BACKGROUND: Autologous fat grafting (AFG) has been established over the past two decades as an additive technique during and after breast reconstruction. Complete reconstruction of the breast mound with AFG alone represents an exceptional technique that has been published mostly in case reports or in studies with limited cases. The purpose of this study is to investigate the influence of three different techniques for breast reconstruction on the recovery of skin sensitivity at the reconstructed breast. METHODS: The study included 30 patients after mastectomy following breast cancer. Three groups were examined: A) breast reconstruction by autologous fat grafting (AFG), B) breast reconstruction by deep inferior epigastric artery perforator flap (DIEP) and C) breast reconstruction by expander/implant (TE). Biometric data were compared; sensitivity tests were performed using Semmes-Weinstein monofilaments. The non-operated, healthy contralateral breasts of the patients were used as a reference. RESULTS: While the traditional reconstruction techniques by microsurgical anastomosed perforator flap or expander/implant showed a strongly decreased or completely missing sensitivity of the skin, the tests after reconstruction by AFG represented high values of sensory recovery, which came close to the reference group of non-operated breasts. CONCLUSION: To our knowledge, this is the first study to compare skin sensitivity after AFG-based reconstruction to established techniques for breast reconstruction. We could demonstrate in a limited group of patients, that breast reconstruction by autologous fat grafting can achieve higher values of skin sensitivity compared to traditional techniques.

Abstract 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.

Abstract Background Coronary artery perforation (CAP), although rare, can often be a life-threatening complication of percutaneous coronary intervention. Looped wire tip or buckling of wire is conventionally considered safer due to reduced risk of migration into smaller branches and false lumen. Occasionally, buckling can indicate the entry of tip into dissection plane, or the advancement of looped wire can cause small vessel injury leading to perforation. Distal coronary perforation can be life threatening and coil, foam, and thrombin injection are some of the material widely used for sealing it. Case summary We hereby report three different cases illustrating the vessel injury that the looped wire can cause in the distal vasculature related to various mechanisms like high elastic recoil tension, dissection by the non-leading wire tip, or hard wire lacerating the fragile small branches. All these mechanisms lead to distal coronary perforation leading to cardiac tamponade. Each case also illustrate the novel technique of autologous fat globule embolization for the management of distal CAP. Discussion Distal coronary perforation is often due to guidewire-related vessel injury and is more common with hydrophilic wires. Looped wire tip can sometime indicate vessel injury and its advancement further down the coronary artery may result in serious vessel injury and perforation. Management of distal coronary perforation is challenging, and here we demonstrate the steps of using the readily available autologous fat globules by selectively injecting them into the small coronary artery to control the leak.

Abstract Background A standardized technique for facial fat grafting, Injectable Tissue Replacement and Regeneration (ITR 2), was developed to address both anatomic volume losses in superficial and deep fat compartments as well as skin aging, incorporating newer regenerative approaches. Objectives The authors sought to track the short and long terms effects of a new standardized technique for facial fat grafting in the midfacial zone across a 19-month time period. Methods Twenty-nine female were analyzed for mid-facial volume changes after autologous fat transfer with ITR 2. Across 19 months, volumes were evaluated using the Vectra XT 3D Imaging System to calculate differences between a predefined, 3-dimensional mid-facial zone measured preoperatively and serially after fat grafting with novel approach using varying fat parcel sizes. Results Patient data was analyzed collectively as well as separately by age (< and > 55 years). Collective analysis revealed a trend of initial volume loss within the first 1-7 months followed by an increase within the 8–19-month range, averaging 56.6% postoperative gain and ending at an average of 52.3% gain in volume by 14-19 months. A similar trend was observed for patients <55 years of age, but to a greater extent, with a 54.1% average postoperative gain and final average of 75.2%. Conversely, patients above 55 years of age revealed a linear decay beginning at 60.6% and steadily declining to 29.5%. Multiple regression analysis revealed no statistically significant influence of weight change during the study duration. Conclusions Preliminary evidence shows a dynamic change in facial volume, with an initial decrease in facial volume followed by a rebound effect that demonstrated improvement of facial volume regardless of patient weight change or amount of fat injected 19 months after treatment. Volume improvement occurred to a greater extent in patients under 55 years old, whereas in patients older than 55 volume gradually decreased. To our knowledge, this study represents the first time that progressive improvement in facial volume has been shown 19 months after treatment with a new standardized technique of fat grafting.
