Esophageal Variceal Injection
Esophageal varices are abnormal blood vessels that develop in the esophagus. They have abnormally thin walls and the blood pressure within them is very high. This combination makes esophageal varices dangerous, because they can burst and cause life-threatening bleeding.
Esophageal variceal injection is a procedure to either stop active bleeding or prevent future bleeding. During the procedure, medication is injected into or alongside esophageal varices. When injecting into the vein, the medication 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.
