A retrospective observational study on maintenance and complications of totally implantable venous access ports in 563 patients: Prolonged versus short flushing intervals.

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 patients 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 complications 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 thrombosis 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 complications 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.

Project description:IntroductionThe insertion of an implantable central venous access is performed according to a variety of approaches which allow the access to the subclavian vein, yet the supraclavicular technique has been underused and never compared to the other methods. The aim of this study was to testify on the efficacy and safety of the subclavian puncture without ultrasound guidance « Yoffa » in comparison with the classical infraclavicular approach (ICA).Material and methodsThis is a retrospective study with prospective data collection on patients followed at the national oncology institute for cancer, in the period extending from May 1st 2017 to August 31st 2017. All patients had a totally implantable central venous access device inserted by the same surgeon AS for chemotherapy administration and demographic characteristics, as well as procedure details were examined. The primary outcomes were the intraoperative complications, while the secondary outcomes represented immediate postoperative and mid-term complications (at 15 months of follow up). Outcomes were compared between techniques by means of non parametric tests and the Fischer test.ResultsOur study included 135 patients with 70 patients undergoing the subclavian technique, while 65 were subject to the infraclavicular approach. Both groups had no statistically significant demographic characteristics. The number of vein puncture attempts exceeding once, the accidental artery puncture and operative time were more significant in the ICA group; (39,6 vs 17,6 p = 0,01) (9.2% vs 0; p = 0,01) and (27± 13 vs 23± 8min, p = 0.045) respectively. There was no statistically significant difference in the immediate and midterm complication rate between the two methods 1(1,4) vs 2 (3) p = 0.5.ConclusionIn case of unavailability of ultrasonographic guidance, the use of the supra-clavicular landmarks approach is linked to higher success rates and less arterial punctures, thereby proving to be a safe and reliable approach.
