Glue injection is a procedure used for treating gastric varices, a condition marked by the dilation of submucosal veins that line the stomach. It is a serious problem with life-threatening consequences if not managed properly. Gastric varices are commonly found in patients with underlying health issues like portal hypertension, which is usually associated with cirrhosis.
Glue injection involves the administration of a liquid monomer, cyanoacrylate, into varix using endoscopic guidance. As the glue comes in contact with the patient's blood, it polymerizes and turns into a solid substance that clogs varix.
