Uso tópico de sevoflurano en heridas complejas de miembro inferior / Topical use of sevoflurane in complex lower limb wounds

El dolor crónico asociado a heridas de larga evolución en miembros inferiores constituye una situación de conflicto con características angustiantes que compromete seriamente la calidad de vida e interfiere en el proceso de reparación tisular, estableciendo un cuadro propio en el cual la herida se transforma en un componente más de esta compleja condición y no el motivo en sí de la consulta. Dadas las limitaciones y efectos negativos de las terapias usuales para el alivio del dolor crónico en heridas, se establece una apertura a nuevas propuestas adyuvantes. Motivo de ello es el propósito del presente trabajo, a través del uso de sevoflurano tópico para evaluar el incremento de la analgesia en una población con úlceras en miembro inferior de diverso origen etiológico.

Manejo de tejidos blandos en trauma de miembros inferiores: a propósito de un caso / Soft tissue management in lower limb trauma: about a case

Los miembros inferiores están sujetos frecuentemente a traumas que ocasionan daño de estructuras vitales y que pueden dejar secuelas funcionales y estéticas en las personas. Las lesiones de tejidos blandos son las que asientan en la piel, tejido celular subcutáneo, aponeurosis, músculos, vasos y nervios. Del manejo oportuno y adecuado de las lesiones que se presenten posteriores a un trauma de tejidos blandos dependerá el resultado, el tiempo de recuperación, costos de hospitalización y sobre todo la preservación de las funciones de locomoción y sostén del miembro afectado

The lower limbs are frequently exposed to traumas that cause vital structures damage and can leave functional and aesthetic sequelae in patients. Soft tissue lesions are those that affect the skin, subcutaneous cellular tissue, fascia, muscles, vessels, and nerves. The result, recovery time, hospitalization costs and, above all, the preservation of the locomotion and support functions of the affected limb will depend on the timely and adequate management of injuries that occur after a soft tissue trauma.

Síndrome de Stewart-Treves no membro inferior com apresentação exuberante: relato de caso / Profuse Stewart-Treves syndrome in the right leg: a case report

A Síndrome de Stewart-Treves é uma rara condição onde um angiossarcoma se desenvolve sobre área de linfedema crônico. Afeta mais frequentemente os membros superiores e representa 5% dos casos de angiossarcoma. Apesar de ser mais comum em mulheres submetidas a mastectomia radical e esvaziamento axilar por neoplasia de mama, pode ocorrer a partir de linfedema de outras etiologias. Clinicamente as lesões são caracterizadas por nódulos únicos ou múltiplos de cor avermelhada ou azulada no estágio inicial e, em estágio avançado, podem evoluir para massas hemorrágicas e até gangrena. O prognóstico é ruim e a conduta cirúrgica com excisão ampla ou amputação oferecem uma maior chance de sobrevida. Relata-se um caso de Síndrome de Stewart-Treves na perna direita, apresentando-se de forma exuberante e com acometimento de linfonodos pélvicos e abdominais.

Stewart-Treves syndrome is a rare condition characterized by the development of an angiosarcoma at sites of chronic lymphedema. It most often affects the upper limbs and accounts for 5% of cases of angiosarcoma. Although the syndrome is more common in women undergoing radical mastectomy and axillary dissection for breast cancer, it may result from lymphedema of other etiologies. Clinically, the lesions are characterized by single or multiple bluish-red nodules in the early stage and may progress to hemorrhagic masses and even gangrene in advanced stages. The prognosis is poor, and surgical management with wide excision or amputation offers a greater chance of survival. We report a case of profuse Stewart-Treves syndrome in the right leg, with involvement of pelvic and abdominal lymph nodes.

Presión intracompartimental y signos clínicos en pacientes con fracturas diafisarias en miembros inferiores ingresados en el IAHULA / Intracompartimental pressure and clinical Signs in patiens with diaphyseal fractures of the lower limbs admitted at IAHULA hospital

Las fracturas diafisarias del fémur y la tibia son las lesiones traumáticas más comunes a nivel mundial, afectan principalmente a la población joven y económicamente activa como consecuencia de traumatismos de alta energía, en su mayoría accidentes viales. Las complicaciones de estas lesiones han sido ampliamente descritas y las implicaciones médico-legales son importantes cuando estas no son detectadas a tiempo. Por lo que resulta relevante estudiar como se comportan las presiones intracompartimentales en las fracturas cerradas y su evolución en el tiempo, así como las manifestaciones clínicas durante las primeras 12 horas de evolución. Se realizó un estudio observacional transversal en 65 pacientes con fracturas cerradas diafisarias de fémur y tibia, evaluando las cifras de presión intracompartimental y las variables clínicas al momento de su ingreso y a las 12 horas de evolución intrahospitalaria. Encontramos que el compartimento más afectado es el anterior con un promedio de presión al ingreso de 22,26±6,90 mmHg. Asimismo, se demostró una relación directa entre el mecanismo y energía del trauma con respecto a las cifras de presión intracompartimental. Los resultados del estudio demostraron que el parámetro clínico más importante fue el dolor, el cual está relacionado con la energía del trauma(AU)

Diaphyseal fractures of the femur and tibia are the most common traumatic injuries worldwide, mainly affecting the young and economically active population as a consequence of high-energy trauma, mostly traffic related accidents. The complications of these injuries have been widely described and the legal implications are important when they are not detected early enough. Therefore, its relevant to study how intracompartmental pressures behave in closed fractures and their evolution, as well as the clinical manifestations during the first 12 hours. A cross-sectional observational study was made. 65 patients with closed diaphyseal fractures of the femur and tibia were included. The intracompartmental pressure numbers and the clinical variables at the time of admission and at 12 hours of in-hospital evolution were evaluated. As results, the most affected compartment is the anterior one with an average pressure at admission of 22.26 ± 6.90 mmHg. A direct relationship between the mechanism and energy of the trauma was also demonstrated with respect to the intracompartmental pressure levels reported. The most important clinical parameter was the pain, related to the energy of the trauma(AU)

Cierre progresivo de heridas en pacientes con pie diabético / Progressive suture in diabetic foot patients with difficult healing

Resumen Introducción: Los pacientes diabéticos insulino requirientes con heridas del pie, producto de amputaciones con exposición de huesos, cartílagos o tendones, son de difícil manejo por el déficit de irrigación distal. Alternativa de tratamiento a los colgajos pediculados o microquirúrgicos es el cierre progresivo de las heridas. Objetivo: Reportar la técnica de cierre progresivo de heridas de pie en pacientes diabéticos insulino requirientes. Materiales y Método: Con esta técnica se operó a 15 pacientes diabéticos insulino requirientes que, después de amputación, presentaron heridas del pie con exposición de huesos, cartílagos y tendones. Lesiones de talón: 4, lesiones de antepie: 5 y lesiones plantares: 6. Las edades fluctuaron entre 45 y 70 años. Fueron 11 hombres y 4 mujeres operados entre 2014 y 2019. En ambos bordes de la herida se instaló dos placas de Ventrofil® unidas por sutura en U transversa y se tensó cada 3 días hasta obtener cicatrización. Resultados: 14 pacientes obtuvieron cicatrización en un plazo de entre 15 y 21 días y sólo uno presentó sufrimiento de los bordes de la herida por afrontamiento muy seguido. El seguimiento fue de tres meses sin recidiva de las heridas. Discusión: En pacientes diabéticos las heridas, producto de amputaciones y con exposición de huesos, cartílagos y tendones, son de muy difícil tratamiento debido el déficit de irrigación distal. En estas condiciones el uso de complejos colgajos locales o microquirúrgicos es de alto riesgo dada la posibilidad de necrosis. En esta situación, el cierre progresivo con sutura de Ventrofil® es una alternativa viable, segura, reproducible y con buenos resultados. Conclusión: Es un procedimiento rápido, seguro y reproducible.

Introduction: The closure of wounds in diabetic foot patients, after amputation with esposure of bones, is difficult because of lack of blood supply to this area. The progressive suture with Ventrofil® is a good alternative. Aim: Report the technique of progressive closure of foot wounds in insulin-requiring diabetic patients. Materials and Method: 15 patients with diabetic foot were operated on in the Hospital del Salvador, between 2014 and 2019.The ages were among 45 and 70 years. 11 men and 4 women. In those patients two plaques of Ventrofil® were positioned in both borders of the wound an tied through a horizontal suture.This suture was tensioned every 3 days until get the complete wound healing. Results: 14 patients healed very well and in just only one patient there was suffering of the edges of the wound. The follow up was of 3 months without relapse. Discussion: In patients with diabetic foot with wounds after amputation the closure is difficult because of lack of adecuate blood supply. In these case the progressive suture with plaques of Ventrofil® is a good alternative to a more complex flaps like microsurgicals ones. Conclusion: This technique is sure, easy to perfom and safe.

Reconstrucción de la fosa poplítea con colgajo fasciocutáneo de la arteria safena / Reconstruction of the popliteal fossa with fasciocutaneous flap of the saphenous artery

INTRODUCCIÓN. Los defectos de la fosa poplítea suponen un desafío reconstructivo para el cirujano plástico, dada la relación íntima de esta área con la articulación de la rodilla y la neurovasculatura vital subyacente. El propósito de éste informe fie compartir la experiencia en la utilización de un colgajo fasciocutaneode la arteria safena. CASO CLÍNICO. Paciente de 5 años de edad que sufrió quemadura térmica en miembros inferiores con dos años y medio de evolución, ameritó injertos, presentó contractura por tejido cicatricial en fosa poplítea, dificultó la deambulación y desarrollo neuro osteomuscular. Se realizó reconstrucción de la fosa poplítea con colgajo fasciocutáneo de la arteria safena. RESULTADOS. El colgajo fasciocutáneo de la arteria safena dio cobertura al defecto en fosa poplítea izquierda tras retiro del tejido cicatricial que producía contractura, limitaba la marcha y el desarrollo neuro osteo-muscular. Seis meses postquirúrgicos brindó cobertura cutánea definitiva y estable en el área crítica, que permitió la deambulación con movimientos de extensión y flexión de rodilla conservados. DISCUSIÓN. Este colgajo al igual que en otros estudios que respaldan su ejecución brindó excelentes resultados en defectos de partes blandas a nivel de la articulación de la rodilla. CONCLUSIÓN. El colgajo fasciocutáneo de la arteria safena demostró utilidad para la reconstrucción del defecto de la fosa poplítea, posibilitó una cobertura definitiva, funcional y estética, restableció los ángulos de movilidad y favoreció el desarrollo pondoestatural del paciente.

INTRODUCTION. Defects of the popliteal fossa pose a reconstructive challenge for the plastic surgeon, because of the intimate relation of this area with the knee joint and the near vital neurovasculature; the purpose of this report was to share the experience of using a fasciocutaneous flap of the saphenous artery. CLINICAL CASE. A 5 year old patient who suffered thermal burn in lower limbs with two and a half years of evolution, he nedeed grafts and presented tissue contracture because the scar in the popliteal fossa hindered ambulation and neuro-osteomuscular growth. Reconstruction of the popliteal fossa was made it with a fasciocutaneous flap of the saphenous artery. RESULTS. The fasciocutaneous flap of the saphenous artery covered the defect in the left popliteal fossa after removal of the scar tissue that caused contracture, limited to walk and growth. Six months after surgery the flap provided definitive and secure skin coverage in the critical area, which allowed to walk with preserved knee extension and flexion movements. DISCUSSION. This flap was useful for the recons-truction of the defect of the popliteal fossa and provided excellent results in soft tissue defects in this area of the knee joint. CONCLUSION. The fasciocutaneous flap of the saphenous artery proved useful for the reconstruction of the popliteal fossa defect, it permited a definitive, functional and esthetic coverage, reestablished the angles of mobility and helped with the patient growth

The immobility of lower limbs constituted the predominant risk factor (27.0 %), as long as pain, edema and tachycardia were the most frequent clinical manifestations (20.5 % in each one), and the left lower limb was the most affected (69.0 %). Conclusions: The venous thrombosis of lower limbs was presented as characteristic of the advanced ages of life, mainly in women, with a clinical pattern that indicated with high clarity its existence.

Técnica de infi ltración perineural en heridas complejas (PIT) / Perineural infiltration technique (PIT) in complex wounds

El dolor asociado a heridas complejas se erige como una gran barrera para la resolución de estas, debido a la complejidad de abordaje y a la imposibilidad de establecer un patrón de algoritmo por diversos factores y su carácter heterogéneo, así como por la presencia de manifestaciones múltiples asociadas. Este dolor provoca al paciente un daño no solo físico sino también psicosocial, porque la escasa respuesta a los tratamientos habituales, y si bien es sensible a la medicación con opiáceos, los resultados son insufi cientes a largo plazo en un significativo número de pacientes, en quienes provoca además efectos no deseables. Se establece en el presente trabajo la administración subcutánea de dextrosa 5% a través de una técnica de infiltración perineural para el tratamiento de la infl amación neurogénica responsable del mencionado padecimiento, en las terminaciones libres de los nervios sensitivos cutáneos. Para ello se decidió realizar un estudio descriptivo multicéntrico a partir de junio del 2016 hasta mayo del 2017 en 60 pacientes que presentaban dolor crónico en ulceras de miembro inferior de diferente etiología con antecedente de medicación analgésica previa con resultado parcial (no controlado) y que tuviera evolución de su dolor entre 3 meses y 4 años.

The pain associated with complex wounds is established as a great barrier for the irresolution, due to the complexity of the approach and the impossibility of establishing an algorithm pattern due to various factors and their heterogeneous nature, as well as the presence of associated multiple manifestations. . This pain causes not only physical but psychosocial damage to the patient, because of the poor response to the usual treatments, and although it is sensitive to medication with opiates, the results are insufficient in the long-term in a significant number of patients, in whom it also causes undesirable effects. The present work establishes the subcutaneous administration of 5% dextrose through a perineural infi ltration technique for the treatment of the neurogenic inflammation responsible for the afore mentioned condition, in the free terminations of the cutaneous sensory nerves. For this, it was decided to carry out a multicenter descriptive study from June 2016 to May 2017 in 60 patients who presented chronic pain in lower limb ulcers of different etiology with a history of previous analgesic medication with partial (uncontrolled) outcome and had evolution of your pain between 3 months and 4 years.

Nódulo proliferativo en nevus melanocítico congénito gigante / Proliferative nodule in giant congenital melanocytic nevus

El nevus melanocítico gigante es una entidad poco frecuente. En los primeros meses o años de vida, pueden aparecer nódulos dérmicos pequeños o grandes, muy pigmentados, que pueden crecer rápidamente o incluso ulcerarse. Esto obliga a realizar diagnóstico diferencial con el melanoma. Se presenta el caso de una paciente de 3 años de edad, con gran lesión pigmentada en pierna izquierda, con nódulos de rápido crecimiento, compatibles con nódulo proliferativo.

Giant melanocytic nevi are rare. In the fi rst few months or even years of life, they may develop small or large dermic nodules, very pigmented, with rapid growth o even ulcer formation. This forces the diff erential diagnosis with melanoma. We present a case of a 3 year old female patient, with a large pigmented lesion on the left leg, with nodules compatible with proliferative nodules.

Probabilidad de lesión de tren inferior e índice de grasa corporal en talleres deportivos universitarios / Probability of lower body injury and body fat index in university sports workshops

El objetivo es verificar si existe relación entre la probabilidad de lesión en extremidades del tren inferior y el índice de grasa corporal en estudiantes que participan de talleres deportivos en la Universidad Adventista de Chile. Participaron 66 alumnos entre las áreas deportivas voleibol, básquetbol, fútbol y hándbol por un método de muestreo censal. Todos los participantes de la investigación fueron evaluados por medio del instrumento "Y balance Test", para verificar si son propensos a sufrir una lesión de tren inferior y además se les realizó una evaluación antropométrica para conocer su índice de grasa corporal. Los resultados no encontraron correlación entre porcentaje de grasa y probabilidad de lesión, sin embargo, se encontró correlación entre probabilidad de lesión entre una pierna y otra

The objective is to verify if there is a relationship between the likelihood of limb injury in the lower body and the body fat index in students participating in sports workshops at the Adventist University of Chile. 66 students participated in sports areas such as volleyball, basketball, soccer and handball by a census sampling method. All the participants of the investigation were evaluated by means of the "Y balance Test" instrument, to verify if they are prone to suffer a lower train injury and also an anthropometric evaluation was done to know their body fat index. The results did not find correlation between fat percentage and injury probability, however, a correlation was found between the injury probability between one leg and the another

Cobertura de lesões em pé e terço inferior da perna com retalho fasciocutâneo reverso da panturrilha (Carriquiry) / Coverage of the lower third of the limb and foot injuries using reverse sural fasciocutaneous flap described by Carriquiry

Introdução: Lesões no terço distal dos membros inferiores, com exposição de ossos, articulações, tendões e vasos sanguíneos, não são passíveis do uso de enxertos de pele. Isto ocorre porque o leito vascular é exíguo e pela pobre granulação das feridas, podendo apenas ser corrigidas com retalhos musculares, miocutâneos, fasciocutâneos ou transferência microcirúrgica. Métodos: O retalho em seu limite inferior é demarcado a partir de 5 cm acima dos maléolos. Superiormente, é marcado num comprimento suficiente para cobertura total da lesão. Realizada incisão em demarcação prévia, e elevados pele e tecido subcutâneo juntamente com a fáscia muscular. O nervo sural é preservado em seu leito original. A elevação do retalho se dá até o ponto inferior marcado (o pedículo). Neste ponto, o retalho é transposto numa angulação suficiente para alcançar a lesão. Resultados: Oito casos foram operados utilizando o retalho descrito. Todos apresentavam exposição de ossos e tendões em região distal da perna, dorso do pé ou ambos, nos quais foram utilizados o retalho fasciocutâneo reverso da perna com a técnica proposta por Carriquiry. Os casos apresentaram resultados estético e funcional satisfatórios. Conclusão: O retalho utilizado se presta à correção de lesões do terço inferior da perna e do pé. É relativamente fácil de ser confeccionado, com bom suprimento vascular, e não há perda funcional do leito doador.

Introduction: Skin grafts are not effective to cover lesions in the distal third of the lower limbs that expose the bones, joints, tendons, and blood vessels due to a limited vascular bed and poor granulation of the wounds. These lesions can only be corrected with microsurgical transfer or muscle, myocutaneous, or fasciocutaneous flaps. Methods: The lower border of the flap was marked 5 cm above the malleolus. The upper border was marked after providing sufficient length for complete coverage of the lesion. The incision was performed at the marked upper border, and the skin and subcutaneous tissue were elevated together with muscle fascia. The sural nerve was preserved in its original bed. The flap was lifted to the marked lower border (the pedicle). At this point, the flap was transposed at a sufficient angle to cover the lesion. Results: Eight cases of surgery were conducted using the flap described above. All cases had exposed bones and tendons in the distal region of the limb, back of the foot, or both, in which the reverse sural fasciocutaneous flap with the technique proposed by Carriquiry was used. The cases showed satisfactory esthetic and functional results. Conclusion: The used flap can correct lesions of the lower third of the limbs and foot. It is relatively easy to make, with good vascular supply, and there is no functional loss of the donor area.

Vasculopatia livedoide tratada com rivaroxabana / Livedoid vasculopathy treated with rivaroxaban

A vasculopatia livedoide é uma doença rara caracterizada pela oclusão da microvasculatura da derme, originando lesões maculosas que, posteriormente, podem evoluir para úlceras e cicatrizes atróficas. Como um fenômeno vaso-oclusivo, o tratamento geralmente é realizado com antiplaquetários e fibrinolíticos. O presente relato descreve o caso de uma paciente refratária à terapia convencional, que obteve regressão da doença utilizando a rivaroxabana, um fármaco inibidor seletivo do fator Xa. (AU)

Livedoid vasculopathy is a rare disease characterized by occlusion of the dermis microvasculature, leading to spotted lesions that can later develop into ulcers and atrophic scars. As a vaso- occlusive phenomenon, treatment is usually performed with antiplatelet and fibrinolytic agents. The present report describes the case of a female patient refractory to conventional therapy who presented disease remission using rivaroxaban, a selective factor Xa inhibitor drug. (AU)

Amputación traumática de miembros inferiores / Traumatic Amputation of Lower Limbs

RESUMEN La amputación traumática completa se define como la separación total de un segmento del miembro del resto del cuerpo. El segmento cercenado algunas veces se puede reconectar, siempre que ambas partes de la extremidad hayan sido correctamente tratadas y se cumplan determinadas condiciones. Se presentan dos casos de amputación traumática de ambos miembros inferiores: el primero, una paciente femenina de 49 años de edad, debido a un accidente de trabajo y, el segundo, un paciente masculino de 39 años, víctima de un accidente en las vías férreas. Se expone la sintomatología presentada por ambos pacientes, su tratamiento quirúrgico y evolución(AU)

ABSTRACT Complete traumatic amputation is defined as the total separation of a limb segment from the rest of the body. The severed segment can sometimes be reconnected, provided that both parts of the limb have been correctly treated and certain conditions are met. Two cases of traumatic amputation of both lower limbs are presented: the first, a female patient of 49 years of age, due to an accident at work; and the second, a male patient of 39 years, victim of a railroad accident. The symptoms presented by both patients, their surgical treatment and evolution are exposed(AU)

Effect of cilostazol in experimental model of degloving injuries in rat limbs

Abstract Purpose: To evaluate the effect of the cilostazol on the evolution of partially avulsed flaps, using experimental model of cutaneous degloving in rat limbs. Methods: A controlled and randomized experimental study was carried out in which the blood flow and the percentage of flap necrosis were evaluated. We compared the study group, which received cilostazol, and the control group, which received enteral saline solution in the postoperative period. The blood flow in the flap was evaluated through Laser Doppler flowmetry, and a planimetry using the IMAGE J® software was employed for the calculation of the area of necrosis. Results: Enteral administration of cilostazol was associated with a higher mean blood flow in all regions of the flap, with a statistically significant difference in the proximal and middle regions (p<0.001) and a lower percentage of necrotic area in the flap (p<0.001). Conclusion: Postoperative enteral administration of cilostazol increased blood flow and decreased the total area of necrosis of avulsed cutaneous flaps of rat limbs.

Sericin and swimming on histomorphometric parameters of denervated plantar muscle in Wistar rats / Sericina e natação sobre parâmetros histomorfométricos de músculo plantar desnervado de ratos Wistar

Abstract Objective To analyze the combined effects of the silk protein sericin and swimming exercise on histomorphometry of the plantar muscle in Wistar rats. Methods Forty adult rats were randomly allocated into 5 groups comprising 8 animals each, as follows: Control, Injury, Sericin, Swim, and Swim plus Sericin. Three days after crushing of the sciatic nerve the rats in the Swim and Swim plus Sericin Groups were submitted to swimming exercise for 21 days. Rats were then euthanized and the plantar muscle harvested and processed. Results Cross-sectional area, peripheral nuclei and muscle fiber counts, nucleus/fiber ratio and smallest muscle fiber width did not differ significantly between groups. Morphological analysis revealed hypertrophic fibers in the Swim Group and evident muscle damage in the Swim plus Sericin and Injury Groups. The percentage of intramuscular collagen was apparently maintained in the Swim Group compared to remaining groups. Conclusion Combined treatment with sericin and swimming exercise did not improve muscle properties. However, physical exercise alone was effective in maintaining intramuscular connective tissue and preventing progression of deleterious effects of peripheral nerve injury.

RESUMO Objetivo Analisar o efeito da proteína sericina associada ao exercício físico de natação na histomorfometria do músculo plantar de ratos Wistar. Métodos Foram utilizados 40 ratos adultos divididos aleatoriamente em 5 grupos, com 8 animais cada: Controle, Lesão, Sericina, Natação, Natação e Sericina. Três dias após a compressão do nervo isquiático, os Grupos Natação e Exercício e Sericina foram submetidos ao exercício físico de natação durante 21 dias. Após, os animais foram sacrificados, e o músculo plantar foi processado. Resultados Não houve diferença da área da secção transversa entre os grupos, quantidade de núcleos periféricos, quantidade de fibra, relação núcleo/fibra e diâmetro menor. A análise morfológica revelou que no Grupo Natação ocorreu hipertrofia das fibras, assim como nos Grupos Exercício e Sericina e Lesão, o dano muscular foi evidente. O percentual de conjuntivo intramuscular parece ter sido mantido no Grupo Exercício em relação aos demais grupos. Conclusão A associação da proteína sericina e exercício físico de natação não foi eficiente na melhora das propriedades musculares, embora a aplicação do exercício físico tenha sido eficiente na manutenção do conjuntivo intramuscular, e no não agravamento dos efeitos deletérios consequentes da lesão nervosa periférica.
