Abstract Totally implantable venous accessports (TIVAP) is a kind of deep vein infusion device implanted subcutaneously. It mainly includes venous poraccess system and an injection port for puncture. Venous access ports are able to provide safe, convenient, beautiful as well as long-term portable vascular access for those patients suffering from long-term infusion of chemotherapy drugs or parenteral nutrition, also for patients who need chronic transfusion due to chronic diseases. It has the advantages of low risk of infection, convenience for patients, reduction of the number of puncture vessels, simple maintenance and long service life. With the continuous progress and development of TIVAP, this technology has been accepted and applied by many clinical workers in China. However, there have been controversies in several aspects including making decisions of the implantation method and its route of venous access ports, the dosing interval after venous access ports implantation and whether antibiotics are supposed to be applied prophylactically prior to venous access ports implantation. Besides, the application of venous access ports in paediatric patients has triggered some dispute as well. Therefore, this article interprets the Expert Consensus on Nutrition Therapy Pathway for Malignant Tumors in China, and proposes suggestions on the methods of port implantation, post-implantation use and perioperative
management, offering guidance for the application of venous access ports in clinical practice, contributing to making optimal choice in nutritional treatment pathways for patients with malignant tumors according to the latest consensus.
