ABSTRACT
Resumo O cateter totalmente implantável (CTI) é utilizado na administração da quimioterapia. Em menos de 1% dos casos de complicação, pode ocorrer migração do CTI para quimioterapia para a circulação sistêmica. O objetivo deste estudo foi descrever um caso de migração do CTI para a veia hepática. Uma paciente do sexo feminino, de 44 anos de idade, teve diagnóstico de câncer de mama com indicação de quimioterapia neoadjuvante. Realizou-se a implantação de cateter port-a-cath. Durante o procedimento de punção do cateter, houve retorno normal de sangue, e foi realizada infusão de soro fisiológico. Em seguida, houve um aumento de volume no local do port e não retorno de sangue à aspiração. A radiografia de tórax mostrou embolização do cateter em topografia hepática. Retirou-se o cateter pela técnica do laço (sem complicações), e a paciente recebeu alta no dia seguinte. Possíveis alterações no funcionamento do CTI devem chamar atenção da equipe responsável.
Abstract A totally implantable venous access port (TIVAP) is used for chemotherapy administration. Venous port migration to the systemic circulation occurs in less than 1% of complications. The aim of this study is to describe a case of TIVAP migration to the hepatic vein. A 44-year-old female patient with breast cancer was prescribed neoadjuvant chemotherapy. A port-a-cath was surgically implanted for chemotherapy. During the port puncture procedure, blood returned normally when aspirated. When the port was first accessed and flushed with saline solution, swelling was observed at the port site and blood could no longer be aspirated. A chest radiography showed catheter embolization in the region of the hepatic vein. The catheter was retrieved using a snare technique (without complications) and the patient was discharged the next day. The care team should be alert to possible TIIVAP malfunction.

Objetivo: O objetivo deste estudo foi responder qual é a melhor técnica para remoção de pinos de fibra de vidro e pinos metálicos fundidos considerando tempo, preservação da estrutura dentária e custos. Métodos: Foi realizado um estudo in vitro, randomizado e cego. Sessenta dentes tratados endodonticamente foram randomizados em dois grupos de acordo com o tipo de pino. Uma segunda randomização foi realizada para cada tipo de técnica de remoção (ultrassom, broca ou combinada; n=10). One-way ANOVA foi usado para comparar o tempo de remoção do pino, teste t pareado comparou a quantidade de estrutura dentária removida e Kruskal Wallis seguido pelo teste post hoc de Mann-Whitney foram usados para análise de custo (P = 0,05). Resultados: Não houve diferença no tempo de remoção do pino considerando o tipo ou técnica do pino (P=0,630). A perda média de estrutura dentária na região cervical foi superior a 30% quando apenas uma ponta diamantada foi usada para remover pino de fibra de vidro (P<0,00001) e pino metálico fundido (P=0,008). Conclusão: De acordo com os resultados deste estudo, podemos concluir que a seleção da técnica de remoção dependerá da habilidade do operador, e sempre ocorrerá alguma perda de estrutura dentária, embora seja esperada uma perda maior quando apenas pontas diamantadas são usadas para este fim.(AU)
Objective: The aim of this study was to answer which is the best technique to removing glass fiber post and cast metal post considering time, preservation of tooth structure, and costs. Methods: An in vitro, randomized, blinded study was conducted. Sixty endodontically treated teeth were randomized into two groups according to post type. A second randomization was performed for each type of removal technique (ultrasound, drill, or combined; n=10). One-way ANOVA was used to compare the time to post removal, paired t-test compared the amount of tooth structure removed and Kruskal Wallis followed by post hoc Mann-Whitney test were used for cost analysis (P=0.05). Results: There was no difference in post removal time considering post type or technique (P=0.630). The average loss of tooth structure in the cervical region was greater than 30% when only a diamond bur was used to remove fiber glass post (P<0.00001) and cast metal post (P=0.008). Conclusion: According to the results of this study, we can conclude that the selection of the removal technique will depend on the skill of the operator, and some loss of tooth structure will always occur, although greater loss is expected when only diamond burs are used for this purpose.(AU)

La decanulación es el proceso de retirar la cánula de traqueotomía de forma definitiva, una vez que la patología original que motivó la traqueotomía se haya resuelto o mejorado significativamente.La predicción del éxito de decanulación es difícil debido a la influencia de varios factores. No existe un protocolo universalmente aceptado. Existen diversos protocolos y la elección depende, en gran medida, de cada institución y de la situación individual de cada paciente. Sin embargo, para lograr la decanulación exitosa deben tenerse en cuenta varios criterios esenciales que deben cumplirse independientemente del protocolo elegido.Se señalan las características que debe reunir el paciente apto para la decanulación y se presentan recomendaciones sobre los pasos necesarios para lograr el retiro de la cánula de traqueotomía en el niño de manera segura y minimizando el riesgo de fracaso.
Decannulation is the process of removing the tracheotomy cannula permanently, once the original pathology that led to the tracheotomy has been resolved or significantly improved. The prediction of decannulation success is difficult due to the influence of several factors. There is no universally accepted decannulation protocol. There are several protocols and the choice depends, largely, on each institution and the individual situation of each patient. However, in order to achieve successful decannulation, several essential criteria must be taken into account, which must be fulfilled regardless of the chosen protocol.We indicate the characteristics that the patient must meet for decannulation, and we present recommendations on the necessary steps to achieve the removal of the tracheotomy cannula in a child safely and minimizing the risk of failure.

El soporte ventilatorio no invasivo es una herramienta que ha demostrado mejorar la sobrevida de pacientes con falla muscular de la bomba respiratoria y el manejo de enfermedades pulmonares crónicas, incluso la ventilación no invasiva nocturna ha servido de puente hacia el trasplante pulmonar. Se presenta el caso de una adolescente de 14 años con enfermedad pulmonar crónica hipoxémica severa y falla ventilatoria secundaria, que requirió ventilación prolongada y traqueostomía en espera de trasplante pulmonar. Luego de reevaluar indemnidad de la vía aérea fue decanulada a soporte ventilatorio no invasivo, con uso alternado de mascarilla nasal nocturna y pieza bucal diurna, permitiendo descanso muscular respiratorio eficiente, y mejoría de flujo de tos con técnicas de apilamiento de aire. Este plan permitió una decanulación segura y realizar soporte continuo ventilatorio no invasivo con un programa de rehabilitación cardiorrespiratorio. Generalmente, el soporte ventilatorio no invasivo se utiliza en trastornos primarios de la bomba respiratoria. En este caso, se indicó para enfermedad pulmonar crónica hipoxémica, mostrando claros beneficios con oxigenación adecuada, buen rendimiento cardiovascular con mejor tolerancia al ejercicio y entrenamiento en el escenario de preparación al trasplante pulmonar.
Noninvasive Ventilatory Support has demonstrated to improve survival of patients with ventilatory pump muscle failure and nocturnal noninvasive ventilation is useful in chronic lung disease, even bridging to lung transplant. We present a 14 years old girl with severe hypoxemic chronic lung disease and secondary ventilatory failure, who required continuous long-term ventilation and underwent a tracheostomy waiting for lung transplant. After reevaluated the airway patency the patient was decannulated to Noninvasive Ventilation Support, alternating nocturnal nasal mask with diurnal mouth piece in order to provide efficient respiratory muscle rest, made air stacking and improved cough flow. This plan allows safe decannulation to continuous Noninvasive Ventilatory Support tailoring a rehabilitation cardiorespiratory program. Usually, Noninvasive Ventilation Support is prescribed for primary respiratory pump muscles failure, but in this case, it was applied for a hypoxemic chronic lung disease. Clear benefits were observed leading to appropriate oxygenation, good cardiovascular performance with better tolerance to exercise for training in the preparatory scenario of a lung transplant.

Tracheostomy (TQT) in pediatrics is a procedure that allows maintaining permeable airways and establishes prolonged mechanical ventilation. Continuous noninvasive ventilatory support (CNVS) can always be used for patients capable of cooperating with it and mechanical insufflation-exsufflation (MIE). Despite this, TQT continues to be indicated frequently, limiting home transfer and care, conditioning additional burden of morbidity and risks. In those with upper airway obstruction (OVAS), except in <2 years, the decanulation follows similar guidelines as in adults. Small children who require even only sleep ventilation cannot be decannulated to NVS if they cannot be relied on to use it via noninvasive interfaces. So, children under age 12 should not be decannulated unless they are ventilator weaned. For adolescents and adults, the principle criterion for safe decannulation is an MIE-peak exsufflation flows (MIE-EF) over 150 L/m whereas need for tracheotomy occurs when MIE-EF decrease below 120 L/m, irrespective of extent of ventilator dependence. The following article is a critical narrative review of different decannulation alternatives to ensure that this process can be safely carried out with effectiveness and efficiency. Patients with different ages and diseases have been considered, knowing that younger children and adult in transition tracheostomized patients significantly increases the challenges.
La traqueotomía (TQT) permite mantener la vía aérea permeable y la ventilación mecánica prolongada. El soporte ventilatorio no invasivo continuo (SVNI) junto con la insuflación-exuflación mecánica (MIE), son una alternativa en la mayoría de los casos. Pese a esto, la TQT sigue indicándose frecuentemente, limitando la transferencia al hogar, condicionando carga adicional de morbilidad. En los niños con obstrucción de la vía aérea superior (OVAS), salvo en los <2 años, la decanulación sigue lineamientos similares que en adultos. Los <12 años dependientes de ventilador, aun cuando sólo sea nocturna, son decanulados o extubados a SVNI más difícilmente que adultos con dependencia continua. La mejor estrategia es evitar la TQT e indicar SVNI en los pacientes colaboradores que cumplan criterios. Excepto pacientes con estridor por OVAS grave o enfermedad de la primera motoneurona y severo compromiso miopático. Para adolescentes y adultos, el criterio para la decanulación segura es un pico flujo exuflado máximo en MIE (PFE-MIE), con o sin tos, >150 L/m, mientras que la necesidad de traqueostomía ocurre cuando el MIE (PFE-MIE) esta bajo 120 ml/min, independiente del grado de dependencia del ventilador. En menores de 12 años, el éxito del SVNI reside en obtener interfaces confiables para su entrega, de lo contrario no podrían ser decanulados. Siendo escasos los protocolos de decanulación pediátrica. Nuestro objetivo es el de ponderar alternativas seguras y eficientes para la decanulación de la TQT. Siendo considerados pacientes con edades y enfermedades distintas, sabiendo que los más pequeños, no colaboradores y dependientes de ventilación aumentan el desafío.

Abstract Introduction: Indications for cardiac devices have been increasing as well as the need for lead extractions as a result of infections, failed leads and device recalls. Powered laser sheaths, with a global trend towards the in-creasingly technological tools, meant to improve the procedure's outcome but have economic implications. Objective: The aim of this study is to demonstrate the experience of a Bra-zilian center that uses simple manual traction in most lead removals per-formed annually, questioning the real need for expensive and technically challenging new devices. Methods: This retrospective observational study included 35 patients who had a transvenous lead extraction in the period of a year between January 1998 and October 2014 at Hospital de Messejana Dr. Carlos Alberto Studart Gomes, in Fortaleza, CE, Brazil. Data were collected through a records review. They were evaluated based on age, type of device, dwelling time, indication for removal, technique used and immediate outcomes. Results: The median dwelling time of the devices was 46.22 months. Infec-tion, lead fracture and device malfunction were the most common indica-tions. Simple traction was the method of choice, used in 88.9% of the pro-cedures. Manual traction presented high success rates, resulting in com-plete removal without complications in 90% of the cases. Conclusion: This article suggests that lead extraction by simple manual traction can still be performed effectively in countries with economic diffi-culties as a first attempt, leaving auxiliary tools for a second attempt in case of failure or contraindications to the simple manual traction technique.

ABSTRACT Purpose: Retained or forgotten ureteral stents (FUS) have a potential to cause significant morbidity as well as medico-legal issues and increased cost. We aimed to evaluate the efficacy and usefulness of smartphone-based Ureteral Stent Tracker (UST) application and compare the results with basic appointment card system to prevent FUS, prospectively. Materials and Methods: A total of 90 patients who underwent ureteroscopic stone treatment procedure with indwelling DJ stents were equally distributed into two groups. In group-1, patients were followed using UST application. In group-2, only appointment cards were given to the patients. Two groups were compared in terms of stent overdue times and complete lost to follow up rates. Results: Forty-four patients in group-1 and 43 patients in group-2 completed the study. Among patients, 22.7% in group-1 and 27.9% in group-2 did not return for the stent removal on the scheduled day. In group-1, these patients were identified using the UST and called for the stent removal on the same day. After 6 weeks of maximal waiting period, mean overdue times in group-1 and group-2 were 3.5 days and 20 days, respectively (p = 0.001). In group-2, 3 patients (6.9%) were lost to follow up, while in group-1, it was none (p = 0.001). Conclusions: We found that the patients who were followed by the smartphone-based UST application has less overdue times and lost to follow up cases compared to the basic appointment card system. The UST application easily follows patients with indwelling ureteral stents and can identify patients when overdue.

Abstract Introduction: In the last two decades, the increased number of implants of cardiac implantable electronic devices has been accompanied by an increase in complications, especially infection. Current recommendations for the appropriate treatment of cardiac implantable electronic devices-related infections consist of prolonged antibiotic therapy associated with complete device extraction. The purpose of this study was to analyze the importance of percutaneous extraction in the treatment of these devices infections. Methods: A systematic review search was performed in the PubMed, BVS, Cochrane CENTRAL, CAPES, SciELO and ScienceDirect databases. A total of 1,717 studies were identified and subsequently selected according to the eligibility criteria defined by relevance tests by two authors working independently. Results: Sixteen studies, describing a total of 3,354 patients, were selected. Percutaneous extraction was performed in 3,081 patients. The average success rate for the complete percutaneous removal of infected devices was 92.4%. Regarding the procedure, the incidence of major complications was 2.9%, and the incidence of minor complications was 8.4%. The average in-hospital mortality of the patients was 5.4%, and the mortality related to the procedure ranged from 0.4 to 3.6%. The mean mortality was 20% after 6 months and 14% after a one-year follow-up. Conclusion: Percutaneous extraction is the main technique for the removal of infected cardiac implantable electronic devices, and it presents low rates of complications and mortality related to the procedure.

Infecções relacionadas aos dispositivos eletrônicos cardíacos exigem sua completa remoção, sendo necessário o conhecimento das técnicas percutâneas de extração de cabos-eletrodos, evitando-se, assim, a cirurgia cardíaca com esternotomia e bypass cardiopulmonar. Apresentamos o caso de paciente do sexo feminino, com 23 anos de idade, portadora de bloqueio atrioventricular total congênito e marcapasso definitivo implantado há 18 anos, que evoluiu com infecção de loja relacionada a cirurgia recente. A paciente foi submetida a extração de cabos-eletrodos por meio de técnicas percutâneas, com sucesso, e recebeu implante de novo sistema à direita. A extração percutânea de cabos-eletrodos ainda é considerada um procedimento de alto risco, com significativas taxas de morbidade e mortalidade. Entre suas complicações, destacam-se: morte, lesão de grandes vasos, perfuração atrial, avulsão de estruturas cardíacas, lesão de valvas cardíacas, e embolização sistêmica. Embora o sucesso da extração de cabos-eletrodos seja dependente da experiência do médico e da disponibilidade de equipamentos adequados, também é especialmente dependente do tempo de implante dos cabos-eletrodos. A extração de cabos-eletrodos por abordagem percutânea pode ser realizada com segurança e eficácia quando utilizados material adequado e equipe treinada
Infections related to cardiac electronic devices require their complete removal, and percutaneous lead extraction techniques are required to avoid cardiac surgery with sternotomy and cardiopulmonary bypass. We present the case of a 23 year old female patient with third degree congenital atrioventricular block and definitive pacemaker implanted 18 years ago, evolving with a pocket infection related to a recent surgery. Electrode extraction was performed using percutaneous techniques and implanting a new system on the right. Percutaneous electrode extraction is still considered a high risk procedure with significant morbidity and mortality rates. Complications include: death, large vessel damage, atrial perforation, avulsion of cardiac structures, cardiac valve damage, and systemic embolization. Although a success electrode extraction depends on the physician's experience and the availability of suitable equipment, it is also especially dependent on the electrode implant time. Lead extraction using the percutaneous approach may be performed safely and effectively when appropriate materials are used in combination with a well-trained team.

ABSTRACT CONTEXT: Hardware breakage during hip surgery can pose challenging and difficult problems for orthopedic surgeons. Apart from technical difficulties relating to retrieval of the broken hardware, complications such as adjacent joint arthritis and damage to neurovascular structures and major viscera can occur. Complications occurring during the perioperative period must be informed to the patient and proper documentation is essential. The treatment options must be discussed with the patient and relatives and the implant company must be informed about this untoward incident. CASE REPORT: We report a case of complete removal of the implant and then removal of the broken guidewire using a combination of techniques, including a cannulated drill bit, pituitary forceps and Kerrison rongeur. CONCLUSIONS: We suggest some treatment options and recommendations for preventing an avoidable surgical catastrophe.
RESUMO CONTEXTO: Ruptura de material de síntese durante a cirurgia de quadril pode representar problemas desafiadores e difíceis para cirurgiões ortopédicos. Além de dificuldades técnicas com recuperação do material quebrado, complicações como artrite na articulação adjacente, danos às estruturas neurovasculares e às principais vísceras podem ocorrer. A complicação durante o período perioperatório deve ser informada ao paciente e documentação apropriada é essencial. As opções de tratamento devem ser discutidas com o paciente e seus familiares e a empresa do implante deve ser informada sobre este incidente desagradável. RELATO DE CASO: Nós relatamos um caso da remoção completa do implante e, em seguida, a remoção do fio-guia quebrado usando uma combinação de técnicas, incluindo uma broca canulada, fórceps da hipófise e rongeur de Kerrison. CONCLUSÕES: Sugerimos algumas opções de tratamento e recomendações para prevenir uma evitável catástrofe cirúrgica.

ABSTRACT Purpose: To analyze the indications for explantation or exchange of intraocular lenses (IOLs), which were originally implanted for the correction of aphakia during cataract extraction. Methods: All cases that involved intraocular lens explantation or exchange in one institution between January 2008 and December 2014 were analyzed retrospectively. Results: In total, 93 eyes of 93 patients were analyzed. The median time interval between implantation and explantation of the anterior chamber intraocular lenses (AC IOL) and posterior chamber intraocular lenses (PC IOL) was 83.40 ± 83.14 months (range: 1-276 months) and 55.14 ± 39.25 months (range: 1-168 months), respectively. Pseudophakic bullous keratopathy (17 eyes, 38.6%) and persistent iritis (12 eyes, 27.8%) in the AC IOL group and dislocation or decentration (30 eyes, 61.2%) and incorrect IOL power (nine eyes, 18.4%) in the PC IOL group were the most common indications for explantation of IOLs. The mean logMAR best corrected visual acuity (BCVA) improved significantly from 1.30 preoperatively to 0.62 postoperatively in the PC IOL group (p<0.001) but did not improve significantly in the AC IOL group (p=0.186). Conclusions: The primary indication for IOL explantation or exchange was pseudophakic bullous keratopathy in the AC IOL group and was dislocation or decentration in the PC IOL group. PC IOL explantation or exchange is safe and improves visual acuity. .
RESUMO Objetivo: Analisar as indicações para a remoção ou troca de lentes intraoculares (IOL), que foram originalmente implantadas para a correção de afacia após a extração da catarata. Método: Todos os casos que envolveram remoção ou troca de lentes intraoculares em uma única instituição, entre janeiro de 2008 e dezembro 2014 foram analisados retrospectivamente. Resultados: No total, foram analisados 93 olhos de 93 pacientes. O intervalo de tempo médio entre o implante e a remoção das LIOs de câmara anterior (AC IOL) e de câmara posterior (PC IOL) foi 83,40 ± 83,14 meses (variando de 1 a 276 meses) e 55,14 ± 39,25 meses (variando de 1 a 168 meses), respectivamente. Ceratopatia bolhosa pseudofácica (17 olhos, 38,6%) e irite persistente (12 olhos, 27,8%) no grupo AC IOL, e deslocamento ou descentralização (30 olhos, 61,2%) e poder incorreto da IOL (nove olhos, 18,4%), no grupo PC IOL, foram as indicações mais comuns para a remoção das IOLs. A média logMAR da melhor acuidade visual corrigida (BCVA) melhorou significativamente a partir de 1,30 no pré-operatório para 0,62 no pós-operatório no grupo PC IOL (p<0,001), mas não melhorou significativamente no grupo AC IOL (p=0,186). Conclusões: A principal indicação para remoção ou troca de lentes intraoculares foi a ceratopatia bolhosa pesudofácica no grupo AC IOL e deslocamento ou descentralização no grupo PC IOL. A remoção ou troca de PC IOLs é segura e melhora a acuidade visual. .

OBJETIVO El objetivo del presente estudio descriptivo es la valoración de un nuevo método de remoción de implantes oseointegrados bajo una técnica mínimamente invasiva. MATERIALES Y MÉTODOS El estudio fue desarrollado sobre un grupo de 66 implantes oseointegrados de conexión interna y externa diagnosticados en falla, a los cuales se les indicó su remoción quirúrgica por presentar un diagnóstico radiográfico de pérdida ósea periimplantaria, mal posicionamiento quirúrgico con imposibilidad de rehabilitación protésica o daño del elemento de retención protésico del implante. El procedimiento quirúrgico, el cual es de carácter ambulatorio, fue llevado a cabo en un pabellón bajo anestesia local. Como primera opción de remoción quirúrgica, el procedimiento consistió en la utilización de instrumental de remoción a contra-torque, sin la apertura de un colgajo de espesor total, y como segunda opción de remoción quirúrgica la utilización de una fresa trefina, para lo cual fue necesario realizar un colgajo de espesor total que expusiera el lecho implantario. RESULTADOS Se removieron un total de 66 implantes oseointegrados, todos bajo la primera modalidad de remoción a contra-torque con el nuevo instrumento, sin colgajo y sin la necesidad de usar fresa trefina. CONCLUSIONES Con las limitaciones de este estudio preliminar planteamos que la utilización del nuevo instrumento de remoción a contra-torque de implantes oseointegrados en fallo se vislumbra como una muy buena alternativa de remoción quirúrgica mínimamente invasiva, disminuyendo los riesgos quirúrgicos del uso de una fresa trefina, el daño a los tejidos aledaños.
OBJECTIVE The aim of this study is the evaluation of a new removal method of osseointegrated implants under a minimally invasive technique. MATERIALS AND METHODS The study was conducted on a group of 66 osseointegrated internal and external connection implants that were considered unsuccesful. The surgical removal was indicated after radiologically confirming peri-implant bone loss, and poor positioning which made the prosthetic rehabilitation impossible, or would damage the prosthetic implant retainer. The surgical procedure was developed in an operating room under local anesthesia. As first surgical removal option, the procedure consisted of the use of a removal instrument that works against torque and which does not need a full thickness flap to reach the surgical site; and as a second surgical removal option a trephine bur was used. For this option, a full thickness flap was performed in order to expose the surgical site. RESULTS A total of 66 osseointegrated implants were removed under the first mode, with no full thickness flaps or Trephine burs required. CONCLUSIONS Within the limitations of this preliminary study, we propose that the use of this new, against torque, removal instrument of osseointegrated implants in failure is seen as a very good alternative to invasive surgical removal techniques, reducing surgical risks.
