 [vār´iks] (L.)
an enlarged, tortuous vein, artery, or lymphatic vessel.
aneurysmal varix a markedly dilated tortuous vessel; sometimes used to denote a form of arteriovenous aneurysm in which the blood flows directly into a neighboring vein without the intervention of a connecting sac.
arterial varix a racemose aneurysm or varicose artery.
esophageal varices varicosities of branches of the azygous vein which anastomose with tributaries of the portal vein in the lower esophagus; due to portal hypertension in cirrhosis of the liver.
lymph varix (varix lympha´ticus) a soft, lobulated swelling of a lymph node due to obstruction of lymphatic vessels.

1. A tortuous dilatation of a vein. See: varicose vein
2. Less commonly, dilatation of an artery or lymph vessel.

aneurysmal varix

A direct communication between an artery and a varicose vein without an intervening sac.

arterial varix

A varicosity or dilation of an artery.

chyle varix

A varix of a lymphatic vessel that conveys chyle.

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


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


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.

Gastro-esophageal varices Type-1 (GOV1) is extension of esophageal varices along the lesser curve of the stomach, gastro-esophageal varices Type-2 (GOV2) is continuation of EV to the gastric fundus along greater curvature of stomach, isolated gastric varices Type-1 (IGV1) are present in fundus of stomach and lastly isolated gastric varices Type-2 (IGV2), are also labeled ectopic varices, they can be present anywhere in the pylorus antrum, or corpus, of stomach.13 We used forward viewing video endoscope (Olympus Optical Corporation, Tokyo, Japan) for endoscopic varix obliteration.

In larger specimens with the mature arrangement of varices, long pauses of up to several months occur between bursts of fast growth from one varix to the next (Inaba, 1967; MacGinitie and MacGinitie, 1968; Spight and Fyons, 1974; Illert, 1981).
Although the excretory urogram may demonstrate external compression of the renal pelvis or proximal ureter by the varix, phlebography with or without epinephrine is the historic diagnostic modality of choice.

Esophageal varix form, color, red color signs, or presence of risky bleeding signs were also not significantly different between the two PHG forms.
After resuscitation, endoscopic examination revealed an actively bleeding point arising from a large-sized esophageal varix at 5 cm above the gastroesophageal junction (Figure 1).
No sex difference in presence of the oesophageal varix was detected.
However, because the mechanism of varix obliteration differs between EIS and EBL, it is not clear whether EBL also affects portal pressure and GVs development.
There were no clinical signs of a hematoma or cord varix during office visits.
