Comparison of complications after closure of totally implantable venous access devices with non-absorbable suture and n-butyl-2-cyanoacrylate (NBCA) skin adhesive: Propensity score matching analysis.

Abstract

This study aimed to compare the complication rates of non-absorbable suture (NAS) and n-butyl-2-cyanoacrylate (NBCA) skin adhesive for skin closure during totally implantable venous access devices (TIVADs) implantation. Between March 2020 and February 2021, 586 consecutive patients who underwent TIVAD implantation were retrospectively analyzed. Two groups of patients suture with NAS (n = 299) or NBCA (n = 287) were followed up for 18 months to compare the occurrence of infection, thrombosis, and non-thrombotic malfunction. A total of 364 cases were extracted using propensity score matching in a 1:1 ratio. Mean TIVADs maintenance days were analyzed using Kaplan-Meier survival analysis. Nineteen cases of complications occurred (0.294/1000 catheter-days) in the NAS group and 17 cases (0.210/1000 catheter-days) in the NBCA group. The difference in the complication rates between the two groups was not statistically significant (p = 0.725) after propensity score matching. Mean TIVADs maintenance days were 627.3 days in NAS group and 697.6 days in NBCA group. There was no statistically significant difference in the number of TIVADs maintenance days between the two groups (p = 0.081). In TIVADs implantation, skin closure using NBCA showed no difference in the occurrence of infectious complications compared with conventional non-absorbable skin suture.
