS OF THE LIVER: Courtesy of John Roberts, MD

esophageal varix

A tortuous dilatation of an esophageal vein, esp. in the distal portion. It results from any condition that causes portal hypertension, typically cirrhosis of the liver. Müller's maneuver; illustration

Symptoms

If an esophageal varix bursts, massive hemorrhage occurs, and the patient may die within minutes.

Treatment

Medical treatment includes administration of a beta blocker, such as nadolol, with a nitrate, such as isosorbide, to lower portal pressures and decrease the likelihood of variceal bleeding. Invasive therapies include the injection of sclerosing agents or rubber banding of the dilated vein.

Patient care

Bleeding esophageal varices constitute a medical emergency, requiring immediate treatment to control hemorrhage and prevent hypovolemic shock. The patient’s vital signs, SaO₂, ABGs, electrolyte and fluid volume balance, and level of consciousness are closely monitored. Intravenous access must be established promptly and fluid resuscitation, followed by transfusion and the administration of plasma are critical to early stabilization of the patient. Medical therapies also include the use of vasoconstricting drugs, such as vasopression. Endoscopy is used to identify the site of the ruptured vessels which may then be treated with sclerotherapy, ligation, or banding.

Surgical procedures to prevent rebleeding include portocaval or mesocaval shunts, portosystemic anastomosis, splenorenal shunting or liver transplantation. All procedures are explained, sensation messages provided, and reassurance and emotional support offered.

lymphaticus varix

Dilatation of a lymphatic vessel.

turbinal varix

Permanent dilatation of veins of turbinate bodies.

varices

Varicosities. Swollen, twisted and distorted lengths of vessels, usually veins. Veins affected by varices are called VARICOSE VEINS and these are commonest in the legs. Oesophageal varices are the varicosities of the veins at the lower end of the OESOPHAGUS that occur when the portal vein drainage through the liver is impeded by CIRRHOSIS. They are liable to cause dangerous bleeding. The singular form of the word is varix.

Varices

A type of varicose vein that develops in veins in the linings of the esophagus and upper stomach when these veins fill with blood and swell due to an increase in blood pressure in the portal veins.Mentioned in: Bleeding Varices, Sclerotherapy for Esophageal Varices
