Round Form-Stable Breast Implants: Diagnosis and Management of Complications.

Silicone gel breast implants have been used for breast augmentation and reconstruction since 1962. Since then, multiple generations of implants have been created in an effort to improve safety and efficacy. Before 1990, silicone gel implants were characterized as having thin shells and non-cohesive gel; however, since then devices are created with cohesive silicone gel and a variety of surfaces. Despite improvements, no implant will last forever; however, these devices are safe and effective based on numerous clinical and epidemiologic studies. As with all medical devices, complications using round form-stable implants for breast reconstruction can occur and will be reviewed in this article.

Validated Outcomes in the Grafting of Autologous Fat to the Breast: The VOGUE Study. Development of a Core Outcome Set for Research and Audit.

BACKGROUND: Autologous fat grafting is an important part of the reconstructive surgeon's toolbox when treating women affected by breast cancer and subsequent tumor extirpation. The debate over safety and efficacy of autologous fat grafting continues within the literature. However, work performed by the authors' group has shown significant heterogeneity in outcome reporting. Core outcome sets have been shown to reduce heterogeneity in outcome reporting. The authors' goal was to develop a core outcome set for autologous fat grafting in breast reconstruction. METHODS: The authors published their protocol a priori. A Delphi consensus exercise among key stakeholders was conducted using a list of outcomes generated from their previous work. These outcomes were divided into six domains: oncologic, clinical, aesthetic and functional, patient-reported, process, and radiologic. RESULTS: In the first round, 55 of 78 participants (71 percent) completed the Delphi consensus exercise. Consensus was reached on nine of the 13 outcomes. The clarity of the results and lack of additional suggested outcomes deemed further rounds to be unnecessary. CONCLUSIONS: The VOGUE Study has led to the development of a much-needed core outcome set in the active research front and clinical area of autologous fat grafting. The authors hope that clinicians will use this core outcome set to audit their practice, and that researchers will implement these outcomes in their study design and reporting of autologous fat grafting outcomes. The authors encourage journals and surgical societies to endorse and encourage use of this core outcome set to help refine the scientific quality of the debate, the discourse, and the literature. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Superior Pedicle Mammaplasty without Parenchymal Incisions after Massive Weight Loss.

BACKGROUND: After considerable weight loss, the breast suffers significant deformation. The ptotic breast is characterized by a lack of superior pole, tissue excess in the inferior pole, down-migration of nipple-areola complex (NAC) with redundancy of skin tissue. The authors describe a mastopexy technique based on a modulated and progressive reshaping, back rotation, and suspension of mammary gland parenchyma without parenchymal incisions. METHODS: Forty-five patients with bilateral moderate or severe breast ptosis underwent mastopexy from January 2011 to January 2014 with complete detachment of breast from the pectoralis major muscle and the plication of parenchyma without any parenchymal incision. Patients were followed up for one year, reporting any complication, and measuring the jugulum-NAC distance. The outcomes were assessed by the patients as well as the surgical team. RESULTS: The aesthetic outcomes were good or excellent in all patients. The new mammary contour and the distance between the jugular fossa and the nipple were stable during this time with a good filling of upper pole. No major complications were reported. CONCLUSIONS: This technique gave good breast shape, long-term projection, and upper pole fullness, without parenchymal incisions. It restores breast shape and projection, especially in post-bariatric patients. A similar technique has not been described yet.

RESULTADO: O volume manteve-se estável a partir do segundo mês, e não houve complicações no pós-operatório. Os exames de imagem não apresentaram alterações patológicas. Foram selecionados 24 artigos relacionados. DISCUSSÃO: Dos 24 artigos, só há dois artigos prospectivos não controlados, mas, de maneira geral, não há problemas no diagnóstico nos exames por imagem, não há aumento de potencial cancerígeno, e os resultados são bons nas séries de casos. CONCLUSÃO: O procedimento é reprodutível, seguro e eficaz, consolidando-se como uma indicação no tratamento reparadora da mama e uma opção no aumento estético. Entretanto, uma curva de aprendizado mais longa pode ser necessária, para evitar complicações e atingir bons resultados.

INTRODUCTION: The technique and technology lipoaspirate autotransplantation to the breast with the aim of aesthetic appearance and reconstruction has strongly advanced; further, its acceptance by doctors and patients has also improved. The author reports cosmetic breast augmentation and performed a literature review, focusing on the efficacy, carcinogenic potential, and imaging diagnosis. METHOD:A literature review was performed using English-language articles from the PubMed database and the Brazilian Journal of Plastic Surgery (RBCP); in addition, case series of the initial experience of the author has been described. RESULTS: The volume remained stable from the second month, and there were no postoperative complications. Imaging did not show any pathological alterations. In all, 24-related articles were selected. DISCUSSION: Among the 24 articles, only two prospective non-controlled studies were found, but overall, imaging diagnostic tests did not reveal problems, the carcinogenic potential was not increased, and case series had positive results. CONCLUSION: The procedure is reproducible, safe and effective, and reinforces the use of this technique in breast reconstruction and as an option in cosmetic breast augmentation. However, it may require a longer learning curve to avoid complications and achieve good results.

Mamoplastia pós-cirurgia bariátrica usando suporte protético complementar de contenção glandular / Breast augmentation after bariatric surgery by using complementary prosthetic support for glandular containment

INTRODUÇÃO: A pele de pacientes emagrecidas pós-cirurgia bariátrica apresenta alterações estruturais e proteômicas e não resiste ao peso das mamas, levando-as à flacidez residual precoce, exigindo suporte auxiliar. O objetivo é aplicar suporte auxiliar de lâmina de polipropileno não absorvível mais poliglecaprone absorvível ou lâmina de silicone de bustos, em forma de "soutien interno" como auxiliar de sustentação da pele, para manutenção da forma das mamas, e flacidez no mínimo comparável a outras pacientes sem emagrecimento pela cirurgia bariátrica. MÉTODOS: Nove pacientes foram submetidas à mamoplastia em T invertido com modelagem dos tecidos mamários, com redução do volume e envolvidos com lâmina de sustentação auxiliar. RESULTADOS: Não houve flacidez precoce e em observação de até 4 anos ela era aceitável. Uma delas apresentou seroma, drenado com boa resolução. Serão operadas outras 24 pacientes dentro do protocolo, acompanhadas e observadas por 2 anos com controle mamográfico, ultrassônico e ressonância magnética. CONCLUSÃO: A mamoplastia redutora pós-cirurgia bariátrica requer suporte extra à glândula mamária. A pele estruturalmente alterada não suporta o seu peso e haverá flacidez precoce.

INTRODUCTION: The skin presents structural and proteomic changes after bariatric surgery and cannot withstand the weight of the breasts, which leads to early residual flaccidity, requiring auxiliary support. The goal is to apply a nonabsorbable polypropylene-poliglecaprone absorbable auxiliary mesh support or Bustos silicone sheet, in the form of an "internal brassiere," to support the skin in order to maintain the shape and flaccidity of the breasts comparable with those of normal breasts. METHODS: Nine patients underwent mammoplasty in inverted T with modeling of tissue implants, reduction of breast volume, and wrapping with an auxiliary support mesh. RESULTS: Flaccidity was not observed at an early stage and the condition was acceptable for up to 4 years of follow-up. One of the patients had a seroma, which was drained with good resolution. Another 24 patients will be operated according to the protocol and observed for 2 years by using mammography, ultrasonography, and magnetic resonance imaging. CONCLUSION: Reduction mammoplasty after bariatric surgery requires additional support for the mammary gland. The structurally altered skin could not support the weight of the breasts, resulting in early flaccidity.

Breast sharing: New perspectives on an old method.

BACKGROUND: Many techniques have been described for breast reconstruction after mastectomy throughout the decades. In many cases, with excess tissue being discarded, a significant reduction of the contralateral breast was needed for symmetry. Described by Marshall as a one-staged, autologous, non-microsurgical breast reconstruction technique, this method was used in perforator flaps as a breast-sharing technique. METHODS: Between June 2011 and January 2014, the breast-sharing technique was performed in seven patients with simple mastectomy, delayed breast reconstruction, and willingness for autologous non-microsurgical breast reconstruction. All the participants in this study received preoperative oncological screening with ultrasound, magnetic resonance imaging, or mammography, which revealed the absence of pathologic imaging in the donor breast. RESULTS: The experiences of seven patients who underwent breast reconstruction surgery through breast-sharing technique are presented. Due to venous congestion, one of the patients (14%) suffered major complications with total loss of the flap. A total of four patients (57%) incurred minor complications with little to no repercussions on the final outcome. The functional and aesthetic outcomes were very satisfactory, and only one patient required a second touch-up surgery for lipofilling due to unsatisfactory breast volume. Regular follow-ups were done by the oncologist with no recurrences found up to the present. CONCLUSIONS: Using contralateral breast as the donor site, this article presents the first case series for one-stage mammarian reconstruction. With some complications but good aesthetic outcomes, this method has been shown as another available method for breast reconstruction in patients with hypertrophic and ptotic breast.

Xenogenic transplantation of human breast adipose-derived stromal vascular fraction enhances recovery of erectile function in diabetic mice.

The adipose tissue-derived stromal vascular fraction (SVF) is an ideal source of stem and stromal cells. The aim of this study was to examine whether and how xenogenic transplantation of human breast SVF restores erectile function in diabetic mice. Human SVF was isolated from five patients (age, 20-45 yr) undergoing reduction mammoplasty. Eight-week-old C57BL/6J mice were used, and diabetes was induced by intraperitoneal injection of streptozotocin. At 8 wk after induction of diabetes, the animals were randomly distributed into controls and diabetic mice treated with a single intracavernous injection of PBS, human SVF at different concentrations, or human SVF lysate. Two weeks later, erectile function was measured by cavernous nerve stimulation, and the penis was then harvested for biochemical examinations. Erectile function was significantly improved in diabetic mice treated with human SVF (2 × 10(5), 5 × 10(5), and 1 × 10(6) cells/20 µl) and SVF lysate. Human SVF treatment in diabetic mice significantly increased cavernous endothelial and smooth muscle cell contents, induced eNOS phosphorylation, and restored penile nNOS-positive nerve fibers. Human SVF lysate induced secretion of angiogenic factors and expression of their receptors. Human SVF did not increase serum levels of proinflammatory cytokines. A limitation of this study was that the exact composition of the human SVF was not examined. In summary, xenogenic transplantation of human SVF did not induce systemic inflammation and successfully improved erectile function in diabetic mice through enhanced penile angiogenesis and neural regeneration.

Breast reconstruction with autologous fat graft mixed with platelet-rich plasma.

BACKGROUND: The purpose of this study was to review the authors' experience of fat grafting, evaluating the effects related to the use of fat grafting with platelet-rich plasma (PRP) in the improvement of fat volume in breast reconstruction and comparing the results with a control group (only centrifuged fat grafting). METHODS: A total of 50 patients aged between 19 and 60 years affected by breast soft-tissue defects were analyzed at the Plastic and Reconstructive Department of the University of Tor Vergata. They were treated with fat grafting + PRP. The control group (50 patients with breast soft-tissue defects) were treated with centrifuged fat grafting injection according to Coleman's procedure. RESULTS: The patients treated with PRP added to the autologous fat grafts showed a 69% maintenance of the contour restoring and of 3-dimensional volume after 1 year, whereas the patients of the control group treated with centrifuged fat grafting showed a 39% maintenance. CONCLUSION: PRP mixed with fat grafting leads to an improvement in maintaining breast volume in patients affected by breast soft-tissue defects.

Arterite actínica de artéria subclávia: relato de caso e revisão de literatura / Actinic arteritis of subclavian artery: case report and literature review

Diversas são as complicações possíveis da radioterapia na adjuvância do tratamento de neoplasias. Lesões actínicas de artéria subclávia em pacientes submetidos a este tipo de tratamento para neoplasia de mama são complicações conhecidas, porém com poucos relatos de casos publicados. No presente relato, descrevemos um caso de oclusão de artéria subclávia direita em paciente submetida à radioterapia para tratamento de neoplasia de mama, tratada com a revascularização convencional, com interposição de enxerto de politetrafluoretileno (PTFE). Na revisão da literatura realizada, foram encontrados doze casos descritos que evidenciaram diferentes opções terapêuticas. Concluímos que a arterite actínica de artéria subclávia é uma doença incomum, entretanto sua hipótese deve ser aventada em todos os pacientes com isquemia de membro superior já submetidos a tratamento de radioterapia.

Several complications may occur as a consequence of adjuvant radiotherapy for cancer. One of these complications is actinic lesions of the subclavian artery in patients undergoing radiotherapy for breast cancer; however, there are few reported cases. In the present case report, we describe a case of right subclavian artery occlusion in a patient undergoing radiotherapy for breast cancer. Occlusion was treated by means of conventional artery bypass with interposition graft with polytetrafluoroethylene (PTFE). Our extensive review of the literature revealed 12 reported cases showing the different treatment options performed. We concluded that actinic arteritis of the subclavian artery is an uncommon condition; however, its presence should be considered in all patients with upper limb ischemia who underwent radiotherapy.

High and low mammographic density human breast tissues maintain histological differential in murine tissue engineering chambers.

Mammographic density (MD) is the area of breast tissue that appears radiologically white on mammography. Although high MD is a strong risk factor for breast cancer, independent of BRCA1/2 mutation status, the molecular basis of high MD and its associated breast cancer risk is poorly understood. MD studies will benefit from an animal model, where hormonal, gene and drug perturbations on MD can be measured in a preclinical context. High and low MD tissues were selectively sampled by stereotactic biopsy from operative specimens of high-risk women undergoing prophylactic mastectomy. The high and low MD tissues were transferred into separate vascularised biochambers in the groins of SCID mice. Chamber material was harvested after 6 weeks for histological analyses and immunohistochemistry for cytokeratins, vimentin and a human-specific mitochondrial antigen. Within-individual analysis was performed in replicate mice, eliminating confounding by age, body mass index and process-related factors, and comparisons were made to the parental human tissue. Maintenance of differential MD post-propagation was assessed radiographically. Immunohistochemical staining confirmed the preservation of human glandular and stromal components in the murine biochambers, with maintenance of radiographic MD differential. Propagated high MD regions had higher stromal (p = 0.0002) and lower adipose (p = 0.0006) composition, reflecting the findings in the original human breast tissue, although glands appeared small and non-complex in both high and low MD groups. No significant differences were observed in glandular area (p = 0.4) or count (p = 0.4) between high and low MD biochamber tissues. Human mammary glandular and stromal tissues were viably maintained in murine biochambers, with preservation of differential radiographic density and histological features. Our study provides a murine model for future studies into the biomolecular basis of MD as a risk factor for breast cancer.

Use of the ipsilateral breast in anterolateral chest wall reconstruction.

Chest wall ablative surgery often requires autologous tissue transfer to reconstruct the resulting defect. The female breast is commonly of a suitable size to provide anteromedial chest wall coverage as a pedicled dermoglandular flap. In anterolateral defects the latissimus dorsi or serratus anterior flaps are often the preferred choice, in the absence of which free tissue transfer is an alternative technique. However these options may not always be available or suitable. A 90-year-old female presented with a large chest wall mass in keeping with recurrence of oesophageal squamous cell carcinoma in the thoracotomy scar following a previous oesophagectomy. The latissimus dorsi and serratus anterior muscles were transected during the previous thoracotomy. Following complete resection, the ipsilateral breast was used as a rotational dermoglandular flap to provide coverage over the exposed ribs. The use of breast as a local flap is an alternative option in anterolateral chest wall reconstruction.

A novel method for growing human breast epithelium in vivo using mouse and human mammary fibroblasts.

A novel system is described for studying the growth of normal human mammary epithelium in vivo as grafts in athymic nude mice. The key feature of this model is reconstitution of the epithelial-stromal interactions required for normal growth and differentiation of the human mammary epithelium, which produces ducts that are comparable to those in the normal human mammary gland. Human breast epithelial organoids were combined with mammary fibroblasts from mouse or human origin in collagen gels, which were subsequently transplanted under the renal capsule of female nude mice hosts. The resulting grafts showed an increase in the ductal density compared with that observed previously. These ducts expressed appropriate markers for luminal and myoepithelial cells and steroid receptors. Treatment of the host with diethylstilbestrol or estradiol and progesterone significantly increased the number of ducts observed and increased cell proliferation. The grafts also displayed production of beta-casein and milk fat globule membrane protein when the hosts were allowed to become pregnant. This model allows for a variety of epithelial and stromal cells to be used in combination, which would aid in understanding key factors that regulate normal human mammary gland development.

A new contralateral split-breast flap for breast reconstruction and its salvage after complication: an alternative for select patients.

Different approaches to breast reconstruction have been described and nowadays nearly optimized. One major aim in further developments is to reduce donor site morbidity as low as possible. Theoretically, the lowest donor site morbidity could be achieved by using tissue that would be normally discarded during an operation necessary for a different reason. The authors present a new method of breast reconstruction in a mastectomy patient who needed a reduction mammaplasty on the remaining side in addition to the reconstruction. A single-stage split-breast flap from the reduced contralateral side pedicled on its internal mammary perforators was used, thus lowering donor site morbidity by using otherwise discarded tissue. The technical details, patient selection, advantages, possible pitfalls, management of complications, and the risk factors for contralateral malignancy are discussed.

Estrogen and progesterone receptors can be maintained in normal human breast epithelial cells in primary culture and after transplantation into nude mice.

The estrogen and progesterone receptor expression was determined in breast epithelial cells from reduction mammoplasty specimens. Only a subset of the luminal epithelial cell population was found to be positive for these receptors. When these cells were subsequently cultured in 3-dimensional collagen gel system (in vitro model) or transplanted into nude mice (in vivo model), the cells retained their ability to express both receptors in these experimental systems. The maintenance of primary normal human breast epithelial cells expressing the estrogen and progesterone receptors in experimental systems has not been reported previously.

[The use of an inferior dermo-glandular flap in Thorek's technique, based on a series of 21 cases]. / Utilisation d'un lambeau dermo-glandulaire inférieur dans la technique de Thorek. A propos de 21 cas.

Thorek's technique, first described in 1922 for breast reductions, has been progressively replaced by techniques using a dermoglandular pedicle. This first technique is still performed today in cases of major hypertrophy. But the major disadvantage is the tendency for the breast to be too flat post-reduction. We tried to correct this problem by preserving an inferior dermoglandular flap rolled into a cone shape before positioning it within the bulk of the breast, thus giving a better projection. The authors present a series of 21 patients operated by this technique with a median follow-up of two years. The preliminary results are encouraging and we think that this procedure is a treatment of choice in cases of gigantomastia.

Further clinical experience in permanent lip augmentation using autologous breast implant capsule.

Lip augmentation is a well tolerated procedure that can lead to a more youthful appearance. Autologous tissue offers the safest and most long lasting results. Recently, a new source of autologous tissue, breast implant capsule, was described in the performance of permanent lip augmentation. Long term data in thirteen patients is presented and documents persistence of volume enhancement of over one year postoperatively.
