Abstract Background Totally implantable central venous access ports (TICVAPs) have increasingly been used in pediatric patients because they provide reliable venous access. However, many complications associated with TICVAPs have been reported. Here, we aimed to analyze the risk factors of stuck fragment of TICVAPs during removal in children and recommend the appropriate periods of use or exchange. Methods We retrospectively reviewed the medical records of 121 patients, including 147 cases of TICVAP insertion, between January 2010 and July 2020. Results Among these, 98 cases in 72 patients involved of TICVAP removal, with 8 patients having had incomplete TICVAP removal resulting in a stuck fragment of the catheter in the central venous system (Group S). All Group S patients were male and had acute leukemia, and their TICVAPs were used for chemotherapy. Compared with the complete removal group (Group N), stuck fragment in Group S were significantly found in patients diagnosed with acute leukemia than those with other diagnoses (p
