Los procedimientos reconstructivos en cabeza y cuello son todo un desafío debido a que son áreas expuestas, con gran movimiento, y desempeñan funciones esenciales de la vida como el habla, la alimentación y la respiración. El colgajo supraclavicular es un colgajo locorregional, fasciocutáneo, fino, axial a la arteria supraclavicular, versátil, con baja morbilidad, que se usa ampliamente para cubrir defectos en cuello y sector inferior de la cara ya que proporciona tejido similar al de estas regiones, y técnicamente rápido y sencillo.Se puede usar en asociación con otros colgajos para reconstrucciones complejas. Es un colgajo infrautilizado que es una buena alternativa frente a los colgajos tradicionales musculares regionales y libres. Las principales indicaciones son secuelas de quemaduras como las contracturas esternomentonianas, defectos oncológicos ya sea piel o mucosa oral, faringostomas y fístulas traqueocutáneas. Se mencionan 3 casos clínicos en los cuales se llevó a cabo un colgajo supraclavicular en el Hospital Pasteur, Montevideo, Uruguay.

Reconstructive head and neck procedures are challenging because they are exposed areas, are highly mobile, and perform essential life functions such as speaking, eating, and breathing. The supraclavicular flap is a locoregional, fasciocutaneous, thin flap, axial to the supraclavicular artery, versatile, with low morbidity, which is widely used to cover defects in the neck and lower face since it provides tissue similar to that of these regions, and Technically fast and simple. It can be used in association with other flaps for complex reconstructions. It is an underutilized flap that is a good alternative to traditional regional and free muscle flaps. The main indications are sequelae of burns such as sternomental contractures, oncological defects in the skin or oral mucosa, pharyngostomies and tracheocutaneous fistulas. Three clinical cases are mentioned in which a supraclavicular flap was performed at the Pasteur Hospital, Montevideo, Uruguay

Objective: To investigate the efficacies of different forms of free radial collateral artery perforator flaps in repairing the defects after oral tumor surgeries. Methods: From May 2016 to March 2021, 28 patients (22 males, 6 females, aged 35-62 years) with oral tumors admitted by Hunan Cancer Hospital received the reconstructive surgeries with the free radial collateral artery perforator flaps after removal of oral tumors, including 24 cases of tongue cancer (11 cases of tongue marginal cancer, 9 cases of tongue belly cancer and 4 cases of tongue cancer involved in the floor of the mouth) and 4 cases of buccal and oral cancer. Four forms of radial collateral artery perforator flaps were used: single perforator flaps for 6 cases, double perforators flaps for 7 cases, flaps without perforator visualization for 10 cases and chimeric perforator myocutaneous flaps for 5 cases. The recipient vessels were the superior thyroid artery and superior thyroid vein, and if second concomitant vein available, it was anastomosed with internal jugular vein in end-to-side fashion. SPSS 20.0 statistical software was used to analyze the data. Results: The mean length of flaps was (9.7±0.4) cm, mean width (4.4±0.3) cm and mean thickness (1.1±0.4) cm. The mean length of the vascular pedicles was (7.1±0.6)cm (6.0-8.0 cm), the mean diameter of the radial accessory arteries was (1.1±0.3)mm (0.8-1.3 mm). Eleven cases(39.3%) had respectively one accompanying vein and 17 cases(60.7%) had respectively two accompanying veins, with the mean diameter of (1.1±0.3) mm (0.8-1.3 mm). All the 28 flaps survived, the donor and recipient wounds healed in one stage, the appearances of the flaps were satisfactory, only linear scars remained in the donor sites, and the upper arm functions were not significantly affected. Follow up for 12-43 months showed that the flaps were soft with partially mucosalization, the reconstructed tongue and buccal cavity were in good shape, and the swallowing and language functions were satisfactory. The swallowing and language functions were retained to the greatest extent in 3 cases with near total tongue resection, although the functions were still significantly affected. There was no local recurrence of the tumor during follow-up. One case had regional lymph node metastasis, and further lymph node dissection and comprehensive treatment were performed, with satisfactory outcomes. Conclusions: The vascular pedicle of the radial collateral artery perforator flap has a constant anatomy, which can be prepared in different forms to improve the safety of the operation and minimize the donor site damage. It is an ideal choice for the repair of small and medium-sized defects after oral tumor surgery.

Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

Objective: To investigate the anatomical classification of adductor magnus perforator flap and its application in head and neck reconstruction. Methods: From January 2017 to January 2020, Hunan Cancer Hospital treated 27 cases of oral tumor patients (15 cases of tongue cancer, 9 cases of gingival cancer and 3 cases of buccal cancer), including 24 males and 3 females, aged 31-56 years old. The course of disease was 1-12 months. Secondary soft tissue defects with the sizes of 5.0 cm × 3.5 cm to 11.0 cm × 8.0 cm were left after radical resection of the tumors, and were repaired with free adductor magnus perforator flaps. The flaps based on the origing locations of perforator vessels were divided into three categories: ① intramuscular perforator: vessel originated between the gracilis muscle and the adductor magnus or passed through a few adductor magnus muscles; ② adductor magnus middle layer perforator: vessel run between the deep and superficial layers of adductor magnus; ③ adductor magnus deep layer perforator: vessel run between the deep layer of adductor magnus and the semimembranous muscle. Descriptive analysis was used in this research. Results: Perforator vessels of adductor magnus were found in all cases, with a total of 62 perforator branches of adductor magnus. The anatomical classification of the perforator vessels was as follows: 12 branches for class ①, 31 branches for class ② and 19 branches for class ③. The vascular pedicles of the free adductor major perforator flaps included type ① for 3 cases, type ② for 16 cases and type ③ for 8 cases. All 27 flaps survived and the donor sites were closed directly. In 18 cases, the perforator arteries and the venae comitan were respectively anastomosed with the superior thyroid arteries and veins. In 9 cases, the pedicle arteries and the venae comitan were respectively anastomosed with the facial arteries and veins. Follow up for 12-40 months showed that the appearances of the flaps and the swallowing and language functions of patients were satisfactory, apart from linear scars were left in the donor sites with no significant affect on the functions of thigh. Local recurrence occurred in 3 cases and radical surgeries were performed again followed by repairs with pedicled pectoralis major myocutaneous flaps. Cervical lymph node metastasis occurred in 2 cases and cervical lymph node dissection was performed again. Conclusions: The adductor magnus perforator flap has soft texture, constant perforator vessel anatomy, flexible donor location and harvesting forms, and less damage to the donor site. It is an ideal choice for postoperative reconstruction in head and neck tumors.

Se conocen varios colgajos locales basados en la arteria facial al momento de reconstruir unidades estéticas faciales. Levantar estos colgajos basados en las ramas perforantes de la arteria facial, los hace más finos, móviles, fiables, y adaptables, y la posibilidad de realizarlos en un solo tiempo quirúrgico. El propósito de este estudio es demostrar nuestra experiencia con el colgajo perforante de la arteria facial en reconstrucciones faciales de defectos hasta tamaño de 5x4cm, utilizando su pedículo superior o su pedículo inferior. Método. Realizamos un estudio longitudinal retrospectivo con 15 pacientes de ambos sexos, con edades comprendidas entre 40 a 60 años, a quienes se realizó el colgajo perforante facial en un solo tiempo quirúrgico. Los defectos faciales tratados fueron de tamaño pequeño a mediano, localizados en subunidades de la mejilla, nariz, pliegue nasolabial, labios superior e inferior. Resultados. De los 15 pacientes de nuestro estudio, 13 evolucionaron sin complicaciones (84.6%); 1 paciente concurrió con leve dehiscencia de herida (7.7%) y 1 paciente al que se le realizó un colgajo de 5x4cm concurrió con una mínima necrosis en la parte distal del colgajo (7.7%). Estas complicaciones fueron leves y con resolución ambulatoria, sin requerir otro tiempo quirúrgico. Conclusiones: Gracias a su libertad de movimiento, este colgajo nos permite reconstruir varias unidades estéticas, y por su delgado espesor, mínimas complicaciones y una cicatriz de la zona dadora que se camufla en el surco nasogeniano, los resultados tanto funcionales como estéticos son superiores comparados con los tradicionales colgajos locales miocutáneos nasolabiales.

Several local flaps based on the facial artery are well known when reconstructing facial aesthetic units. Making these flaps based on the perforating branches of the facial artery makes them thinner, more mobile, reliable, and adaptable, and the possibility of performing them in a single surgical time. The purpose of this study is to demonstrate our experience with the perforating vessel of the facial artery flap, in facial reconstructions of defects up to a size of 5x4 cm, using its upper or lower pedicle. Method. We carried out a retrospective longitudinal study with 15 patients of both sexes, aged between 40 and 60 years, who underwent the facial artery perforator flap in a single surgical time. The facial defects treated were small to medium in size, located in subunits of the cheek, nose, nasolabial fold, upper and lower lips. Results. The complications that we obtained when doing this flap were hematoma, partial dehiscence of the suture and slight venous congestion. All of these were mild and with outpatient resolution, without requiring another surgical time. Conclusions. Due to its freedom of movement, this flap allows us to reconstruct several aesthetic units, and due to its thin thickness and with minimal complications, both functional and aesthetic results are superior compared to traditional nasolabial myocutaneous flaps.

Abstract Objective The objective of the present study was to prospectively compare the sural and propeller flaps for soft-tissues coverage of the lower extremity. The following variables were evaluated: incidence of complete or partial flap loss and donor area morbidity (primary closure versus skin graft). Methods Prospective and randomized analysis of data collected from all patients presenting with soft tissue defects of the lower third of the leg and heel treated with reverse sural or propeller flaps. Results Twenty-four patients aged between 4 and 60 years old were evaluated between 2011 and 2017. Complete coverage was obtained in 22 of the 24 patients (91.6%). Two flaps failed (8.4%). The sural flap, being the most popular option, continues to represent a safe and versatile alternative for skin defects of the lower third of the leg and heel region. Likewise, the propeller flap was a comparable option to treat these challenging defects. Conclusion Sural and propeller flaps are good options for soft tissues coverage of the lower extremity, with low complication rates (partial or total flap loss).

Resumo Objetivo O objetivo do presente estudo foi comparar prospectivamente os retalhos sural e propeller para cobertura de partes moles da extremidade inferior. Foram avaliadas as seguintes variáveis: incidência de perda total ou parcial do retalho e morbidade da área doadora (fechamento primário versus enxerto de pele). Métodos Análise prospectiva e randomizada de dados coletados de todos os pacientes apresentando defeitos em tecidos moles da extremidade distal da perna e do retropé submetidos aos retalhos em questão. Resultados Foram avaliados 24 pacientes com idades entre 4 e 60 anos, entre 2011 e 2017. Cobertura completa foi obtida em 22 dos 24 pacientes (91,6%) e observamos falha em 2 retalhos (8,4%). O retalho sural, sendo a opção mais popular, continua a representar uma alternativa segura e versátil para defeitos cutâneos do terço distal da perna e da região do calcanhar. O retalho propeller, da mesma maneira, mostrou-se uma opção comparável para o tratamento destas lesões desafiadoras. Conclusão Os retalhos sural e propeller são boas opções para a cobertura de partes moles da extremidade inferior, demostrando baixas taxas de complicações como perda parcial ou total do retalho.

Materiales y Método: Disección anatómica con descripción vascular y dinámica de la vaina anterior de los rectos. Posterior aplicación de la técnica en pacientes con hernias gigantes de la línea media. Seguimiento clínico de recidiva y complicaciones locales como sistémicas. Resultados: 8 pacientes fueron seleccionados. La edad promedio fue de 58,6 años y el tamaño del defecto hemiario 19,6 cm. En todos los pacientes se pudo aplicar la técnica sin inconvenientes. Sólo 1 paciente presentó una complicación local (dehiscencia y necrosis parcial del colgajo cutáneo) que se manejó con resección y reavance sin incidentes. No se describen complicaciones sistémicas ni mortalidad. Discusión: Las hernias abdominales gigantes y con pérdida a derecho de domicilio son un desafío quirúrgico. Se han desarrollado importantes avances con abordajes quirúrgicos innovadores. Nuevos materiales biológicos y sintéticos se han convertido en una parte integral del arsenal quirúrgico, sin embargo, involucran muchas veces asumir grandes costos y complicaciones propias a los materiales utilizados, además, de no cumplir con la adaptación dinámica adecuada de la pared requerida. Conclusión: Esta modificación técnica es segura, útil y accesible para los pacientes con eventraciones gigantes. La tasa de complicaciones es baja y está dada principalmente por problemas relacionados al sufrimiento de los colgajos cutáneos.

Aim: To demonstrate the anatomy and application of the anterior rectus sheet in the repair of giant abdominal wall hernias through a classic component surgery plus a turn over flap. Materials and Method: Anatomic dissection with vascular and dynamic description of the anterior rectus sheet. Posterior application of the technique in patients with giant abdominal wall hernias. Clinical follow up of recurrence, local and systemic complications. Results: 8 patients were selected. The average age was 58.6 years old and the abdominal wall defect 19.6 cm wide. The technique could be applied in every patient without inconveniences. Only 1 patient had a complication (dehiscence and partial skin flap necrosis) that was successfully treated with resection and readvancement. No systemic complications nor mortality was described. Discussion: Giant abdominal wall hernias are a surgical challenge. Great and innovative advances have been made. New biological and synthetic materials have been developed, nevertheless they frequently involve great costs and complications related to them. Also, they do not adapt adequately to the dynamic required for the abdominal wall. Conclusion: This technical modification is useful, safe and accessible for the patients who present giant wall hernias. The complication rate is low and it's principally given from problems related to skin flap blood flow.

RESUMO Objetivo: analisar a experiência terapêutica inicial do transplante de linfonodos vascularizados em pacientes portadoras de linfedema de membros superiores secundário ao tratamento do câncer de mama e verificar se o posicionamento do transplante influencia o resultado cirúrgico. Métodos: ensaio prospectivo, comparativo, de duas modalidades terapêuticas em 24 pacientes portadoras de linfedema de membro superior após tratamento de câncer mamário, classificados como graus 2 e 3, segundo a Sociedade Internacional de Linfedema. Os dois tipos de procedimentos realizados foram: 1) reconstrução total da mama com retalho de perfurante da artéria epigástrica inferior (DIEP- deep inferior epigastric perforator flap) associado ao retalho linfonodal, em pacientes sem reconstrução mamária prévia ou com histórico de perda da reconstrução (posicionamento axilar); 2) retalho linfonodal inguinal isolado foi realizado em pacientes com reconstrução mamária finalizada ou sem o desejo de realizar a reconstrução da mama (posicionamento no punho). Resultados: a porcentagem de redução do volume do membro afetado foi de 20,1% (p=0,0370). O número de episódios infecciosos (celulites) também sofreu redução significativa, de 41% no período pré-operatório para 12,5% no pós-operatório (p=0,004). Não foram observadas diferenças entre os grupos proximal e distal. Conclusão: o transplante de linfonodos afetou positivamente a evolução pós-operatória de pacientes portadoras de linfedema secundário ao câncer de mama. Não foram observadas diferenças em relação ao posicionamento do retalho.

ABSTRACT Objective: to evaluate the initial therapeutic experience of transplantation of vascularized lymph nodes in patients with lymphedema of the upper limbs secondary to the treatment of breast cancer, and to verify if the positioning of the transplant influences the surgical result. Methods: we conducted a prospective, comparative test of two therapeutic modalities, with 24 patients with lymphedema of the upper limb after breast cancer treatment, classified as grades 2 and 3, according to the International Lymphedema Society. The two types of procedures performed were: 1) total breast reconstruction with - deep inferior epigastric perforator (DIEP) flap associated with lymph node flap, in patients with no previous breast reconstruction or loss of previous reconstruction (axillary positioning); 2) isolated inguinal lymph node flap performed in patients with completed breast reconstruction or without the desire to perform the breast reconstruction (wrist positioning). Results: the reduction percentage of the affected limb volume was 20.1% (p=0.0370). The number of infectious episodes (cellulites) also decreased significantly, from 41% in the preoperative period to 12.5% in the postoperative one (p=0.004). There were no differences between the proximal and distal groups. Conclusion: the transplantation of lymph nodes positively affected the postoperative evolution of patients with lymphedema secondary to breast cancer. We observed no differences in relation to flap positioning.

Abstract: A 37-year-old man complained of a refractory posterior malleolar ulceration on his left ankle. He was diagnosed with Werner syndrome according to the progeroid clinical features and genetic testing. To approach the ulceration, a free flow-through right anterolateral thigh perforator flap with anterolateral thigh cutaneous nerve was harvested. One year later, he was readmitted due to a new ulceration on his right ankle. We harvested the left anterolateral thigh perforator flap with anterolateral thigh cutaneous nerve to reconstruct the defect. After one more year of follow-up, there was no recurrence of ulcers, and the sensation of the flap recovered partially after 6 months. We conclude that free flow-through anterolateral thigh perforator flap is a feasible choice for the repair of foot ulcers in Werner syndrome.

Introducción. La reconstrucción mamaria sigue siendo hoy en día un verdadero desafío para la cirugía reparadora, que tiene como objetivo principal recuperar la imagen corporal y la calidad de vida de estos pacientes. Para lograr este cometido se cuenta con un amplio arsenal terapéutico. La reconstrucción con implantes es la forma más común de reconstrucción en el mundo. Sin embargo, las técnicas con tejidos autólogos han ganado terreno en los últimos años por su mejor calidad reconstructiva y durabilidad en el tiempo. Material y método. El colgajo DIEP consiste en un colgajo libre, compuesto por piel y tejido celular subcutáneo de la región abdominal inferior, basado en perforantes de la arteria epigástrica inferior profunda. Brinda buenos resultados reconstructivos, sin sacrifi cio funcional de la pared abdominal. El objetivo del trabajo es resaltar algunas de las características más relevantes de esta técnica y la experiencia de nuestro servicio en su utilización para la reconstrucción mamaria. Resultados y discusión. La experiencia del servicio con la utilización de este colgajo ha sido satisfactoria, con buenos resultados, bajas complicaciones y aceptación por parte de las pacientes. Conclusiones. Si bien se trata de un colgajo que requiere una técnica microquirúrgica, con una importante curva de aprendizaje, logra devolver una mama con características similares a la contralateral en forma, volumen y textura, con el benefi cio estético del contorneado corporal abdominal y sin las complicaciones del uso del material protésico, considerándose hoy en día como una herramienta más a tener en cuenta para la reconstrucción mamaria.

Background: Breast reconstruction remains as a real challenge for restorative surgery today, with the main objective of recovering the body image and the quality of life of these patients. To achieve this, there is a broad therapeutic arsenal. Reconstruction with implants is the most common form of reconstruction in the world; however, autologous tissue techniques have gained ground in recent years for their improved reconstructive quality and durability over time. Material and Method:The DIEP fl ap is a free fl ap, composed of skin and subcutaneous cellular tissue of the lower abdominal region, based on perforators of the deep inferior epigastric artery, providing good reconstructive results, without functional sacrifi ce of the abdominal wall. The objective of this work is to highlight some of the most relevant characteristics of this technique and the experience of our service in its use for breast reconstruction. Results and Discussion: The experience of the Service with the use of this fl ap has been satisfactory, with good results, low complications and acceptance by the patients. Conclusions: Although it is a fl ap that requires a microsurgical technique, with an important learning curve, it manages to return a breast with similar characteristics to the contralateral in shape, volume and texture, with the esthetic benefi t of abdominal body contouring and without complications of the use of prosthetic material, being considered nowadays as one more tool to take into account for the reconstruction mammary.

Objetivo: Analizar nuestra experiencia en la reconstrucción mamaria terciaria tras el fracaso de procedimientos basados en implantes. Material y métodos: Entre 2005 y 2014, los autores (BH y CA) realizaron reconstrucción mamaria terciaria en 17 casos utilizando el colgajo de perforantes de arteria epigástrica inferior profunda (DIEP). Se revisaron en forma retrospectiva las fichas clínicas de dichas pacientes, registrando edad, comorbilidades, índice de masa corporal (IMC), presencia de cicatrices abdominales, historia de radioterapia y quimioterapia. Asimismo, se registraron los detalles de las cirugías realizadas, tanto de la reconstrucción con implante como de la reconstrucción terciaria. Resultados: Las complicaciones más frecuentes que motivaron el cambio de estrategia reconstructiva fueron: contractura capsular, rotura, exposición/infección del implante, dolor crónico y el fracaso de la expansión de la piel. En la reconstrucción terciaria se utilizó el colgajo DIEP en todos los casos, presentando pérdida parcial del colgajo un solo caso, sin pérdidas totales del mismo. Conclusiones: Las opciones actuales en reconstrucción terciaria con tejido autógeno incluyen principalmente colgajos perforantes, siendo el colgajo DIEP el más utilizado. De acuerdo con los resultados de esta serie y lo reflejado en la literatura, creemos que la reconstrucción terciaria es un procedimiento seguro, con una tasa de complicaciones similar a las de reconstrucción primaria y secundaria, y que otorga una serie de beneficios a las pacientes afectadas.

Objective: Analyze our experience on tertiary breast reconstruction after failed implant-based procedures. Methods: Between 2005 and 2014, the authors (BH and CA) performed tertiary breast reconstruction with the deep inferior epigastric artery perforator flap (DIEP) flap in 17 cases. The medical charts of these patients were retrospectively reviewed, registering age at tertiary reconstruction, comorbidities, body mass index (BMI), presence of abdominal scars and history of radiotherapy and chemotherapy. Likewise, details from surgeries were also gathered, both form the implant-based procedures and tertiary autologous reconstruction. Results: Complications motivating the change of reconstructive strategy included capsular contracture, implant rupture, implant exposure/infection, chronic pain and failure of skin expansion. Regarding tertiary reconstruction, the DIEP flap was used in all cases with one partial flap loss and no total failures. Conclusions: Current options for autologous tertiary reconstruction include mainly perforator flaps with the DIEP being by far the most utilized. Additionally, tertiary reconstruction is a safe procedure, with a rate of complications similar to that of primary and secondary free flap breast reconstruction.

Introducción: El cáncer de mama es la neoplasia que afecta en forma más frecuente a las mujeres en el mundo. Posterior a una mastectomía, el uso de tejidos autógenos para la reconstrucción mamaria tiene mejores resultados a largo plazo. La utilización de colgajos libres obtenidos del abdomen se ha planteado como una alternativa adecuada. Objetivos: Se reportan una serie de casos con el uso de colgajos libres de vasos perforantes de la arteria epigástrica inferior profunda (DIEP) y vasos epigástricos inferiores superficiales (SIEA) en la reconstrucción de mama. Pacientes y método: Describimos 21 casos de reconstrucción mamaria utilizando el colgajo DIEP y 3 casos de colgajo SIEA en la Clínica Las Condes (CLC) entre el 2007 y 2015. Resultados: De un total de 24 pacientes con un rango de edad de entre 48 y 60 años, 18 de ellas fueron sometidas a reconstrucción unilateral, 3 a reconstrucción bilateral con DIEP, y 3 fueron sometidas a reconstrucción unilateral con colgajo SIEA. El tiempo operatorio promedio fue de 6,5 h y el tiempo de hospitalización, de 6 días. En una reconstrucción bilateral hubo pérdida del colgajo izquierdo por trombosis venosa, la cual se sometió a una segunda reconstrucción con colgajo libre. Discusión: En nuestra experiencia en la CLC, la reconstrucción mamaria con colgajos libres perforantes de la zona inferior del abdomen tiene una baja morbilidad. La literatura avala esta técnica como una alternativa válida en pacientes seleccionadas.

Introduction: Breast cancer is the most frequent neoplasia affecting women worldwide. After mastectomy for breast cancer, autologous tissue breast reconstruction offers better long-term results. The use of abdominal free flaps has shown to be an adequate option. Aim: We report a series of cases of deep inferior epigastric perforator flap (DIEP flap) and superficial inferior epigastric artery flap reconstructions. Patients and methods: We describe 21 patients with breast reconstruction using DIEP flap and 3 cases of SIEA flap in CLC between 2007 and 2012. Results: 24 patients underwent the procedure with an age range of 48 to 60 years; 18 patients underwent a unilateral reconstruction and 3 patients bilateral reconstructions with DIEP flaps; 3 patients underwent unilateral breast reconstruction with SIEA flap. Mean operative time was 6,5 h and mean hospitalization was 6 days. In one bilateral reconstruction the left flap was lost, which required a second free flap reconstruction. Discussion: In our experience, microvascular breast reconstruction using perforator flaps has a low morbidity. As described in the literature, this is a valid alternative in selected patients.

As deformidades da parede torácica apresentam uma ampla variedade de possibilidades em sua reconstrução. Nas últimas décadas, o tratamento cirúrgico de afecções que comprometem a parede torácica tem progredido muito, sendo que o método de reconstrução dependerá do tipo da lesão e do objetivo da ressecção prévia. O uso de retalho fasciocutâneo de perfurante da artéria mamária interna tem sido uma boa opção para reconstrução de defeitos de tamanho pequeno a médio da parede torácica, com bons resultados e mínima morbidade ao sítio doador. O presente trabalho apresenta o uso do retalho de perfurante de artéria mamária interna na reconstrução torácica de um paciente com recidiva tumoral após duas ressecções do mesmo tumor(AU)

Chest wall deformities allow a wide variety of approaches to their reconstruction. In recent decades the surgical treatment of diseases that compromise the chest wall has progressed a lot, and the reconstruction method will depend on the type of injury and the aim of prior resection. The use of internal mammary artery fasciocutaneous perforator flap is a good option for reconstruction of small defects in the middle of the chest wall with good results and minimal donor-site morbidity. This paper presents the use of internal mammary artery perforator flap in chest reconstruction of a patient with tumor recurrence after two resections of the same tumor(AU)

Introducción. El colgajo dorsal ancho es un método efectivo para reconstrucción mamaria tanto en forma inmediata como tardía. Diversas variantes pueden realizarse en cuanto al diseño y elevación del colgajo dorsal. El propósito del siguiente trabajo es presentar nuestra experiencia con la utilización del colgajo dorsal y sus variantes. Métodos. Se presenta un estudio retrospectivo de 87 casos en los que se realizó reconstrucción mamaria con colgajo dorsal en el período comprendido entre abril de 2011 y diciembre de 2013. De los casos presentados, en 75 (86%) la reconstrucción mamaria fue inmediata. En 45 casos (51%) se utilizó el colgajo dorsal miocutáneo reducido, en 14 (16%) se utilizó el colgajo dorsal miocutáneo con expansor tisular, en 14 (16%) se utilizó colgajo dorsal miocutáneo extendido, en 4 (5%) se utilizó el colgajo dorsal perforante, en 7 (8%) se utilizó colgajo dorsal ancho libre contralateral y en 3 (4%) se utilizó colgajo dorsal asociado a otro colgajo libre. Resultados. Se realizaron 87 casos en 81 pacientes (en 6 pacientes de manera bilateral). La vitalidad del colgajo fue completa en 85 casos. La complicación mayor, sufrimiento distal del colgajo, se presentó en 2 casos y en ambos el colgajo fue extendido. Complicaciones menores: seroma en 30 casos (34 %), celulitis en 6 casos (7%), dehiscencia de la cicatriz en 3 casos (4%) y secuela cicatriz hipertrófi ca en 14 casos (16%). Conclusiones. El colgajo dorsal ancho miocutáneo permite un aporte de tejido vascularizado en casos de défi cit cutáneo en la región anterior de tórax. Por otro lado, permite una combinación de variantes adecuada a cada caso.

Introduction. The wide dorsal fl ap is an eff ective method for breast reconstruction immediately so as late. Diff erent variants can be made in the design and dorsal fl ap elevation. The purpose of this paper is to present our experience with the use of the dorsal fl ap and its variants. Methods. A retrospective study of 87 cases in which breast reconstruction was performed with dorsal fl ap in the period between April 2011 and December 2013. Of the cases presented, in 75 (86%) was immediate breast reconstruction is presented. The small dorsal myocutaneous fl ap in 14 (16%) used the dorsal myocutaneous fl ap tissue expander was used in 45 cases (51%), in 14 (16%) was used fl ap extended dorsal myocutaneous in 4 (5%) perforating dorsal fl ap was used in 7 (8%) it was used fl ap contralateral dorsal clear width and 3 (4%) dorsal fl ap associated with another free fl ap was used. Results. 87 cases were performed in 81 patients (6 patients bilaterally). The vitality of the fl ap was complete in 85 cases. The major complication, suff ering distal fl ap, was presented in 2 cases and both the fl ap was extended. Minor complications: seroma in 30 cases (34%), cellulitis in 6 cases (7%), scar dehiscence in 3 cases (4%) and hipertrofi c scars in 14 cases (16%). Conclusions. The latissimus dorsi myocutaneous fl ap allows a contribution of vascularized tissue in cases of cutaneous defect in the anterior chest. On the other hand, allows a combination of suitable variants for each case.

INTRODUÇÃO: Uma grande evolução ocorreu desde o primeiro registro de transferência de tecido abdominal para reconstrução de mama pós-mastectomia. O retalho baseado em vasos perfurantes da artéria epigástrica inferior (DIEAP flap) apresenta-se com um dos mais recentes desenvolvimentos da área. MÉTODOS: Este artigo analisa fatos importantes na área de reconstrução autóloga da mama utilizando retalhos baseados no abdome, com ênfase nos retalhos microcirúrgicos vascularizados por pedículos perfurantes. RESULTADOS: Na experiência inicial do serviço, pudemos verificar que o retalho se comportou de acordo com a experiência relatada na literatura. CONCLUSÃO: O DIEAP flap apresenta uma possibilidade maior de escultura e ganho volumétrico na mama reconstruída, além de evolução pós-operatória muito positiva.

INTRODUCTION: Great advances have been reported since the first abdominal tissue transfer carried out for breast reconstruction after a mastectomy. The deep inferior epigastric artery perforator (DIEAP) flap is one of the most recent advances in this area. METHODS: In this article, we evaluate the important aspects in the field of autologous breast reconstruction with abdominal-based flaps, with emphasis on microsurgical flaps vascularized by perforating pedicles. RESULTS: During the initial experience of this procedure, we were able to verify that the flap behaved according to what was reported in the literature. CONCLUSION: The DIEAP flap provides a great degree of sculpting and volumetric gain to the reconstructed breast besides allowing a positive postoperative course for the patient.

La mama puede verse afectada por diferentes causas; las más frecuentes de ellas son las lesiones por quemaduras. Este tipo de afecciones producen en general secuelas cicatrizales que van a interferir en el desarrollo normal de la mama y en su apariencia estética. La reconstrucción mamaria es uno de los grandes retos de la cirugía plástica. Las técnicas han evolucionado en las últimas décadas y cada una de ellas debe ser ajustada a cada paciente de acuerdo con la reconstrucción requerida en cada caso individual. Presentamos un caso problema de una secuela grave de quemadura en la región mamaria lateral derecha, en el cual empleamos en su reconstrucción el colgajo submamario de base lateral, irrigado por las perforantes intercostales que emergen en la línea media axilar. Es un colgajo de fácil reproducción, con una seguridad vascular estable y con excelentes resultados estéticos tanto en la zona dadora como receptora.
