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.

varices

[L.] plural of varix.

Conclusion: The presence of an enlarged spleen is a valid predictor of the presence of oesophageal varices in patients suffering with liver cirrhosis.
It is therefore pertinent to have gastric endoscopy in patients with PVT as portal hypertensive gastropathy is more often present in the acute PVT, secondary to cancer or cirrhosis, whereas large esophageal varices are often present in patients with chronic PVT.
Conclusion: The PC/SD ratio is found to be the most reliable marker to prognosticate esophageal varices.
Gastroesophageal varices are present in almost half of patients with cirrhosis at the time of diagnosis6 with incidence of 7% per year.

About 54% patients were excluded on the basis of finding of varices on upper GI endoscopy and previous history of variceal bleeding.
We explore the factors that affect lamellar growth and how lamellae differ in form from varices, and attempt to answer these questions: Are lamellae associated with a growth hiatus?
also have reported no clinical significant splenic infarctions or gastric varices in any case after the Warshaw operation [10].
Several lines of approach for acute bleeding of varices have been described, such as local measures of hemostasis (stitches on bleeding sites, silver nitrate cauterization).
Avoid nitrates in patients with varices because these agents do not prevent first variceal hemorrhage and have been associated with higher mortality rates in patients older than 50.
