Esophageal varices are abnormal blood vessels (veins) that develop in the esophagus. They have abnormally thin walls, and the blood pressure within them is very high. This combination makes esophageal varices very dangerous, because they can burst and cause life-threatening bleeding.
Esophageal variceal injection is a procedure to either prevent future bleeding or stop active bleeding. During the procedure, medicine is injected into or alongside esophageal varices. When injecting into the vein, the medicine causes blood clots to form, blocking the vein from bleeding. When injected alongside the vein, the swelling in the area compresses the vein, preventing it from bleeding.
The procedure is also known as sclerotherapy.
Esophageal varices can be life-threatening. Esophageal variceal injection is a procedure that can make them less likely to bleed. The procedure is also used to stop active bleeding from esophageal varices.
