Background Liposuction is one of the most commonly performed aesthetic procedures. Toxic shock syndrome(TSS) is a rare, life-threatening complication. The incidence rate of TSS is very low in the plastic surgery field, especially after liposuction and fat transfer. Case presentation A 23-year-old female patient was transferred to our emergency department from an aesthetic clinic with sepsis shock features after received liposuction and fat transfer. The patient underwent TSS, disseminated intravascular coagulation(DIC), multiple organ dysfunction syndrome (MODS), symmetrical peripheral gangrene (SPG), and necrotizing soft tissue infection of the buttocks in the next 10 days. Authors used a series of debridement and reconstructive surgery including vacuum sealing drainage (VSD) treatment, artificial dermis grafts,split-thickness skin grafts, amputation surgeries when her vital signs were stable. The patient experienced desquamation of the hand on the 26th day. The skin grafts survived and the function of both fingers and toes recovered. She was discharged 2 months after admission and was in good health. Conclusion TSS is extremely rare in the field of liposuction and autologous fat transfer. The mortality rate of TSS is very high. Early diagnosis and operative treatment, as well as correction of systemic abnormalities, are the important keys to save a patient's life.

Background Tissue expansion (TE) has attracted significant attention from researchers over the past decade. However, there are currently no bibliometric analyses in this field. We aimed to quantitatively and visually analyze the literature to explore the hotspots and frontiers in TE research. Methods We extracted all the documents on this topic published from the Web of Science Core Citation (WOSCC) database between 2012 and 2021. CiteSpace (version 5.8 R3) and VOSviewer (version 1.6.18) were used to perform the visualization analysis. Results A total of 1,085 documents were included in the analysis. The publication trend fluctuated over time. The United States led the research, and Harvard University was the most productive institution. Plastic and Reconstructive Surgery published the largest number of documents and had the most citations. Kim JYS was the most prolific and most cited author. The high-frequency keywords were “complications”, “breast reconstruction”, “outcomes”, “tissue expander”, “mastectomy”, and “acellular dermal matrix” (ADM). “Surgical site infection”, “tissue expander/implant”, “bilateral prophylactic mastectomy”, and “activated controlled expansion” were the keywords with the strongest citation bursts until 2021. Conclusions This study provided a complete analysis of the research on TE. The effect of ADM on the complication rates after breast reconstruction is the current hotspot of TE research in surgery. Patient-activated controlled expansion might be a promising future research direction for TE.
