863 Peri-Implant Fluid Collection in Breast Reconstruction and Aesthetic Surgery

Abstract

Abstract Introduction Peri-implant fluid more than 6 months from surgery is a known complication of breast surgery.Differential diagnosis includes infection, inflammation,implant rupture and haematoma.Other than infection raised no concern until the identification of Breast Implant Associated Anaplastic Large Cell Lymphoma(BIA-ALCL). Method Retrospective electronic data collection for women 18 years or older who met the following inclusion criteria:(a)oncoplastic and/or cosmetic reconstructive surgery with placement of implant(b)peri-implant fluid collection after 6-36 months. Results In total,17 women with implants with a mean age of 56 years were included in the study.The mean time between reconstructive surgery and the peri-implant fluid collection was 23 months.The median peri-implant fluid collection size was 143 ml.14 of the 17 peri-implant fluid collections were benign.12 of 14 had polyurethane-coated textured implants.4 of the 17 were BIA-ALCL. Conclusions The current literature suggests that late peri-implant seromas arise from friction as the implant moves within the cavity and that this friction is increased with textured rather than smooth implants.In our unit 12/14 of the benign collections appeared in reconstructions with polyurethane implants.Furthermore,BIA-ALCL should always be considered in this situation and aspirate should be sent for cytology.Is this change in polyurethane implants a new entity?
