ABSTRACT

Abstract BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation. OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series. DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil. METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated. RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample. CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

ABSTRACT

Resumo A artéria femoral profunda, devido às suas características anatômicas, se encontra protegida da maioria dos traumatismos vasculares. Relatamos um caso de pseudoaneurisma de ramo perfurante da artéria femoral profunda, associado à fístula arteriovenosa, secundário a rotura completa do músculo vasto medial em paciente jogador de futebol. A ressonância magnética demonstrou lesão muscular associada a pseudoaneurisma, e a angiotomografia confirmou a presença de pseudoaneurisma associado a fístula arteriovenosa de ramo da artéria femoral profunda. Foi realizado tratamento endovascular da fístula através da embolização com micromolas fibradas e drenagem cirúrgica do hematoma muscular. O paciente evoluiu bem, sem queixas clínicas no 30º dia de pós-operatório e também após 1 ano.


Abstract Due to its anatomical characteristics, the deep femoral artery is protected from most vascular injuries. We report a case of a soccer player with pseudoaneurysm of a perforating branch of the deep femoral artery, associated with an arteriovenous fistula and secondary to complete rupture of the vastus medialis muscle. Magnetic resonance imaging showed muscle damage associated with a pseudoaneurysm and angiotomography confirmed the presence of a pseudoaneurysm associated with a deep arteriovenous fistula of a branch of the deep femoral artery. Endovascular treatment of the fistula was performed by embolization with fibrous microcoils and surgical drainage of the muscle hematoma. The patient recovered well, was free from clinical complaints on the 30th postoperative day and also after 1 year.

ABSTRACT

Resumo Contexto O ultrassom contrastado por microbolhas (CMUS) é uma modalidade diagnóstica de acurácia bem demonstrada por estudos internacionais para seguimento de reparo endovascular do aneurisma de aorta abdominal (EVAR). Não existem, no entanto, estudos nacionais focados nesse método de seguimento. Objetivos O objetivo deste estudo foi relatar a experiência inicial com CMUS em um hospital terciário, traçando uma comparação dos achados do CMUS com o ultrassom Doppler convencional (USGD), com o intuito de verificar se a adição de contraste ao protocolo padrão de controle ultrassonográfico incorreu alteração nos achados. Métodos Entre 2015 e 2017, 21 pacientes em seguimento de EVAR foram submetidos ao USGD seguido de CMUS. Foram avaliados os achados de exame referentes à identificação de complicações, bem como à capacidade de identificação da origem da endofuga. Resultados Entre os 21 casos avaliados, 10 complicações foram evidenciadas no total: sete pacientes apresentaram endofuga (33,3%); dois pacientes apresentaram estenose em ramo de endoprótese (9,52%); e um paciente apresentou dissecção em artéria ilíaca externa (4,76%). Em 21 pacientes avaliados, o uso combinado dos métodos identificou 10 casos de complicações pós-EVAR. Em seis dos sete casos de endofugas (85,71%), o uso dos métodos combinados foi capaz de identificar a origem. O USGD isolado falhou na identificação da endofuga em dois casos (28,5%), identificando achados duvidosos em outros dois casos (28,5%), que obtiveram definição diagnóstica após associação do CMUS. Conclusões O CMUS é uma técnica de fácil execução, a qual adiciona subsídios ao seguimento de EVAR infrarrenal.


Abstract Background Microbubble contrast enhanced ultrasound (CEUS) is an accurate diagnostic method for follow-up after endovascular abdominal aortic aneurysm repair (EVAR) that has been well-established in international studies. However, there are no Brazilian studies that focus on this follow-up method. Objectives The objective of this study was to report initial experience with CEUS at a tertiary hospital, comparing the findings of CEUS with those of conventional Doppler ultrasound (DUS), with the aim of determining whether addition of contrast to the standard ultrasonographic control protocol resulted in different findings. Methods From 2015 to 2017, 21 patients in follow-up after EVAR underwent DUS followed by CEUS. The findings of these examinations were analyzed in terms of identification of complications and their capacity to identify the origin of endoleaks. Results There was evidence of complications in 10 of the 21 cases examined: seven patients exhibited endoleaks (33.3%); two patients exhibited stenosis of a branch of the endograft (9.52%); and one patient exhibited a dissection involving the external iliac artery (4.76%). In the 21 patients assessed, combined use of both methods identified 10 cases of post-EVAR complications. In six of the seven cases of endoleaks (85.71%), use of the methods in combination was capable of identifying the origin of endoleakage. DUS alone failed to identify endoleaks in two cases (28.5%) and identified doubtful findings in another two cases (28.5%), in which diagnostic definition was achieved after employing CEUS. Conclusions CEUS is a technique that is easy to perform and provides additional support for follow-up of infrarenal EVAR.

ABSTRACT

Abstract Hyperhidrosis (HH) is characterized by sweating exceeding the amount necessary to meet the thermal regulation and physiological needs of the body. Approximately 9.41% of individuals with HH have craniofacial hyperhidrosis (FH). The present study aims to review the most current data in the literature regarding craniofacial hyperhidrosis, including pathophysiology, diagnosis and clinical presentation, treatment options (clinical and surgical), and outcomes. VATS (videothoracoscopy sympathectomy) is considered the gold standard for definitive treatment of axillary or palmar hyperhidrosis. Recently, several studies have shown the usefulness of clinical treatment with oxybutynin hydrochloride, leading to clinical improvement of HH in more than 70% of users. Both clinical and surgical treatment of craniofacial hyperhidrosis have good results. However, surgical treatment of FH is associated with more complications. Clinical treatment with oxybutynin hydrochloride yields good results and can be the first therapeutic option. When the patient is not satisfied with this treatment and has good clinical conditions, surgical treatment can be used safely.


Resumo A hiperidrose (HH) é caracterizada por transpiração além da quantidade necessária para manter a regulação térmica e as necessidades fisiológicas do corpo. Aproximadamente 9,41% dos indivíduos com HH apresentam hiperidrose craniofacial (FH). Este estudo tem como objetivo revisar os dados mais atuais da literatura sobre FH, incluindo fisiopatologia, diagnóstico e apresentação clínica, opções de tratamento (clínico e cirúrgico) e desfechos. A simpatectomia por videotoracoscopia (VATS) é considerada o padrão-ouro para o tratamento definitivo da hiperidrose axilar ou palmar. Recentemente, vários estudos demonstraram a utilidade do tratamento clínico com cloridrato de oxibutinina, que leva à melhora clínica da HH em mais de 70% dos pacientes. O tratamento clínico e o cirúrgico apresentam bons resultados no tratamento da FH. No entanto, o tratamento cirúrgico da FH apresenta mais complicações. O tratamento clínico com cloridrato de oxibutinina fornece bons resultados e pode ser a primeira opção terapêutica. Quando o paciente não está satisfeito com esse tratamento e mostra boas condições clínicas, o tratamento cirúrgico pode ser usado com segurança.

ABSTRACT

Abstract Endovascular aneurysm repair is currently the most frequently treatment modality for infrarenal aortic aneurysms. Endoleaks are the most common cause of reintervention after endovascular aneurysm repair. It is often unclear which type of endoleak is the correct diagnose, making the treatment decision difficult. We report the case of a 72-year-old man with an endoleak two years after endovascular aneurysm repair. Images suggested a type III endoleak, but this was not confirmed by contrast aortography. We proceeded with the investigation using aortography with carbon dioxide and observed a type IA endoleak. This was successfully treated by implantation of a proximal cuff. A review of the literature shows that the role of carbon dioxide in endoleak management is still unclear. We present a case in which carbon dioxide was essential to both diagnosis and therapeutic decision-making in a type IA endoleak.


Resumo O tratamento endovascular dos aneurismas de aorta abdominal é atualmente a modalidade de tratamento mais comum. Os endoleaks representam a causa mais frequente de reintervenção após o tratamento endovascular. O diagnóstico do tipo de endoleak frequentemente é incerto, tornando o tratamento desafiador. Apresentamos o caso de um paciente de 72 anos, com endoleak após 2 anos de tratamento endovascular de aneurisma de aorta abdominal. Os exames de imagem pré-operatórios sugeriam um endoleak tipo III; entretanto, durante aortografia com contraste iodado, não foi possível identificá-lo. Optamos por realizar aortografia com dióxido de carbono (CO2), sendo, então, identificado um endoleak tipo IA, que foi tratado com sucesso com o uso de uma extensão (cuff) proximal. O papel do CO2 no diagnóstico de endoleaks ainda não está claro. Relatamos um caso em que o uso do CO2 foi essencial para o diagnóstico e para a decisão de tratamento do endoleak tipo IA.

ABSTRACT

O diabetes mellitus (DM) tem incidência de 2 a 5% nas populações ocidentais, além disso, 40 a 45% de todos os amputados são diabéticos. O DM consiste em fator de risco para aterosclerose e apresenta alta prevalência de doença arterial oclusiva. A macroangiopatia é acometida de forma mais difusa, mais grave e em idade mais precoce, conforme os mecanismos: alteração dos lipídeos e lipoproteínas, alteração da função plaquetária e alteração da função endotelial. O quadro clínico é variável e depende do nível de acometimento vascular e nervoso, podendo variar de claudicação intermitente à isquemia crítica (dor de repouso e lesão trófica). A anamnese e o exame físico são suficientes para determinarem a lesão arterial, o grau de neuropatia periférica e se há ou não infecção. Os exames complementares são importantes para o planejamento da conduta terapêutica: detector ultrassônico de fluxo para mensuração de índice pressórico tornozelo- braço (ITB), ecografia doppler, angiorressonância nuclear magnética, angiotomografia e arteriografia. O tratamento é baseado no quadro clínico e pode variar entre tratamento clínico, tratamento das feridas e tratamento cirúrgico para revascularização do membro


Diabetes mellitus (DM) has an incidence of 2 to 5% in Western populations, and 40 to 45% of all amputees are diabetic. DM is a risk factor for atherosclerosis and presents with a high prevalence of occlusive arterial disease. Macroangiopathy is more diffuse, more severe, and presents at an earlier age, depending on the mechanisms: changes in lipids and lipoproteins, changes in platelet function and changes in endothelial function. The clinical symptoms are variable and depend on the level of vascular and nerve involvement, and may range from intermittent claudication to critical ischemia (resting pain and trophic lesion). Anamnesis and physical examination are sufficient to determine the arterial lesion, the degree of peripheral neuropathy and whether or not there is infection. Complementary exams are important for planning the therapeutic management: ultrasound flow detector for measuring the ankle brachial index (ABI), Doppler ultrasound, magnetic resonance angiography, angiotomography and arteriography. Treatment is based on the clinical symptoms, and may range from clinical treatment, wound treatment, and surgical treatment to limb revascularization.
