As a type of central venous access device, the totally implantable venous access port (TIVAP) is widely used in patients requiring long-term or intermittent intravenous infusion, chemotherapy, nutritional support, and other treatments. It effectively reduces the need for repeated punctures and offers advantages such as safety and convenience. However, in primary healthcare institutions, there are still inconsistencies in procedures and non-standardized practices in the maintenance and complication management of TIVAP. To enhance the safety and standardization of TIVAP usage and to ensure treatment efficacy, the Colorectal and Anorectal Surgery Branch of the Henan Medical Doctor Association convened a multidisciplinary panel of experts to develop this expert consensus on grassroots technical specifications, integrating domestic and international evidence-based findings and clinical experience. The consensus covers the assessment, maintenance, management, and prevention of complications of TIVAP, and proposes 10 expert recommendations with an emphasis on operational feasibility and suitability for primary care. It aims to provide scientific, standardized, and practical guidance for frontline healthcare workers, reduce the risk of complications, and improve clinical quality and patient safety.
