Effectiveness of breast fixation to reduce migration of the tip of a totally implantable venous access port in women

Abstract

Purpose: To evaluate effectiveness of breast fixation to reduce migration of the catheter tip of a totally implantable venous access port (TIVP) in women. Materials and methods: TIVPs were placed in 129 women via the right axillary vein from July 2012 to December 2014, with a final study population of 118 patients (mean age, 55.3 +/- 13.8 years; range, 21-91 years). The patients were divided into two groups according to breast fixation during TIVP placement. A total of 56 patients received TIVP placement without breast fixation (Group 1); the remaining 62 received TIVP placement in the supine position after fixation of the ipsilateral breast on the abdominal wall in the sitting position (Group 2). Medical records were retrospectively reviewed for age, weight, height, body mass index, and underlying malignancy. We evaluated the difference in distance ratios between the port chamber and the catheter tip on supine chest and erect chest radiographs, respectively. Statistical analysis was performed using Student's t test. Results: Differences in all parameters between Group 1 and Group 2 were not statistically significant. Mean distance ratio between the port chamber and the catheter tip was 1.95 +/- 0.97 in Group 1 and 1.33 +/- 0.59 in Group 2. Differences in distance ratios between the port chamber and the catheter tip were statistically significant between Group 1 and Group 2 (p = 0.001). Conclusions: Breast fixation seems to be effective in reducing migration of the port chamber and catheter tip with position changes in female patients during TIVP placement.
