A case of noncardiogenic pulmonary edema by ethanolamine oleate

Endoscopic injection of sclerosing agents is a strategy for control of esophageal varix bleeding. Five percent solution of ethanolamine oleate(EO) has been used as sclerosing agent. It is well known that intravascular injection of oleic acid induces acute respiratory failure in animal models. However, EO-induced noncardiogenic pulmonary edema has not been reported in human. We report a case of noncardiogenic pulmonary edema developed after therapeutic trial of EO as sclerosing agent for esophageal varix.
