Anesthesiological and postinterventional management in percutaneous hepatic melphalan perfusion (chemosaturation)

Abstract

Percutaneous hepatic melphalan perfusion (PHMP) is alast-line treatment of inoperable primary or secondary liver tumors. Selective perfusion and saturation (chemosaturation) of the liver with the chemotherapeutic agent melphalan is performed via catheterization of the hepatic artery without affecting the rest of the body with its cytotoxic properties. Using an extracorporeal circulation and balloon occlusion of the inferior vena cava, the venous hepatic blood is filtered and returned using abypass procedure. During the procedure, considerable circulatory depression and coagulopathy are frequent. The purpose of this article is to review the anesthesiological and postprocedural management of patients undergoing PHMP with consideration of the pitfalls and special circumstances.
