Varix
An enlarged and convoluted vein, artery, or lymphatic vessel. Treatment of varices depends on where they are and whether they are causing problems. A varix in the esophagus can be caused by severe liver disease and can lead to bleeding. This form of varix can require treatment to prevent dangerous bleeding.
