Lipotransferencia

BACKGROUND: Lipofilling is a treatment modality to restore tissue volume, but it may also rejuvenate the aging skin. Platelet-rich plasma has been reported to augment the efficacy of lipofilling, both on graft take and rejuvenation, by altering the adipose-derived stem cells. The authors hypothesized that addition of platelet-rich plasma would increase the rejuvenating effect and shorten recovery time. METHODS: The study conducted was a single-center, double-blind, placebo-controlled, randomized trial (2012 to 2015)...

BACKGROUND: Despite rapid growth, gluteal fat transplantation is an operation in search of science and a teachable technique. Long operating times, tedious syringe transfers, inability to shape the recipient site, and the risk of fat embolism all headline as impediments to clinical adoption of the procedure. Expansion vibration lipofilling is a syringe-free surgical strategy that is a logical extension of Separation, Aspiration, and Fat Equalization (SAFELipo). In expansion vibration lipofilling, there is simultaneous disruption of recipient-site connective tissue, internal expansion using exploded-tip cannulas, and backfilling of these spaces with roller pump-propelled fat...

Background: Fat grafting has been gaining attention in tissue augmentation over the past decade, not only for lipofilling, but also for its observed regenerative properties and overall skin texture improvement. Objectives: The aim of this study was to analyze the effect of nanofat grafting on scars, wrinkles, and skin discolorations in our clinic. Methods: Nanofat was prepared by a standard emulsification and filtration protocol. The resulting liquid was injected intradermally or directly into the scar tissue...

Autologous fat grafting (AFG) or lipofilling is nowadays a popular technique for breast reconstruction after breast cancer surgery. There is debate regarding the oncological safety and risks of this procedure in breast cancer patients. A systematic review of the literature published between January first 1995 and October first 2016 was conducted regarding the efficacy, safety and complications of this technique in breast cancer patients after their cancer treatment. The databases PubMed, Science Direct and Thomson Reuters Web of Science were used to search for qualified articles...

INTRODUCTION: The 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 CASE: We performed a literature review of this technique, highlighting the crucial role of lipofilling in breast cancer reconstruction...

Lipofilling or lipografting is a novel and promising treatment method for reduction or prevention of dermal scars after injury. Ample anecdotal evidence from case reports supports the scar-reducing properties of adipose tissue grafts. However, only a few properly controlled and designed clinical trials have been conducted thus far on this topic. Also, the underlying mechanism by which lipofilling improves scar aspect and reduces neuropathic scar pain remains largely undiscovered. Adipose-derived stromal or stem cells (ADSC) are often described to be responsible for this therapeutic effect of lipofilling...

BACKGROUND: The aim of breast conserving surgery (BCS) is to excise the cancer with clear margins whilst at the same time leaving a good or excellent cosmetic result. A significant percentage of women, who have large cancers or have limited breast volumes, achieve poor cosmetic outcomes. BCS with immediate volume replacement using lipofilling or autologous fat transfer is a new technique. The aim of this study was to evaluate the cosmetic outcomes of a pilot study of patients having BCS and immediate lipofilling performed in The Edinburgh Breast Unit...

Autologous fat transfer, or lipofilling, is a common technique used for soft tissue reconstruction. It has been used for many years, but the technique is associated with a significant graft resorption rate (20% to 80%). To improve the fat graft survival rate, several methods have been tested, and one has appeared more promising: cell-assisted lipotransfer (CAL). In the CAL method, fat is enriched with adipose-derived stromal cells (ASC), contained in the stromal vascular fraction (SVF) obtained after enzymatic digestion of fat or after cell culture to improve the fat survival rate...

BACKGROUND: For years, the safety and effectiveness of autologous fat grafting (AFG) for breast reconstruction have been in question, with particular concern over fat necrosis, calcifications, cyst formation, and interfering with the detection of breast cancer. However, increasing evidence suggests that the complication rates and clinical results are generally acceptable to both clinicians and patients. The emerging challenge is the numerous AFG techniques and systems, where there are limited knowledge and data...

BACKGROUND: Lipofilling is an increasingly popular technique for breast reconstruction following both mastectomy and breast-conserving surgery (BCS). However, concerns remain over its oncological safety and its effect on cancer recurrence. MATERIALS AND METHODS: A systematic literature review and meta-analysis was carried out. Patients who had undergone mastectomy or BCS were investigated separately in order to find out whether the addition of lipofilling had a significant effect on locoregional recurrence rate...

During adolescence, psychological and physical changes occur and breast takes a major place in the young woman body image. Except rare malign tumors, breast pathologies at this age are mainly benign or malformative. Malformative issues are revealed during breast growth, as isolated asymmetry or associated to other regional anomalies, with abnormal shape or volume of the breast, or even supernumerary breast. Therapeutic solutions will not differ from the ones used for adults. Breast lipofilling, recently admitted by plastic surgery community is an interesting tool that can be used on young women...

The aging hand is characterized by skin changes and soft-tissue deflation, which leads to rhytides, dermal atrophy, and distinct anatomical structures. Soft-tissue deflation and prominent hand anatomy can be corrected with volume augmentation using dermal fillers or lipofilling. Fat transfer volumizes the hand with prolonged durability and efficacy, autologous tissue replacement, and possible dermal regeneration. The senior author's (R.J.R.) technique for hand rejuvenation is described, which uses minimal access and blunt dissection to effectively augment the soft-tissue compartments of the hand...

BACKGROUND: Current brachioplasty techniques include excisional surgery alone or in combination with liposuction. These techniques are associated with poor outcomes, such as residual contour deformities and unfavorable scarring. OBJECTIVES: The authors proposed a new classification system and treatment algorithm for brachial ptosis and described their experience with power-assisted liposuction and lipofilling to treat brachial ptosis without excisional surgery. METHODS: Ninety-five patients with grades 1, 2, or 3 brachial ptosis who underwent brachioplasty were evaluated in a prospective study...

BACKGROUND: Autologous fat grafting is an increasingly popular procedure used for facial rejuvenation and body contouring. The purpose of this article is to perform an evidence-based review to determine fact from fiction for the hot topics in autologous fat grafting. METHODS: A comprehensive literature search was performed. The following key words were then searched: "fat grafting," "autologous fat grafting," "autologous fat transfer," "lipotransfer," "liposculping," and "lipofilling...

The following case series describes the treatment of neuropathic pain in post-surgical scars, using adipocytes and adipose-derived stem/progenitor cells (ASCs). Two cases are described in which patients underwent lipofilling to treat painful scars after cosmetic surgery. The primary indication for lipofilling was pain reduction and not improved cosmesis. Numeric rating scale (NRS) values were reported before the intervention and at regular intervals after the lipofilling. We found a notable long-lasting reduction in the NRS values after the "modified" lipofilling treatment...

Usually, complicated reconstructions demand complex procedures. However, we report an unpublished situation where lipofilling was the only effective procedure for breast reconstruction, once 4 previous procedures, including 2 microvascular free flaps, had failed. The reported case describes a woman without subcutaneous tissue in the left breast topography, with radiation sequelae resulting in a fibrotic, hyperchromic, unexpandable skin that was tethered to her costal bone and pleura. The 4 previous attempts of breast reconstruction resulted in unavailable nearby recipient vessels, and this situation appointed breast lipofilling as the most feasible procedure...

We propose a safe, simple, and novel method to harvest fat using a standard liposuction cannula and a Redivac or alternative closed-suction drain. The authors have used this technique for both 'dry' and 'wet' liposuction. This technique is both easy to perform and cost-effective whilst providing both a silent and relatively atraumatic fat harvest. The lower negative pressure compared with traditional harvesting systems likely preserves fat integrity for lipofilling. This method maximises resources already held within a hospital environment...
