%X With the continued application of fat grafting in plastic surgery, many studies have focused on various factors to improve maintenance of the fat graft volume, such as platelet-rich plasma, adipose-derived stromal/stem cells, and the stromal vascular fraction (SVF). In addition, many review articles have investigated the functions of platelet-rich plasma and adipose-derived stromal/stem cells in fat grafting, although the usefulness of the SVF remains unclear. The aim of the present review was to determine whether SVF use could maintain a fat graft.<BR>A systematic review was conducted of the PubMed, Cochrane Central Register of Controlled Trials, and Embase databases of original articles published up to February 2018.<BR>Relevant articles were identified by screening the abstracts. A total of 58 full texts were initially identified. After exclusion, 17 articles, including 6 animal studies and 11 clinical studies, were included for analysis.<BR>Most studies found a significant and measurable long-term effect of SVF-enhanced fat grafting on breast augmentation and defects, wound healing, scaring, and facial aesthetic outcomes. Stromal vascular fraction use did not result in a higher instance of complications and, thus, can be considered a safe option for fat grafting.
