879 The Review of Autologous Fat Grafting Utilizing Negative Pressure for Breast Augmentation

Abstract

Abstract Aim There may be a role for topical negative pressure in autologous fat grafting to breasts since it enhances angiogenesis during wound healing for open and closed wound. Here, we present a review of the literature on this topic. Method Medline and Embase were utilised, with searches ranging between 1960 – 2019. Terms (“Liposculpting” OR “Fat grafting” OR “Lipofilling” OR “Lipograft” OR “Fat transfer”) AND (“Negative Pressure” OR “Brava” OR “Kiwi”) AND (“Breast”) were merged as keywords. Inclusion criteria were females, autologous fat graft to breast with negative pressure prior to procedure. Studies were excluded if there was no primary endpoint or non-original article. Primary outcome measured was fat graft survival post breast augmentation with post-operative morbidity as a secondary outcome. Results Upon reviewing 219 articles, 2 met inclusion criteria. A total of 611 breasts were treated using negative pressure devices, with each cohort having different pre- and post-operative pressure settings. Khouri et al. cohort had higher graft survival (79%) compared to Del Vecchio et al. cohort (64%), however the latter had fewer complications compared to Khouri’s cohort e.g. fat necrosis, pneumothorax and infection. Conclusions There is still limited evidence regarding the use of topical negative pressure for fat grafting to the breasts. Autologus fat grafting to breasts without the use of negative pressure is shown to have graft survival of 60-70%. Given its potential benefits, more future studies are needed to fully understand the impact of this technique.
