ABSTRACT

Há 50 anos, no Jefferson Davis Hospital, em Houston (EUA), realizou-se a primeira cirurgia de mamoplastia de aumento com implantes de silicone. Atualmente, o avanço da tecnologia médica disponibilizou no mercado implantes de diversas formas e texturas, assim como permitiu o desenvolvimento de inúmeras técnicas para a realização desta cirurgia. Este procedimento cirúrgico pode apresentar algumas complicações locais imediatas e tardias no pós-operatório. Por se tratar de um implante constituído de material biocompatível ao organismo, mesmo com 50 anos de evolução, deve-se sempre estudar e, se possível, relatar as possíveis complicações que possam ocorrer. O objetivo deste artigo é revisar as complicações mais frequentes que ocorrem no pós-operatório das mamoplastias de aumento com implante de silicone, bem como relatar o caso de uma complicação atípica, doença de Mondor, no pós-operatório desta cirurgia.


The first breast augmentation surgery with silicone implants was performed at the Jefferson Davis Hospital in Houston (USA) about 50 years ago. Recent advances in medical technology have made implants of various shapes and textures commercially available and led to the development of numerous techniques for performing this surgery. However, this surgical procedure may have some immediate and long-term local complications . Since the implant is made of biocompatible material , it is important to investigate and report complications that occur despite the 50 years of research. The purpose of this study was to review the most frequent complications occurring after breast augmentation surgery with silicone implants and to report a case of an unusual complication, Mondor's disease.

ABSTRACT

Objective: The rupture of mammary protheses PIP (poly-implant-prothese) caused an alarm, settling in Spain a protocol for the management of patients. As hospital unit of reference for the management, monitoring and treatment of patients carrying PIP breast implants, we propose objective to make a descriptive study of the current situation in our country and compare it to the hitherto described in the literature. Method: We conducted a transversal study of all patients who came during the years 2012 and 2013, to the Unit of Mammary Pathology of the Universitary General Hospital of Elche. Results: With a total of 285 women, we observed a high rate of implant rupture (50.2 percent) asymptomatic most (84.6 percent). Fact that the year 2006 had the highest percentage of breakage and the appearance of siliconomas. Conclusions: Our series confirms rupture rate similar to that described in the literature for PIP breast implants. We observed a higher percentage of breakage from the year 2006, coinciding with the period of manufacture described poorer quality of these implants. Axillary siliconomas were evident in 35.1 percent of patients, the only locally axillary symptoms.

ABSTRACT

PURPOSE: To evaluate the effect of propranolol on capsular architecture around silicone implants by measuring the inflammation, capsular thickness, and collagen fiber density, using a guinea pig experimental model. METHODS: Thirty six adult male guinea pigs randomly divided into two groups (n=18) were used. Each one received a silicone implant with textured-surface. The capsular tissue around implants from untreated or treated animals with the beta-adrenoceptor antagonist propranolol (10 mg/kg, dissolved in daily water) were analyzed for inflammation by histological scoring, capsular thickness by computerized histometry, and collagen fibers type I and Type III density by picrosirius polarization at different time points (7, 14 or 21 days after silicone implantation). RESULTS: Propranolol treatment reduced inflammation and impaired capsular thickness and delayed collagen maturation around the textured implant. CONCLUSION: Propranolol reduces the risk of developing capsular contracture around silicone implants with textured surface. .

ABSTRACT

BACKGROUND: Lower limb amyotrophy is a serious deformity that is often disabling and causes esthetic problems such as asymmetries and changes in the shape and contour of the legs. The present study evaluated the use of silicone implants for the correction of lower limb amyotrophy. METHODS: Women who underwent surgical correction of lower limb amyotrophy with silicone implants between 2002 and 2009 at the Plastic Surgery Service of Instituto Ivo Pitanguy at the 38th Nursing Service of Santa Casa da Misericórdia, Rio de Janeiro and at their associated services were retrospectively reviewed. RESULTS: Five cases were studied and the results were retrospectively assessed. Follow-up ranged from 3 months to 2 years after surgery until the last postoperative visit. In 4 of 5 patients, the desired result was obtained after a single surgical procedure, and no patient developed capsular contracture, compartment syndrome, circulatory disorders, neurological disorders, or infections. CONCLUSIONS: Calf augmentation in patients with lower limb amyotrophy did not correct the associated functional deficit, but resulted in a high level of satisfaction with regard to the esthetic improvement of the limb, thus improving the quality of life of these patients.


INTRODUÇÃO: As amiotrofias dos membros inferiores são deformidades por vezes incapacitantes, mas que trazem aos pacientes problemas estéticos, como assimetrias e alterações da forma e contorno das pernas. Este estudo teve como objetivo avaliar a aplicabilidade do uso de implantes de silicone para correção de amiotrofias de membros inferiores. MÉTODO: Estudo retrospectivo de pacientes, todas do sexo feminino, submetidas a correção cirúrgica de amiotrofia de pernas com a utilização de implantes de silicone, entre 2002 e 2009, no Serviço de Cirurgia Plástica do Instituto Ivo Pitanguy, na 38ª Enfermaria da Santa Casa da Misericórdia do Rio de Janeiro e em serviços associados. RESULTADOS: Foram analisados 5 casos. A maioria dos resultados foi avaliada de maneira retrospectiva. O tempo de acompanhamento variou de 3 meses a 2 anos, desde a cirurgia até a última consulta pós-operatória. Do total de pacientes, 4 apresentaram resultado desejado em apenas um procedimento cirúrgico e nenhuma paciente apresentou contratura capsular, síndrome compartimental, alterações circulatórias, alterações neurológicas ou infecção. CONCLUSÕES: O aumento das panturrilhas em pacientes portadoras de amiotrofias de membros inferiores não proporcionou modificações no tocante ao deficit funcional prévio. Todavia, essas pacientes, geralmente bastante castigadas pela doença de base, apresentam índice de satisfação muito elevado com a melhoria estética do membro, otimizando, dessa forma, a qualidade de vida dessas pacientes.

ABSTRACT

A breast implant is a prosthesis used to enhance the size of a woman's breast. Silicone implants are most commonly used, but as with all surgical implants it has some complications. The question is whether it can induce breast cancer? During the last year, a case of reconstructed breast with prosthesis which leaked was presented. The aim of this report is to review current literature to evaluate whether there are reported correlations between breast cancer and breast implants. The conclusion derived from this report is that there is no available evidence directly correlating breast cancer to breast implants

ABSTRACT

PURPOSE: Evaluating histologically the silicone peri-implant coated by polyurethane inflammation associated to the use of anti-microbial and bacterial contamination. METHODS: It was used 35 Wistar rats. The animals were divided in seven groups: I - Control; II - implant cavity contamination with10 bacteria/ml; III - implant cavity contamination with 10 bacteria/ml; IV - implant cavity contamination with 10 bacteria/ml; V - identical contamination to group II and implant immersions in anti-microbial solution; VI - identical contamination in group III and implant immersions in the anti-microbial solution; VII - identical contamination of group IV and implant immersions in anti-microbial solution. It was evaluated morphometrically the peri-implant capsules after 30 days of introduction. RESULTS: The factors with more discriminating power were the giants cells of a strange body and the mononuclear. There was no correlation between the bacterial concentrations and the histological alterations. CONCLUSION: 1) The histological standard of the inflammatory reaction around the silicone implant coated with polyurethan is chronic granulomatosis type of a strange body; 2) There isn´t correlation between concentration of Staphylococcus epidermidis and histological changes; 3) The use of anti-microbial solution decreased the mononuclear cell reactions, with the increase of giant cells in a strange body.


OBJETIVO: Avaliar, histologicamente, a reação inflamatória aos implantes de silicone revestidos por poliuretano, com contaminação bacteriana, associada ou não ao uso de antimicrobianos. MÉTODOS: Utilizou-se 35 ratos Wistar. Os animais foram divididos em 7 grupos: I- Controle, II- contaminação da cavidade do implante com 10¹ bactérias/ml, III- contaminação da cavidade do implante com 10³ bactérias/ml, IV- contaminação da cavidade do implante com 10(5) bactérias/ml, V- contaminação idêntica ao grupo II e imersão dos implantes em solução antimicrobiana, VI- contaminação idêntica do grupo III e imersão dos implantes em solução antimicrobiana, VII- contaminação idêntica do grupo IV e imersão dos implantes em solução antimicrobiana. Avaliou-se morfometricamente as cápsulas peri-implantes após 30 dias da introdução. RESULTADOS: Os fatores com maior poder discriminante foram as células gigantes de corpo estranho e os mononucleares. Não houve correlação entre as concentrações bacterianas e as alterações histológicas. CONCLUSÕES: 1) O padrão histológico da reação inflamatória ao redor dos implantes de silicone revestidos com poliuretano é do tipo crônica granulomatosa de corpo estranho; 2) Não há correlação entre a concentração de bactérias Staphylococcus epidermidis e as alterações morfométricas; 3) O uso de solução antimicrobiana diminui a reação de células mononucleares, com aumento de células gigantes de corpo estranho.

ABSTRACT

Se presentan dos casos clínicos, de sexo femenino, a quienes se inyectó silicona líquida en las mamas, con el propósito de aumentar el volumen mamario perdido después de la lactancia. Se describen los efectos de la inyección en las mamas, el manejo quirúrgico y la evolución postoperatoria. La inyección de silicona líquida en el tejido mamario está contraindicada. Sus deletéreos efectos han sido evidenciados a corto y largo plazo. Pese a estas consideraciones, su uso por profesionales médicos y no médicos y sus graves efectos continúan siendo una realidad. El manejo de sus complicaciones es complejo, se han recomendado alternativas médicas como quirúrgicas, ninguna de las cuales ha logrado eliminar totalmente los tejidos comprometidos. Es así como la mejor forma de prevenir sus consecuencias es la difusión de información a quienes potencialmente pudieran solicitar la inyección de silicona líquida como a los que pudieran llevarla a cabo.

ABSTRACT

The increase in the utilization of silicone breast implants for recontruction and cosmetic purposes, has led to a great deal of discussion as to the possible complications resulting from their presence in the body. Some of the problems are related to the fibrous capsule (capsule contracture) and/or to the patient's immunologic response. The authors propose the utilization of an easily approachable technique for changing or removing breast implants, by removing the capsule and implant in one piece, the so-called "capsulectomy without capsulotomy". The objective of the study is to describe the procedure in detail, showing its advantages and risks and correlate data with the pertinent literature.

ABSTRACT

O silicone e utilizado em cirurgia plastica reconstrutiva desde a decada de 60, sendo que os implantes mamarios de silicone evoluiram a posicao de destaque pelo seu uso frequente em cirurgias esteticas nos ultimos 25 anos, chegando ao conhecimento e aceitacao do publico em geral. Nos ultimos 4 anos, grande controversia no uso destes implantes surgiu, desde que o Food and Drug Administration (FDA) dos Estados Unidos da America desaconselhou a utilizacao dos mesmos em cirurgias que nao tivessem o intuito de reconstrucao mamaria pos-mastectomia, devido a complicacoes locais, a um suposto atraso na deteccao de cancer de mama e principalmente ao desenvolvimento de doencas autoimunes. o presente estudo tem por objetivo...
