Chest wall reconstruction using abdominal rectus and latissimus dorsi muscle flaps: case report

INTRODUCTION: Chest wall reconstruction remains one of the great plastic surgery repair challenges. The present work aims to report on cases of chest wall reconstruction using myocutaneous flaps after wall resection due to tumor/osteomyelitis. METHODS: Four patients were included, among which three presented with osteomyelitis and the other presented with sarcoma; both of these conditions affected the chest wall. Each patient underwent wall resection and reconstruction using myocutaneous flaps from the latissimus dorsi (two cases) and abdominal rectus (two cases). RESULTS: The flaps used were sufficient for skin-muscle covering and maintained good vitality. Partial flap injury occurred in one case. Chest cavity stability was preserved. CONCLUSIONS: The use of the above flaps to repair chest defects was satisfactory with the aim of covering the skin and providing well-vascularized muscles, the latter of which was fundamental to preventing local infection

Análise dos resultados estéticos na reconstrução mamária com TRAM ipsilateral vs. contralateral Comparison of the aesthetic outcomes of breast reconstruction by using ipsilateral or contralateral TRAM flaps

INTRODUÇÃO: A reconstrução mamária com retalho do músculo reto abdominal (TRAM, do inglês transverse rectus abdominis myocutaneous) tem se tornado um procedimento comumente realizado desde a década de 1990. O TRAM ipsilateral vem demonstrando ser tão seguro quanto o retalho contralateral na reconstrução mamária. Entretanto, estudos avaliando o resultado estético com as duas técnicas são escassos na literatura. A proposta deste estudo é comparar os resultados cosméticos entre os retalhos pediculados ipsilateral e contralateral. MÉTODO: Foi realizada avaliação prospectiva de 29 pacientes submetidas a reconstrução imediata com TRAM ipsilateral e contralateral. Os grupos foram comparados entre si, analisando-se os resultados estéticos. RESULTADOS: O estudo incluiu 29 pacientes, com média de idade foi 43 + 7 anos. O grupo 1 (TRAM ipsilateral) apresentou o sulco inframamário bem definido em 91,7% dos casos, comparativamente a 52,9% no grupo 2 (TRAM contralateral). Observou-se abaulamento na região xifoide em 8,3% dos pacientes do grupo 1 e em 23,5% dos pacientes do grupo 2. A diferença na forma global da mama reconstruída não foi importante, com 66,7% e 70,6% de simetria nos grupos 1 e 2, respectivamente. CONCLUSÕES: O TRAM ipsilateral demonstrou melhor manutenção do sulco inframamário e menor abaulamento na região xifoide. Entretanto, a forma global da mama e a projeção do polo inferior da mama foram similares entre os dois grupos.BACKGROUND: Breast reconstruction by using the rectus abdominis muscle (transverse rectus abdominis myocutaneous, TRAM) flaps is a common procedure that has been performed since the 1990s. Ipsilateral TRAM flaps were proven to be as safe as contralateral flaps for breast reconstruction. However, studies comparing the aesthetic outcomes of the two procedures are poorly described in the literature. The aim of this study was to compare the cosmetic outcomes of ipsilateral and contralateral pedicled flaps. METHODS: We prospectively evaluated 29 cases of immediate reconstruction with ipsilateral (group 1) or contralateral (group 2) TRAM flaps. The aesthetic outcomes were analyzed and the two groups were compared. RESULTS: The average age of the patients was 43 ± 7 years. In group 1 (ipsilateral TRAM), 91.7% of the patients presented a well-defined inframammary fold, as compared to 52.9% of the patients in group 2 (contralateral TRAM). In group 1, 8.3% of patients showed xiphoid bulges, whereas they were observed in 23.5% of patients in group 2. The difference in the overall shape of the reconstructed breast was not significant; symmetry was observed in 66.7% and 70.6% of patients in groups 1 and 2, respectively. CONCLUSIONS: Ipsilateral TRAM flaps allow better preservation of the inframammary fold and cause less xiphoid bulge. However, the overall shape of the breast and the projection of its lower pole were similar between the two groups

Impacto da radioterapia adjuvante no resultado cosmético da reconstrução mamária imediata com retalho TRAM Impact of adjuvant radiotherapy on the cosmetic outcome of immediate breast reconstruction performed using a transverse rectus abdominis myocutaneous flap

INTRODUÇÃO: O efeito da radioterapia adjuvante após a reconstrução mamária com retalhos autólogos é controverso. O objetivo deste estudo é analisar se a radioterapia pós-operatória causa alterações volumétricas e cosméticas após a reconstrução mamária imediata com retalho do músculo reto abdominal (TRAM, do inglês transverse rectus abdominis myocutaneous). MÉTODO: No total, foram avaliadas 25 pacientes submetidas a reconstrução autóloga com retalho TRAM pediculado pós-mastectomia por câncer de mama e radioterapia adjuvante. Os resultados estéticos tardios foram coletados após o intervalo mínimo de 6 meses posteriormente ao esquema completo da radioterapia. RESULTADOS: A média de idade das pacientes foi de 42,2 anos, variando de 30 anos a 53 anos. Duas (8%) perdas completas do retalho ocorreram por necrose gordurosa maciça, duas (8%) pacientes evoluíram com contratura do retalho e perda volumétrica, e 52% das pacientes apresentaram alterações cutâneas. Entretanto, a maioria das pacientes (84%) não evoluiu com perda significativa do volume inicial do retalho ou com distorção do contorno e contração do retalho. CONCLUSÕES: O resultado cosmético após a reconstrução mamária imediata com retalho TRAM irradiado foi aceitável, comparativamente aos dados descritos na literatura. Esses achados indicam que os retalhos podem sofrer distorções de contorno pela contração, além de perda volumétrica significativa em pacientes candidatas à reconstrução com TRAM e necessidade de radioterapia adjuvante pós-mastectomia. Assim, as complicações tardias da irradiação pós-operatória devem ser consideradas nesse contexto.BACKGROUND: The outcome of adjuvant radiotherapy performed after breast reconstruction using autologous flaps is controversial. In this study, we aimed to assess whether postoperative radiotherapy would induce volumetric and cosmetic changes after immediate breast reconstruction performed using a transverse rectus abdominis myocutaneous (TRAM) flap. METHODS: We evaluated 25 patients who were previously diagnosed with breast cancer and underwent post-mastectomy autologous reconstruction with a pedicled TRAM flap followed by adjuvant radiotherapy. Late aesthetic results were recorded starting 6 months after the completion of a full course of radiotherapy. RESULTS: The average patient age was 42.2 years (range, 30-53 years). Two (8%) complete flap losses occurred due to massive fat necrosis. Two (8%) patients exhibited flap contracture and volume loss, whereas skin changes were observed in 52% of patients. Most of the patients (84%), however, had no significant initial flap volume loss, contour distortion, or flap contraction . CONCLUSIONS: The cosmetic result obtained in the present study by immediate breast reconstruction performed using an irradiated TRAM flap was satisfactory compared to the data described in the literature. These findings suggest that the flap contours may be distorted by contraction and that significant volume losses can be observed in patients who may be candidates for TRAM flap reconstruction and require post-mastectomy adjuvant radiotherapy. Thus, in these circumstances, late complications due to postoperative irradiation should be considered

Técnica simples e segura para a reconstrução areolopapilar com tatuagem intradérmica Simple and safe technique for nipple-areola reconstruction with intradermal tattoo

INTRODUÇÃO: A reconstrução do complexo areolopapilar (CAP) constitui o passo final na criação da neomama, com o objetivo de aproximá-la da mama contralateral após a mastectomia. A restauração do CAP tem sido historicamente um procedimento feito em estágios, com a reconstrução da papila realizada por meio de enxertos ou retalhos locais, previamente, e da aréola, posteriormente, buscando a coloração adequada. Atualmente, a utilização da tatuagem areolar está alcançando popularidade cada vez maior, comparativamente às técnicas tradicionais. O objetivo deste trabalho é descrever a técnica e os equipamentos utilizados para a tatuagem intradérmica em pacientes mastectomizadas, realizada no Serviço de Cirurgia Plástica e Microcirurgia Reconstrutiva do Hospital Universitário Walter Cantídio (Fortaleza, CE, Brasil). MÉTODO: O presente trabalho descreve os passos para a realização do procedimento reparador utilizando a tatuagem areolar permanente com equipamento convencional de tatuagem artística profissional. O procedimento foi aplicado em 10 pacientes submetidas a reconstrução mamária pós-mastectomia. RESULTADOS: O método demonstrou as vantagens da simplicidade técnica do procedimento, não requerendo internamento nem resultando em morbidade de áreas doadoras. CONCLUSÕES: A tatuagem do CAP é um procedimento seguro, rápido, com baixa morbidade e bons resultados na finalização da reconstrução mamária.BACKGROUND: The final step in the creation of the neo-breast is reconstruction of the nipple-areolar complex (NAC), which is aimed toward bringing the appearance of the NAC closer to that of the contralateral breast following mastectomy. NAC restoration has historically been a stepwise procedure, in which reconstruction of the nipple by the use of grafts or local flaps was followed by reconstruction of the areola to achieve the correct color. Currently, the popularity of the areolar tattoo is increasing compared to traditional techniques. The aim of this study was to describe the technique and equipment used for intra-dermal tattooing in mastectomized patients at the Plastic Surgery and Reconstructive Microsurgery Service of the Walter Cantídio University Hospital (Fortaleza, CE, Brazil). METHODS: This study describes the steps of the repair procedure by using permanent areolar tattooing with conventional equipment from a professional tattoo artist. The procedure was used in 10 patients undergoing post-mastectomy breast reconstruction. RESULTS: The advantages of this method included the technical simplicity of the procedure, the ability to use this procedure in outpatients, and the lack of morbidity of the donor areas. CONCLUSIONS: Tattooing the NAC is a safe, fast procedure with low morbidity and good results of breast reconstruction

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
