Fat Grafting to the Breast for Aesthetic Indications: Techniques and Outcomes in 165 Consecutive Patients.

PURPOSE: Fat grafting to the breast for aesthetic indications has become increasingly popular. Herein, methods, aesthetic outcomes, and complications are reviewed in a retrospective case series. METHODS: Female patients (n=165) with an average age of 45 years (range: 17-78 years) who underwent fat grafting to breast were evaluated. Demographic parameters, the type of procedure, the amount of fat transferred, the site(s) of fat harvest, operative times, and the patient's postoperative recovery and outcomes were recorded. RESULTS: Of the 165 patients, 105 had breast augmentation with fat only. Of these 105 patients, 14(8%) had implant removal with and without capsulectomy, and 61(37%) had mastopexies. Composite augmentation was performed in the remaining 60 patients. The average amount of fat used was 208 cc (range: 10 to 945 cc) per breast. Forty-five patients (27%) underwent a second procedure. Of the 165 patients, 37(22%) had adverse events unrelated to the fat graft, including suture abscesses, scarring, and minor incision cite skin breakdown. Four patients (2.4%) had a complication related to fat grafting including 'lump' formation between the breast, abnormal mammograms, and the need for simple aspiration of a lipid cyst. CONCLUSIONS: Autologous fat grafting should be considered for both primary and secondary aesthetic breast surgery to enhance outcomes. Complications related to fat grafting are uncommon. Revisional and secondary surgeries may be needed to achieve the desired outcome. Power-assisted liposuction, with vibratory infiltration of the tumescent solution, auto-infusion of fat, and Expansion Vibration Lipofilling using a closed system has become our preferred technique. Fat grafting to breast can be considered for both primary and secondary aesthetic breast surgery Complications related to fat grafting are uncommon There does not appear to be an overall increase in complications of associated mastopexy and composite augmentation LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Hybrid Stromal Vascular Fraction (Hybrid-SVF): A New Paradigm in Mechanical Regenerative Cell Processing.

Enzymatic digestion of extracellular matrix (ECM) from lipoaspirate is the conventional form of harvesting stromal vascular fraction (SVF) called enzymatically digested SVF (E-SVF). Mechanical SVF (M-SVF) isolation has emerged as an alternative method, but it has also some limitations in terms of lower cell viability and diminished cell counts. To enhance the SVF qualitatively and quantitatively, we propose a novel concept called "hybrid-SVF," in which we combine M-SVF with the concentrated parts of adipose tissue after centrifugation, which is called stromal vascular matrix (SVM). Methods: Hybrid-SVF injection was applied as an adjunctive therapy to fat grafting in 88 patients and 11 samples were evaluated in the laboratory for cell count, viability and cell activity. Results: Experimental results determined that SVM part showed higher cellular activity. SVM and M-SVF showed higher cellular potency than E-SVF. Clinically, none of the patients required an additional session for fat grafting since there was no significant graft resorption. However, seven patients asked for further volume augmentation due to their individual preferences. No major complication was encountered. Conclusions: The usage of hybrid-SVF has a very high regenerative potential due to the ECM support and exceptionally high cell yield in addition to preserved cell potency. Although there are ongoing studies focusing on optimizing cell counts and further clinical applications, we believe that our preliminary results might create a paradigm shift in the area of regenerative fat grafting.

Use of Platelet Rich Plasma and Hyaluronic Acid in the Treatment of Complications of Achilles Tendon Reconstruction.

BACKGROUND: The platelet-rich plasma (PRP) and hyaluronic acid (HA) constitute a system of tissue growth that can regenerate damaged tissue. This study was performed to evaluate the effect of PRP and HA in treatment of complications of Achilles tendon reconstruction. METHODS: We selected ten patients affected by Achilles tendon injuries resulting from post-surgical complications subsequent to tenorrhaphy and have treated them with autologous PRP in combination with HA to evaluate the improvement of lesions with wound closure. RESULTS: The treatment with PRP and HA for post-surgical complications of Achilles tendon was effective in healing and regeneration of soft and hard tissues. The healing time was shortened, and the treated area preserved a satisfying strength in plantar flexion and extension of the ankle, denoting to a decisive improvement in texture and a more rapid healing and a good cutaneous elasticity, with a significant reduction of the costs of hospitalization and the pain already the immediate postoperatively. The functional rehabilitation in terms of deambulation and joint mobility was complete. CONCLUSION: The treatment we proposed allowed an easier and more rapid wound closure with excellent aesthetic improvement. Furthermore, the minimally invasive technique is well tolerated by patients.

Limb rescue: a new autologous-peripheral blood mononuclear cells technology in critical limb ischemia and chronic ulcers.

INTRODUCTION: Therapeutic angiogenesis by autologous-peripheral blood mononuclear cells (A-PBMNC) implantation has been shown to be a safe and effective treatment for critical limb ischemia (CLI). We herein report our investigation of the long-term efficacy of implantation of A-PBMNC produced by selective filtration to treat patients with CLI, for which surgical bypass and/or percutaneous transluminal angioplasty are not possible. MATERIALS AND METHODS: This is a prospective, and not a randomized, study based on a treated group who did not respond to conventional therapy (n=43) when implanted with A-PBMNC cells versus a historically matched control group. Patients of both groups were suffering from CLI Fontaine scale IV with chronic ulcers and various accompanying conditions (diabetes, heart disease, kidney failure, etc.). Treated patients were implanted with 12 mL of A-PBMNC, 0.2-0.3 mL for each bolus, collected by selective filtration from 120 mL of peripheral blood in the ischemic area of the limbs. Patients were not mobilized by granulocyte colony-stimulating factor, and the A-PBMNC treatment was repeated for a maximum of three times. RESULTS: The A-PBMNC-treated group showed a statistically significant improvement of limb rescue of 95.3% versus 52.2% of the control group (p<0.001), and the result had been maintained for 2 years. The A-PBMNC group also showed reduction in pain at rest, increased maximum walking distance, and healing of the wound, which led to an overall improvement in the quality of life. Post-treatment radiological studies showed an improvement of vascularization with the formation of new collateral and by histological findings. Within 2 years of follow-up, none of the patients whom we treated showed any major or systemic adverse effects. CONCLUSION: The local injection of A-PBMNC showed striking early and long-term effects together with a favorable safety profile, significantly decreasing the risk of amputation. Our results are comparable with published data obtained by injection of bone marrow mononuclear cells, but with a lot less invasive approach. Moreover the intraoperative selective filtration system we used is fast, safe, not operator dependent, and easy to use in a sterile operating theatre. This system aims to produce fresh A-PBMNC as a valuable treatment option, particularly for those difficult patients who cannot undergo revascularization.

Severe hidradenitis suppurativa treatment using platelet-rich plasma gel and Hyalomatrix.

Hidradenitis suppurativa (HS) can be a debilitating chronic disease. The underlying cause of the disease is still not clear. HS may be managed through numerous different medical or surgical procedures. Surgical treatment may consist of local excisions and reconstruction using a variety of methods: perforator flaps, skin grafts, local flaps, primary closure or secondary wound healing with vacuum and other devices. This report describes our experience with surgical excision and closure using platelet-rich plasma (PRP) gel and Hyalomatrix PA (HPA) in a patient with severe HS involving most of the body surface. We treated the patient with resection of severe HS of the nuchae and closure with PRP gel prepared with the RegenKit(®) to promote neovascularisation and HPA, a delivery system for hyaluronic acid, to induce a neodermis at the wound bed and to stimulate regeneration in a humid and protected environment. Complete wound healing was achieved after 2 months. The obtained result proved the efficacy of this treatment without complications. No recurrence was observed during the 1 year after the surgical procedure. Severe HS can be safely and effectively managed with wide excision, PRP gel and Hyalomatrix to achieve a successful outcome.

Spontaneous clostridial myonecrosis after pregnancy - emergency treatment to the limb salvage and functional recovery: a case report.

Clostridial myonecrosis (CM) is a rare, life threatening necrotizing infection of a skeletal muscle caused by Clostridium perfringens in the majority of cases. The diagnosis may be difficult because of few diagnostic and cutaneous signs early in its course. Standard therapy involves surgical debridements of a devitalized tissue and high-dose organism-specific antibiotic therapy. The hyperbaric oxygen has also showed its usefulness in the treatment of these infections. Autograft systems as tissue replacement, based on bioengineered materials, have been demonstrated to be safe and effective treatments for chronic wounds and a suitable physiotherapy is recommended for the recovery of functional impairments of upper extremities. We present a rare case of CM of right upper limb treated with a combination of standard treatments and new techniques.

Chronic ulcers: MATRIDERM(®) system in smoker, cardiopathic, and diabetic patients.

Diabetic ulcers and pressure ulcers represent a more frequent cause of chronic wounds in aging populations. It is estimated that approximately 15% of the diabetic population will develop diabetic ulcers during their life and over half of these patients develop an infection, often osteomyelitis, with 20% requiring amputation. The authors report a case of a 65-year-old woman affected by a post-traumatic loss of substance due to road accidents with soft tissue exposure (comprising muscle tendon) of the left knee combined with the fracture of the right fibula previously subjected to surgery and reconstruction of muscle tendon. The patient was affected by diabetes type II, hypertension, and ischemic heart disease. In 2008, she underwent a double bypass surgery and coronary angioplasty. Initially, the patient was treated with cycles of advanced dressings, with fibrinolytic ointments, hydrocolloid, and subsequently, when the bottom began granulated with fibrinolytic and idrocellulosa, Hydrofibra-Ag, and Ag-alginate, three times a week for 30 days. In the second step, the authors decided to treat the ulcer with the MATRIDERM system and auto skin graft. Following the first treatment, 7 days after the procedure, the authors found the reduction of the loss of substance until its complete closure. The wound's infection was evaluated by a buffer negative confirmation performed every 2 weeks four times. We obtained decrease of limb edema and full functional rehabilitation. The skin appeared renovated, with volume restoration and an improvement of the texture.

Regenerative surgery of the complications with Morton's neuroma surgery: use of platelet rich plasma and hyaluronic acid.

Morton's neuroma is an entrapment neuropathy of the plantar digital nerve. We treated five patients with wound dehiscence and tendon exposure, after Morton's neuroma surgery excision using a dorsal approach. In this article we describe our technique. From July 2010 to August 2011, at the Department of Plastic and Reconstructive Surgery, University of Rome 'Tor Vergata', five patients (four females and one male), with ages ranging between 35 and 52 years, were treated with a combination of PRP (platelet rich plasma) and HA (hyaluronic acid). Thirty days following surgery, all patients showed a complete healing of the wound. The use of this technique for the treatment of postoperative wound dehiscence and tendon exposure has proven as satisfactory.

Combined use of super-oxidised solution with negative pressure for the treatment of pressure ulcers: case report.

A 61-year-old patient was affected by flaccid paraplegia for 20 years because of post-traumatic medullar injury caused by an accidental fall, with stage IV sacral pressure ulcer for 3 years. The patient later developed stage IV sacral pressure ulcer. After 6 months, a new granulation tissue formation appeared in the wound and a reduction of its diameter was observed (length 20 cm, width 15 cm, depth 5 cm). We therefore treated the wound with PRP (platelet rich plasma) intra-lesion and peri-lesional injections. The wounds were covered with three-dimensional polymerised hyaluronic acid medicated biologic dressing. After the surgery, a moderate reduction in diameter and the depth was observed. Super-oxidised solution (SOS-Dermacyn) was applied to control infection locally together with negative pressure to control the exudate and the local bacteremia, to avoid infectious complications without application of systematic antibiotic therapy.
