ObjectiveTo systematically review the procedure, applications, and outcomes of autologous fat grafting, a promising technique with various clinical applications.Patients and methodsLiterature review of publications concerning autologous fat grafting.ResultsSince its introduction, lipofilling has become increasingly popular; however, its results are variable and unpredictable. Several modifications have been made to the procedures of fat harvesting, processing, and injecting. Surgical excision and low negative-pressure aspiration with large-bore cannulas minimize adipocyte damage during fat harvesting. The “wet” method of fat harvesting involves fluid injection at the donor site and facilitates lipoaspiration while minimizing pain and ecchymosis. For fat processing, centrifugation at a low speed is preferable to high-speed centrifugation, gravity separation or filtration. Fat injection at the recipient site should be performed using small-gauge cannulas in a fanning out pattern over multiple sessions, rather than a single session. Fat grafts exhibit not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue. Thus, the clinical applications of autologous fat grafting include correction of secondary contour defects after breast reconstruction, release of painful scar contractures, and treatment of burn scars and radiodermatitis. Lipofilling is also used in aesthetic surgery, such as facial and hand rejuvenation, augmentation rhinoplasty, and breast and gluteal augmentation. The complications of lipofilling are minimal and include bruising, swelling, pain, infection, necrosis, and calcification.ConclusionsLipofilling is a low-risk procedure that can be used to correct soft-tissue defects in the face, trunk, and extremities, with minimal discomfort for patients.
IntroductionThe use of autologous fat transplantation to correct volume and contour defects, scars, and asymmetry after breast cancer surgery has increased over the past 20 years. Many developments and refinements in this technique have taken place in recent years, and several studies of the safety of lipofilling in the breast have been published.Presentation of caseWe performed a literature review of this technique, highlighting the crucial role of lipofilling in breast cancer reconstruction.DiscussionThe efficacy of the fat graft transplantation depends on the experience and the technique used by the surgeon. The ASCs (adipose-derived stem cells) contained in the fat graft has proven to be crucial for breast reconstruction by mean the regeneration of tissue, through the chemotactic, paracrine, and immunomodulatory activities and their in situ differentiation.ConclusionThe role of lipofilling for breast reconstruction could be more significant with the application of the findings of experimental research on tissue engineering and ASCs.
Worldwide, hard-to-heal lower limb wounds are estimated to affect 1.5–3% of the adult population with a treatment-related annual cost of $10 billion. Thus, chronic skin ulcers of the lower limb are a matter of economic and public concern. Over the years, multiple medical and surgical approaches have been proposed but they are still inadequate, and no effective therapy yet exists. Regenerative medicine and stem cell-based therapies hold great promise for wound healing. Recently, many plastic surgeons have studied the potential clinical application of adipose-derived stem cells (ASCs), which are a readily available adult stem cell population that can undergo multilineage differentiation and secrete growth factors that can enhance wound-healing processes by promoting angiogenesis, and hence increase local blood supply. ASCs have been widely studied in vitro and in vivo in animal models. However, there are few randomized clinical trials on humans, and these are still ongoing or recruiting patients. Moreover, there is no consensus on a common isolation protocol that is clinically feasible and which would ensure reproducible results. The authors aim to provide readers with an overview of the biological properties of ASCs as well as their clinical application, to help better understanding of present and future strategies for the treatment of hard-to-heal wounds by means of stem cell-based therapies.
Abdominoplasty is one of the most popular body-contouring procedures. It is associated with a significant number of complications: the most common ones are seroma, hematoma, infection, wound-healing problems, and skin flap necrosis. From January 2012 to December 2014, 25 patients (18 women and 7 men) (mean age: 51 years) underwent abdominoplastic surgery at the Plastic Surgery Section, Department of Surgical Sciences, University of Parma, Italy. All patients reported a weight loss between 15 kg and 47 kg. All of the of 25 patients were included in the study; minor and major complications were seen in 17 (68%) and 8 (32%) patients, respectively. The percentage of complications in our patients was as follows: 9 patients with seroma (36%); 4 patients with wound dehiscence with delayed wound healing (16%); 3 cases with hematoma (12%); 2 patients with postoperative bleeding (8%); 1 patient (4%) with an umbilical necrosis; 1 patient (4%) with a deep vein thrombosis; 3 patients with infected seroma (12%); and 2 patients with wound infection (8%). There were no cases of postoperative mortality. The aim of this study is to analyze our complications in postbariatric abdominoplasty.
