Abstract
Objectives:To assess whether the extension of the flushing interval will increase risks of complications associated with totally implantable venous access port (TIVAP) in the off-treatment period.Methods:A retrospective single-center observational study was performed.Patients with a TIVAP in the off-treatment period that underwent regular flushing in our clinic were included.Data concerning pa-tients and their TIVAPs were recorded.Patient baseline characteristics and TIVAP-related complications were analyzed.Continuous variables were analyzed by ANOVA or the Kruskal-Wallis H test.To compare the occurrence of TIVAP-related complications,the chi-square test was used;if needed,Fisher's exact test was used.Results:Totally 607 patients were reviewed,and 563 patients were finally included.Thirteen compli-cations were recorded,including 11 cases of catheter occlusion (1.95％),one case of port cannula rotation(0.18％),and one case of catheter tip malposition (0.18％).No device-related infection or venous throm-bosis was recorded.Among these patients,the average flushing interval was 35.27 ± 13.09 days.Patients were divided into three groups according to the flushing interval:every 28 days or less (Group 1,n =133);every 29-44 days (Group 2,n =350);and every 45 days or more (Group 3,n =80).No significant difference in catheter-related complications was found among the three groups (P ＞ 0.05).Conclusions:In the TIVAP off-treatment period,patients without any history of TIVAP-related compli-cations during approximately one year can attempt to prolong the flushing interval to more than 4 weeks;we further suggest that 5-6 weeks may be an appropriate option for these patients.关键词
