Se destacó como la técnica quirúrgica más empleada la desinserción del escaleno anterior, seguida por la resección de la primera costilla. La lesión pleural y neural aparecieron como las complicaciones más frecuentes. Se constató la mejoría clínica de los pacientes luego de la intervención quirúrgica en la mayoría de los casos. Conclusiones: Se demostró que el tratamiento quirúrgico del síndrome de la salida torácica puede ser una alternativa efectiva para los pacientes aquejados por esta entidad(AU)

Introduction: Thoracic outlet syndrome covers various disorders, which occur as a result of intermittent or persistent compression of the different elements that leave the chest to the arm and cause vascular, neurological or combined symptoms, which often have a surgical indication for their resolution. Objective: Assess the results of ten years of experience in the surgical treatment of thoracic outlet syndrome in patients operated on at "Dr. Agostinho Neto" General Teaching Hospital in Guantánamo. Methods: A retrospective cross-sectional study was conducted in patients diagnosed with thoracic outlet syndrome in the Angiology and Vascular Surgery Service of "Dr. Agostinho Neto" General Teaching Hospital, Guantánamo , who underwent surgical treatment in the period 2009-2019. The following variables were evaluated: age, sex, diagnosed syndromes, surgical techniques, complications, and symptoms before and after surgery. Results: The female sex predominated, mainly in the ages from 40 to 50. Pain was the predominant symptom, and the costo-clavicular syndrome turned out to be the most diagnosed one. The most used surgical technique was the disinsertion of the anterior scalene, followed by the resection of the first rib. Pleural and neural injury appeared as the most frequent complications. The clinical improvement of patients after surgical intervention was found in most cases. Conclusions: It was demonstrated that surgical treatment of thoracic outlet syndrome can be an effective alternative for patients suffering from this entity(AU)

Carotid intraplaque neovascularization is correlated with the risk of revascularization following percutaneous coronary intervention / 南方医科大学学报

OBJECTIVE@#To investigate the correlation of intraplaque neovascularization (IPN) detected by carotid contrast-enhanced ultrasound (CEUS) with revascularization in patients following percutaneous coronary intervention (PCI).@*METHODS@#This study was conducted among 105 patients who were followed up for more than 12 months after PCI. All the patients received CEUS examination for assessment of carotid plaque formation and IPN, which were compared between patients with revascularization (REV group, n=27) and those without revascularization (N-REV group, n=78). ROC curve was used to analyze the diagnostic efficacy of CEUS for predicting revascularization. Univariate and multivariate logistic regression analyses were performed to identify the risk factors associated with revascularization.@*RESULTS@#In the REV group, the IPN score was 0 in 1 (3.7%) patient, 1 in 8 (29.6%) patients, 2 in 15 (55.6%) patients and 3 in 3 (11.1%) patients. Significant differences were noted between REV and N-REV groups in plaque length (15.70±6.93 vs 12.10±6.64, P < 0.05), maximum plaque thickness (3.69±1.12 vs 3.14±1.18, P < 0.05) and IPN (1.74±0.71 vs 0.87±0.63, P < 0.001). IPN score was identified as an independent risk factor for revascularization in patients following PCI, and at the cutoff value of 1.5, its sensitivity, specificity, positive predictive value, and negative predictive value for predicting the occurrence of revascularization were 74%, 89%, 69%, and 91%, respectively, with an AUC of 0.848 (95% CI: 0.703-0.905, P < 0.001).@*CONCLUSION@#CEUS allows noninvasive and semi-quantitative assessment of neovascularization in carotid artery plaques, and IPN detected by CEUS is correlated with the risk of revascularization in patients following PCI.

Clinical observation on filiform-fire needling of "Biaoben acupoint combination" for 33 cases of sequelae of coronavirus disease 2019 during recovery period / 中国针灸

OBJECTIVE@#To observe the clinical therapeutic effect of filiform-fire needling of "Biaoben acupoint combination" on the sequelae of patients with coronavirus disease 2019 (COVID-19) during the recovery period.@*METHODS@#A total of 33 patients with COVID-19 during the recovery period were treated with filiform-fire needling at the acupoints of Mingmen (GV 4), Shenzhu (GV 12), Gaohuang (BL 43), Zusanli (ST 36) and Shangjuxu (ST 37), etc., once every other day, 3 times a week, and 3 times was one course of treatment and totally 2 courses of treatment were required. The TCM symptom, Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) scores, pulmonary function indexes (forced vital capacity [FVC], forced expiratory volume in one second [FEV1], peak expiratory flow [PEF]) and chest CT imaging change were observed before and after treatment, and the therapeutic effect was evaluated.@*RESULTS@#After treatment, the scores of TCM symptom, HAMA and HAMD were decreased compared with those before treatment (P<0.05), and the levels of FVC, FEV1 and PEF were increased compared with those before treatment (P<0.05), and the recovery rate of 22 patients with pulmonary ventilation dysfunction was 86.4% (19/22). After treatment, the lung shadow area was smaller than that before treatment (P<0.05). The effective rate of 25 patients with lung CT abnormalities was 84.0% (21/25). After treatment, 23 cases were cured, 5 cases were markedly effective, 4 cases were effective, 1 case was ineffective, the cured and markedly effective rate was 84.8%.@*CONCLUSION@#The filiform-fire needling of "Biaoben acupoint combination" could significantly reduce the sequelae of cough, fatigue, chest tightness, etc. and mental symptoms such as anxiety and depression in patients with COVID-19 during the recovery period, and promote inflammatory exudation absorption of pulmonary lesion and improve lung ventilation function.

Chiropractic plus plum-blossom needling combined with flexibility training on attention deficit in mentally-retarded adolescents / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of chiropractic plus plum-blossom needling combined with flexibility training for attention deficit in mentally-retarded adolescents.@*METHODS@#Thirty adolescents with mild mental retardation were randomly divided into a medical rehabilitation plus flexibility training group (10 cases, 2 cases dropped off), a flexibility training group (10 cases, 1 case dropped off) and a control group (10 cases). The patients in the flexibility training group received flexibility training, once every other day, 3 times a week for 12 weeks. The patients in the medical rehabilitation plus flexibility training group received chiropractic and plum-blossom needling at Baihui (GV 20) and Sishencong (EX-HN 1) on the basis of the treatment in the flexibility training group, once every other day, 3 times a week for 12 weeks. The patients in the control group did not receive any targeted physical training and medical rehabilitation. Tobii Pro Spectrum eye movement instrument was used to test the attention concentration (T), attention span (M), attention transfer (γ%) and attention distribution (η).@*RESULTS@#Compared before treatment, T and M in the medical rehabilitation plus flexibility training group and the flexibility training group were increased after treatment (P<0.01, P<0.05), and γ% in the medical rehabilitation plus flexibility training group was increased after treatment (P<0.05). The increasing range of T, M and γ% in the medical rehabilitation plus flexibility training group and the flexibility training group was greater than that in the control group (P<0.01), and the increasing range of T and γ% in the medical rehabilitation plus flexibility training group was greater than that in the flexibility training group (P<0.05).@*CONCLUSION@#The chiropractic plus plum blossom needling combined with flexibility training can improve the attention deficit in mentally-retarded adolescents.

Lateral needling at Lianquan (CV 23) for post-stroke dysphagia: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of lateral needling at Lianquan (CV 23) for post-stroke dysphagia, and explore its mechanism.@*METHODS@#A total of 64 patients with post-stroke dysphagia were randomly divided into an observation group and a control group, 32 cases in each group. Both groups were treated with conventional basic treatment. The observation group was treated with lateral needling at CV 23, without needle retaining, once a day. The control group was treated with swallowing rehabilitation training, once a day. Both groups were treated for 5 days a week, with 2 days interval, 1 week as one course and 4 courses were required. Before and after treatment, the Kubota water swallowing test grade and standardized swallowing assessment (SSA) score were compared in the two groups. Before and after treatment, the video fluoroscopic swallowing study (VFSS) was used to measure the hyoid bone movement displacement and pharyngeal delivery time in the observation group.@*RESULTS@#Compared before treatment, the Kubota water swallowing test grade after treatment was improved in the two groups (P<0.05), and the observation group was superior to the control group (P<0.05); the SSA scores after treatment were decreased in the two groups (P<0.05), and the observation group was lower than the control group (P<0.05). Compared before treatment, the hyoid bone movement displacement was increased and pharyngeal delivery time was shortened after treatment in the observation group (P<0.05).@*CONCLUSION@#Lateral needling at CV 23 could improve dysphagia symptoms in patients with post-stroke dysphagia, its mechanism may be related to the increasing of hyoid bone movement displacement and shortening of pharyngeal delivery time.

GAO Shu-zhong's clinical experience in "seeking yin from yang needling method" based on "qi street" and "four seas" theories / 中国针灸

The paper introduces professor GAO Shu-zhong's understanding on "seeking yin from yang needling method" and its clinical application on the basis of "qi street" and "four seas" theories. Through professor GAO's clinical practice for years, he integrates and extendes the theories of "seeking yin from yang", "qi street" and "four seas" in Huangdi Neijing (The Yellow Emperor's Inner Classic). In this specific acupuncture method, in reference with the theories of "qi street" and "four seas", acupuncture is exerted on yang part of body, e.g. the back and lumber region to treat the diseases of yin parts, e.g. the chest and abdomen, which is differentiated as yin-yang imbalance in pathogenesis. In order to fully explain the clinical curative effect of "seeking yin from yang needling method", the common diseases in clinic, e.g. the disorders of heart, spleen and stomach systems, as well as the gynecology are taken as examples in the paper.

Epidemiological analysis of lower limb revascularization for peripheral arterial disease over 12 years on the public healthcare system in Brazil / Análise epidemiológica da revascularização de membros inferiores para doença arterial periférica em 12 anos no sistema público de saúde do Brasil

Abstract Background Worldwide, peripheral arterial disease (PAD) is a disorder with high morbidity, affecting more than 200 million people. Objectives Our objective was to analyze surgical treatment for PAD provided on the Brazilian Public Healthcare System over 12 years using publicly available data. Methods The study was conducted with analysis of data available on the Brazilian Health Ministry's database platform, assessing distributions of procedures and techniques over the years and their associated mortality and costs. Results A total of 129,424 procedures were analyzed (performed either for claudication or critical ischemia, proportion unknown). The vast majority of procedures were endovascular (65.49%) and this disproportion exhibited a rising trend (p<0.001). There were 3,306 in-hospital deaths (mortality of 2.55%), with lower mortality in the endovascular group (1.2% vs. 5.0%, p=0.008). The overall governmental expenditure on these procedures was U$ 238,010,096.51, and endovascular procedures were on average significantly more expensive than open surgery (U$ 1,932.27 vs. U$ 1,517.32; p=0.016). Conclusions Lower limb revascularizations were performed on the Brazilian Public Healthcare System with gradually increasing frequency from 2008 to 2019. Endovascular procedures were vastly more common and were associated with lower in-hospital mortality rates, but higher procedure costs.

Resumo Contexto A doença arterial periférica (DAP) é uma doença com alta morbidade global, afetando mais de 200 milhões de pessoas. Objetivos Neste estudo, analisamos o tratamento cirúrgico para DAP no sistema público de saúde do Brasil no período de 12 anos, com base em dados publicamente disponíveis. Métodos O estudo foi conduzido a partir da análise de dados disponíveis na plataforma do Departamento de Informática do Sistema Único de Saúde (DATASUS), do Ministério da Saúde, avaliando a distribuição da técnica cirúrgica utilizada, a mortalidade e o custo ao longo dos anos. Resultados Um total de 129.424 procedimentos foram analisados (para claudicantes e isquemia crítica, em proporção desconhecida). A maiora dos procedimentos foi via endovascular (65,49%), com tendência de aumento nessa desproporção (p < 0,001). Houve 3.306 mortes intra-hospitalares (mortalidade de 2,55%) com menor mortalidade no grupo endovascular (1,2% vs. 5,0%; p = 0,008). O investimento governamental total para esses procedimentos foi de US$ 238.010.096,51, e os procedimentos endovasculares foram significativamente mais caros que a cirurgia aberta convencional (US$ 1.932,27 vs. US$ 1.517,32; p = 0,016). Conclusões No sistema público de saúde brasileiro, as revascularizações de membros inferiores ocorreram com frequência crescente entre 2008 e 2019. Os procedimentos endovasculares foram mais comuns e relacionados a menor mortalidade intra-hospitalar, mas a maiores custos.

Acesso cirúrgico ao segmento cervical distal da artéria carótida interna e à bifurcação carotídea alta - revisão integrativa da literatura e proposta de protocolo / Surgical access to the distal cervical segment of the internal carotid artery and to a high carotid bifurcation - integrative literature review and protocol proposal

Resumo Diversas manobras já foram descritas para o acesso ao segmento distal cervical da artéria carótida interna ou à bifurcação carotídea alta; entretanto, há divergências na sistematização dessas técnicas. O objetivo deste estudo é revisar as técnicas descritas e propor um protocolo prático que auxilie na seleção da técnica mais adequada para cada caso. Para isso, foi realizada uma busca nas bases de dados PubMed Central, Biblioteca Virtual em Saúde e SciELO por artigos sobre o tema, em língua inglesa ou portuguesa, publicados entre os anos de 1980 e 2021. Entre as manobras descritas, parece razoável que as duas etapas iniciais sejam a abordagem ao músculo esternocleidomastóideo, seguida pela secção/retração do ventre posterior do músculo digástrico. Caso necessário, a subluxação mandibular temporária unilateral é um recurso adicional e preferível à divisão do aparato estiloide, devido ao menor potencial de morbidade. Exposições ainda mais amplas podem ser obtidas com as osteotomias mandibulares.

Abstract Several different maneuvers have been described for obtaining access to the distal cervical segment of the internal carotid artery or to a high carotid bifurcation. However there are different approaches to systematization of these techniques. The objective of this study is to review the techniques described and propose a practical protocol to support selection of the most appropriate technique for each case. The review is based on the results of database searches on PubMed Central, the Virtual Health Library (BVSalud), and SciELO for articles on the subject published in English or Portuguese from 1980 to 2021. Among the different maneuvers described, it appears reasonable that the first two steps should be to obtain access at the sternocleidomastoid muscle, followed by section or retraction of the digastric muscle posterior belly. If needed, temporary unilateral mandibular subluxation is an additional resource that is preferable to division of the styloid apparatus process, because of its lesser potential for morbidity. Even wider exposure can be obtained using mandibular osteotomies.

Surgical repair of abdominal aortic aneurysms on the public health system in the largest city in Brazil: a descriptive analysis of in-hospital data on 2693 procedures over 10 years / Correção cirúrgica do aneurisma de aorta abdominal em 2. 693 procedimentos ao longo de 10 anos no sistema público de saúde: uma análise descritiva na maior cidade brasileira

Abstract Background From 1990 to 2015, mortality from aortic aneurysms increased 16.8% in Brazil. São Paulo is the largest city in Brazil and about 5 million people depend on the public health system there. Objectives To conduct an epidemiological analysis of abdominal aortic aneurysm surgeries in the city of São Paulo. Methods Infra-renal aortic aneurysm procedures performed over a decade (from 2008 to 2017) were studied using publicly-available platforms from the Unified Health System and DATASUS. Results 2693 procedures were analyzed; 66.73% were endovascular; 78.7% of patients were male; 70.7% were aged 65 years or more; 64.02% were elective hospital admissions. There were 288 in-hospital deaths (mortality: 10.69%). In-hospital mortality was lower for endovascular surgery than for open surgery; both for elective (4.13% versus 14.42%) and urgent (9.73% versus 27.94%) (p = 0.019) admissions. The highest volume hospital (n = 635) had the lowest in-hospital mortality (3.31%). USD 24,835,604.84 was paid; an average of $ 2,318.63 for elective open, $ 3,420.10 for emergency open, $ 12,157.35 for elective endovascular and $ 12,969.12 for urgent endovascular procedures. Endovascular procedure costs were statistically higher than the values paid for open surgeries (p <0.001). Conclusions Endovascular surgeries were performed twice as often as open surgeries; they had shorter hospital stays and lower mortality.

Resumo Contexto No Brasil, a mortalidade por aneurisma de aorta aumentou 16,8% de 1990 a 2015. São Paulo é a maior cidade do Brasil, e cerca de 5 milhões de pessoas dependem do sistema público de saúde. Objetivos Análise epidemiológica das cirurgias do aneurisma de aorta abdominal na cidade de São Paulo. Métodos As cirurgias para correção do aneurisma de aorta infrarrenal realizadas no período de uma década (de 2008 a 2017) foram estudadas utilizando-se plataformas publicamente disponíveis do Sistema Único de Saúde e do Departamento de Informática do Sistema Único de Saúde. Resultados Foram analisados ​​2.693 procedimentos, entre os quais 66,73% eram endovasculares. Entre os pacientes, houve predominância do sexo masculino (78,7%) e daqueles com 65 anos ou mais (70,7%). Um total de 64,02% eram admissões hospitalares eletivas. Ocorreram 288 óbitos hospitalares (mortalidade: 10,69%). A mortalidade durante a internação foi menor para cirurgia endovascular do que para cirurgia aberta tanto no contexto eletivo (4,13% versus 14,42%) quanto urgente (9,73% versus 27,94%) (p = 0,019). O maior volume (n = 635) apresentou menor mortalidade intra-hospitalar (3,31%). Foi pago um total de $24.835.604,84, sendo uma média de $2.318,63 para cirurgia abertura eletiva, $3.420,10 para cirurgia abertura de emergência, $12.157,35 para cirurgia endovascular eletiva e $12.969,12 para cirurgia endovascular na urgência. Os custos dos procedimentos endovasculares foram estatisticamente superiores aos valores pagos para as cirurgias abertas (p < 0,001). Conclusões Foram realizadas duas vezes mais cirurgias endovasculares do que abertas, as quais apresentaram menor tempo de internação e menor mortalidade.

Inpatient consultations with the vascular and endovascular surgery team at an academic tertiary hospital / Interconsultas realizadas pela equipe de cirurgia vascular e endovascular em um hospital universitário terciário

ABSTRACT Background Inpatient consultations are a fundamental component of practice in tertiary care centers. However, such consultations demand resources, generating a significant workload. Objectives To investigate the profile of inpatient consultations requested by other specialties and provided by the Vascular and Endovascular Surgery team at an academic tertiary hospital. Methods Prospective observational study. Results From May 2017 to May 2018, 223 consultations were provided, representing 2.2% of the workload. Most consultations were requested by Oncology (16.6%), Hematology (9.9%), Nephrology (9.0%), and Cardiology (6.3%). The leading reasons for inpatient consultation were: need for vascular access (51.1%) and requests to evaluate a vascular disease (48.9%). Acute venous diseases accounted for 19.3% of consultations, chronic arterial diseases for 14.8%, acute arterial diseases for 7.2%, diabetic feet for 5.4%, and chronic venous diseases accounted for 2.2%. Surgical treatment was performed in 57.0%, either conventional (43.9%) or endovascular (13.0%). Almost all (98.2%) patients' issues were resolved. Conclusions Inpatient consultations with the Vascular and Endovascular Surgery team in a tertiary academic hospital accounted for 2.2% of the team's entire workload. Most patients were elective and underwent low-complexity elective surgical procedures. There may be an opportunity to improve healthcare, redirecting these patients to the outpatient flow.

RESUMO Introdução Interconsultas são um componente fundamental da prática clínica em centros de atendimento terciários. No entanto, esse tipo de consulta requer recursos, resultando em uma alta carga de trabalho. Objetivo Investigar o perfil das interconsultas solicitadas por outros departamentos e realizadas pela equipe de Cirurgia Vascular e Endovascular em um hospital universitário terciário. Métodos Estudo observacional prospectivo. Resultados De maio de 2017 a maio de 2018, foram realizadas 223 consultas, correspondendo a 2,2% da carga de trabalho. A maioria das consultas foram solicitadas pelos departamentos de Oncologia (16,6%), Hematologia (9,9%), Nefrologia (9,0%) e Cardiologia (6,3%). As principais razões das interconsultas foram a necessidade de acesso vascular (51,1%) e de avaliação de doenças vasculares (48,9%). As doenças venosas agudas corresponderam a 19,3% das avaliações; as doenças arteriais crônicas, a 14,8%; as doenças arteriais agudas, a 7,2%; o pé diabético, a 5,4%; e as doenças venosas crônicas corresponderam a 2,2%. Foi realizado tratamento cirúrgico em 57,0% dos casos, tanto convencional (43,9%) quanto endovascular (13,0%). Foram resolvidos os problemas de quase todos os pacientes (98,2%). Conclusão As interconsultas realizadas pela equipe de Cirurgia Vascular e Endovascular em um hospital universitário terciário corresponderam a 2,2% da carga de trabalho total. A maioria dos pacientes eram eletivos e foram submetidos a procedimentos cirúrgicos eletivos de baixa complexidade. O redirecionamento desses pacientes para o atendimento ambulatorial poderia auxiliar na melhoria dos serviços de saúde.

Impacto da COVID-19 no perfil cirúrgico dos pacientes de cirurgia vascular em serviço de referência em Curitiba / Impact of COVID-19 on the surgical profile of vascular surgery patients at a tertiary hospital in Curitiba, Brazil

Resumo Contexto Na pandemia de covid-19, os serviços de saúde diminuíram os atendimentos e procedimentos eletivos. Pacientes de cirurgia vascular são grupo de risco para adquirir formas graves da infecção, ao mesmo tempo que são suscetíveis a apresentar complicações de suas doenças de base caso não tenham acompanhamento rotineiro. Dessa forma, faz-se necessário entender os impactos e as consequências diretas e indiretas da pandemia com relação aos pacientes vasculares. Objetivos Avaliar o impacto de 1 ano de pandemia em um serviço de Cirurgia Vascular, assim como a mudança do perfil de cirurgias no mesmo período. Métodos Foi feita a análise de prontuários de pacientes submetidos a cirurgias eletivas e de urgência entre 2019 e 2021. Em conjunto, foi realizada uma revisão de literatura com as palavras-chave "cirurgia vascular", "covid-19" e "amputações". Os dados foram analisados com o programa computacional Stata/SE v.14.1 (StataCorpLP, EUA). Resultados Foram identificadas 1.043 cirurgias no período de estudo, sendo 51,6% pré-pandemia e 48,4% durante a pandemia. Observou-se redução no número de cirurgias eletivas e aumento no número de amputações de membros inferiores e desbridamentos cirúrgicos. Foi possível observar também aumento de pacientes com doença arterial obstrutiva periférica com classificação de Rutherford avançada, assim como de casos de pé diabético. Conclusões A diminuição dos atendimentos eletivos e o receio dos pacientes em procurar os serviços de saúde durante o período da pandemia são os prováveis motivos que justificam o aumento da gravidade dos quadros dos pacientes, com maior necessidade de amputação de membros inferiores, desbridamento cirúrgico e mudanças no perfil de cirurgia do serviço.

Abstract Background During the COVID-19 pandemic, healthcare services reduced the number of elective procedures performed. Vascular surgery patients are a group at risk of contracting severe forms of the infection, but are also susceptible to complications of their underlying diseases if they do not receive routine care. It is therefore necessary to understand the direct and indirect impacts and consequences of the pandemic on vascular patients. Objectives To assess the impact of 1 year of the pandemic on a vascular surgery service and changes to the profile of surgeries during the same period. Methods An analysis was conducted of the medical records of patients who underwent elective and emergency surgery from 2019 to 2021. A review of the literature was also conducted, using the search terms "vascular surgery", "COVID-19", and "amputations". Data were analyzed with Stata/SE v.14.1 (StataCorpLP, United States). Results A total of 1,043 surgeries were identified during the study period, 51.6% conducted pre-pandemic and 48.4% performed during the pandemic. There was a reduction in the number of elective surgeries and an increase in the number of lower limb amputations and surgical debridements. Increases were also observed in the proportion of patients with peripheral arterial occlusive disease with advanced Rutherford classifications and in the number of cases of diabetic foot. Conclusions The reduction in elective care and patients' reluctance to seek health services during the pandemic are the probable causes of increased severity of patient status, with greater need for lower limb amputation and surgical debridement and changes to the profile of the surgery performed at the service.

Tromboprofilaxia na cirurgia de varizes dos membros inferiores no Brasil / Thromboprophylaxis in lower limb varicose vein surgery in Brazil

Resumo Contexto Apesar de todo o investimento na profilaxia primária do tromboembolismo venoso (TEV) em pacientes cirúrgicos nos últimos anos, ainda não existem diretrizes específicas para aqueles que serão submetidos a procedimentos para tratamento de varizes de membros inferiores. Objetivos Avaliar o perfil de conduta de profilaxia do TEV pelos cirurgiões vasculares brasileiros para procedimentos de tratamento de varizes de membros inferiores. Métodos Pesquisa de levantamento por envio de questionário eletrônico a cirurgiões vasculares brasileiros. Os respondentes foram divididos entre os que realizam tratamento de veias safenas por cirurgia convencional e os que realizam termoablação para fim de comparação entre os grupos. Resultados Entre os 765 respondentes, o tratamento de escolha das veias safenas foi a cirurgia convencional para 405 (53%), espuma ecoguiada para 44 (6%) e termoablação (endolaser ou radiofrequência) para 199 (26%). Os cirurgiões que realizam termoablação prescrevem mais farmacoprofilaxia após o procedimento que aqueles que preferem cirurgia convencional (67/199, 34% vs. 112/405, 28%; p = 0,002). O grupo termoablação estratifica o paciente quanto ao risco de TEV com mais frequência que o grupo cirurgia convencional (102/199, 51% vs. 179/405, 44%; p =0,004). Ambos os grupos usam mais frequentemente enoxaparina como medicação para profilaxia, porém o grupo termoablação usa mais anticoagulantes orais diretos proporcionalmente que o grupo cirurgia convencional (26% vs. 10%, p < 0,001). Conclusões Cirurgiões vasculares brasileiros que fizeram o tratamento de veias safenas por termoablação prescrevem farmacoprofilaxia com maior frequência e por um período mais prolongado do que os que realizaram o tratamento por cirurgia convencional.

Abstract Background Despite all the investment in primary venous thromboembolism (VTE) prophylaxis for surgical patients in recent years, there are still no specific guidelines for those who undergo procedures to treat lower limb varicose veins. Objectives To evaluate the profile of VTE prophylaxis practices among Brazilian vascular surgeons conducting lower limb varicose vein procedures. Methods Survey design, sending an electronic questionnaire to Brazilian vascular surgeons. Respondents were divided between those who perform saphenous vein treatment with conventional surgery and those who perform thermoablation for the purpose of comparison between groups. Results Of 765 respondents, 405 (53%) treat saphenous veins with conventional surgery for, 44 (6%) with foam, and 199 (26%) with thermoablation (endolaser or radiofrequency). Surgeons who perform thermoablation prescribed more pharmacoprophylaxis after varicose vein surgery than those who perform conventional surgery (67/199, 34% vs. 112/405, 28%; p = 0.002). The thermoablation group stratifies patients for thromboembolism risk more frequently than the conventional surgery group (102/199, 51% vs. 179/405, 44%; p = 0.004). Both groups use enoxaparin as the most frequent drug for prophylaxis, but the thermoablation group uses proportionally more direct oral anticoagulants than the conventional surgery group (26% vs. 10%, p<0.001). Conclusions Brazilian vascular surgeons who perform saphenous vein treatment by thermoablation prescribe pharmacoprophylaxis more frequently and for a longer period than those who use conventional surgery.

Scourge of Peripheral Artery Disease in a Low-Income-Setting: The Role of VascularSurgery

Background: Peripheral artery disease (PAD) is a progressive disorder characterized by stenosis and/or occlusion of large and medium-sized arteries, other than those that supply the heart (coronary artery disease, CAD) or the brain (cerebrovascular disease). It is increasingly becoming a challenge in developing countries owing to poverty and ignorance. Objective: To review the scourge of peripheral artery diseases in our institution in a low-income setting with a view to determining the role of a vascular surgeon. Materials and method: Over a period of 15 years (2006 to 2021), patients with documented PAD were reviewed. Data of the patients were retrieved from the record department and such data included demography, aetiology/risk factors, clinical features and investigative parameters as well as modes of treatment especially vascular surgery. Results: There were 35 patients which comprised 20 males and 15 females with male to female ratio of 4:3. Age range affected most was 71-80 years. Aetiologically, artherosclerosis was dominant. Leriche Fontaine classification used in clinical evaluation showed that type III was dominant. 6 Ps (pain, pulselessness, paralysis, paraesthesie, pallor and poikilothermia) of vascular ischemia were evident. Doppler/duplex ultrasound and computer angiography were used in diagnosis. Medical and or surgical treatments were used in patients' management. Vascular and or orthopedic surgery played significant role. Conclusion: PAD affects the lower extremities more commonly than the upper extremity vessels especially in the elderly leading to intermittent claudicationn which is the most recognized symptomatic subset of lower extremity PAD.

Les morsures humaines représentent 3 % des morsures rencontrées au service d'urgence. Les preuves et le consensus sur les meilleures pratiques en matière de gestion des morsures humaines font défaut d'échec et de déterminer l'intérêt d'une réparation secondaire. Notre première tentative de reconstitution à partir de la pièce amputée étant échouée alors us avons entrepris cette étude dont les objectifs étaient d'identifier les facteurs OBSERVATION:Une patiente de sexe féminin âgée de 24 ans, ménagère A l'examen endo buccal, on notait une ouverture buccale d'amplitude normale. Les 32 et 31 sont exposées du fait de la perte de substance labiale. L'articulé dentaire conservée, l'hygiène bucco-dentaire défectueuse A l'admission, la patiente détenait dans un verre rempli d'eau minérale la pièce amputée de 2 cm x 1,8 cm dont la couleur laissait présager une vitalité compromise par défaut de vascularisation Les examens biologiques n'ont révélé aucune particularité. Le délai entre l'amputation et l'admission dans le Service était de 7h compromettant plus ou moins la vitalité de la pièce. Un délai nettement inférieur à celui trouvé par Roland et al. dans trois études différentes et qui ont trouvé moins de 14 % des patients ont été admis et plus de 80 % se sont présentés dans les 12 ou 24 heures suivant la morsure. CONCLUSION: Une tentative de replacement intentionnel d'une pièce amputée par morsure humaine sans chirurgie vasculaire est vouée à l'échec par une nécrose évolutive. Cependant la réparation chirurgicale de seconde intention donne un résultat esthétique et fonctionnel satisfaisant.

Morphological assessment of vascular anastomoses performed using high frequency electric welding / Evaluación morfológica de anastomosis vasculares realizada mediante soldadura eléctrica de alta frecuencia

SUMMARY: The studies of the properties of vascular structures and tissues during electric welding, in particular direct morphological changes in the blood vessel walls in the areas of welding processes, are of interest. Perforating veins, femoral veins, abdominal aorta, vena cava and porcine perforating veins of the limbs were used in this study. We performed end-to-end electric welding of the aorta, venous end-to-side electric welding, vein end-to-artery side arterial and venous welding, venous end-to-end electric welding, as well as arterial and venous lumen sealing.The results of histological studies showed the formation of a coagulated acellular protein matrix, represented by unorganized denatured protein fibrous structures. In the area of vascular tissue coagulation, lacunes were formed as a result of water evaporation from the biological tissue. In the perifocal area of the welded junction, cell reduction occurred without necrosis or charring. The data obtained confirm the safety of high frequency electric welding of the main vessels and the prospectfor clinical use of the studied techniques.

RESUMEN: Los estudios de las propiedades de las estructuras y tejidos vasculares durante la soldadura eléctrica son relevantes, en particular los cambios morfológicos directos en las paredes de los vasos sanguíneos en las áreas de los procesos de soldadura. En este estudio se utilizaron venas perforantes, venas femorales, parte abdominal de la aorta, vena cava y venas perforantes porcinas de los miembros. Realizamos soldadura eléctrica de extremo a extremo de la parte abdominal de la aorta, soldadura eléctrica de extremo a lado venosa, soldadura arterial y venosa de extremo a arteria del lado venoso, soldadura eléctrica de extremo a extremo venoso, así como lumen arterial y venoso. Los resultados de los estudios histológicos mostraron la formación de una matriz de proteína acelular coagulada, representada por estructuras fibrosas de proteínas desnaturalizadas no organizadas. Se formaron lagunas como resultado de la evaporación del agua del tejido biológico en el área de la coagulación del tejido vascular, En el área perifocal de la unión soldada, la reducción celular ocurrió sin necrosis ni carbonización. Los datos obtenidos confirman la seguridad de la soldadura eléctrica de alta frecuencia de los vasos principales y la perspectiva de uso clínico de estas técnicas.

Isolated Coarctation Repair in Neonates and Infants Through Left Thoracotomy: Short-Term Outcomes

Abstract Introduction: End-to-end anastomosis and extended end-to-end anastomosis are typically used as surgical approaches to coarctation of the aorta (CoAo) with access at the subclavian artery or an interposition graft. The objective of this study is to analyze the impact of surgical and anatomical characteristics and techniques on early outcomes after surgical treatment of CoAo without cardiopulmonary bypass through left thoracotomy. Methods: This is a quantitative, observational, and cross-sectional analysis of patients who underwent repair of CoAo between July 1, 2010 and December 31, 2017. Seventy-two patients were divided into three groups according to age: 34 in group A (≤ 30 days), 24 in group B (31 days to one year), and 14 in group C (≥ 1 year to 18 years). Results: Aortic arch hypoplasia was associated in 30.8% of the cases, followed by ventricular septal defect (13.2%). The preductal location was more frequent in group A (73.5%), ductal in group B (41.7%), and postductal in group C (71.4%). Long coarcted segment was predominant in groups A and C (61.8% and 71.4%, respectively) and localized in group B (58.3%). Extended end-to-end anastomosis technique was prevalent (68%), mainly in group A (91.2%). Mortality in 30 days was 1.4%. Conclusion: Most of the patients were children under one year of age, and extended end-to-end anastomosis was the most used technique, secondary to arch hypoplasia. Further, overall mortality was low in spite of moderate morbidity in the first 30 postoperative days.

Prevenção quaternária e a redução do fluxo de encaminhamentos à angiologia e pedidos de ultrassonografia Doppler / Quaternary prevention and reduction in the flow of referrals to angiology and the Doppler ultrasonography requests / Prevención cuaternaria y la reducción del flujo de referencias a angiología y pedidos de ultrasonografía Doppler

Introdução: A iatrogenia é uma causa importante de morbimortalidade, logo, a prevenção quaternária (P4), ação que ceifa a cascata diagnóstica supérflua, foi incluída como exercício de boa prática. A medicina de família e comunidade (MFC) introjeta a P4 na vivência, sendo capaz de usar ciência aliada a habilidades de comunicação para conhecer as pessoas, resolvendo assim cerca de 85% das queixas, o que inclui as de origem vascular. Existe uma alta demanda no Sistema Único de Saúde (SUS) tanto na marcação de exames quanto no encaminhamento para especialistas focais no que tange às queixas circulatórias, mas nem sempre encaminhar é oportuno. Nesse cenário, a MFC funciona como um caminho para a P4. Objetivos: O objetivo do presente estudo foi avaliar as referências para cirurgia vascular e angiologia e as solicitações de ultrassonografia (USG) Doppler de vasos de unidades de saúde da família (USFs) de João Pessoa/PB, analisando as taxas de solicitações por população adulta (>18 anos) adscrita, nas unidades conveniadas ao programa de residência em medicina de família e comunidade (PRMFC) há mais de 1 ano, há menos de 1 ano e naquelas sem convênio com PRMFC, sob o olhar crítico da P4. Métodos: Trata-se de um estudo transversal a partir de dados fornecidos pela Central de Regulação da Secretaria Municipal de Saúde de João Pessoa (SMS/JP), entre janeiro de 2017 e agosto de 2018. Para realização dos cálculos de correlação entre as variáveis estudadas, utilizou-se o teste de Kruskall-Wallis através do software SPSS 21.0. Resultados: O número total de pedidos de exames em análise foi de 3.918, oriundos de 90 USF, que somam uma população adscrita maior de 18 anos de 332.819 pessoas. Solicitou-se 1 Doppler a cada 85 habitantes adultos. Os resultados do estudo sugerem que os médicos residentes solicitam mais exames que os médicos não residentes, mas por outro lado apresentam menor taxa de encaminhamento aos especialistas. Conclusões: Estes achados podem sugerir que os médicos residentes encaminham menos, o que pode estar relacionado ao aumento da resolubilidade da atenção primária à saúde (APS) e ao ensino da P4 sob orientação de um médico de família e comunidade preceptor. Entretanto, novos delineamentos de pesquisa são necessários para melhor elucidar esta hipótese.

Introduction: Iatrogenesis is an important cause of morbimortality and quaternary prevention (P4), an action that reduces the superfluous diagnostic cascade, was included as an exercise of good practice. Family practice projects P4 into practice, being able to use science combined with communication skills to know people, solving about 85% of complaints, including vascular discomforts. There is a high demand at Sistema Único de Saúde (SUS) both in scheduling exams and referrals to focal specialists with regard to circulatory complaints, but referring is not always appropriate. In this scenario, family practice works as a pathway to P4. Objectives: The aim of the present study was to evaluate the referrals for vascular surgery/angiologist and requests for Doppler ultrasonography (USG) of vessels from family health units (USF) in João Pessoa, PB, analyzing the rates of requests per registered adult population (>18-years-old) in the units affiliated to the family practice medical residency program (FPMRP) for more than a year, less than a year and in the non-affiliated ones, under P4's critical view. Methods: This is a cross-sectional study of data provided by the Regulation Center of the Municipal Health Department of João Pessoa, between January 2017 and August 2018. To perform the correlation calculations between the studied variables, Kruskall-Wallis' correlation test was used through the SPSS 21.0 software. Results: The total number of exam requests under analysis was 3,918, from 90 USF, which add up to an enrolled population over 18-years-old of 332,819 people. For every 85 adult inhabitants, one Doppler exam was requested. Data suggest that the resident doctors request more exams than the non-residents, but on the other hand they have lower rates of referrals to focal experts. Conclusions: These findings may suggest that resident physicians refer less, which may be related to the increase in the resolution of primary care and the teaching of P4 under the guidance of a family practice preceptor. However, new research designs are considered to better elucidate this hypothesis.

Introducción: La iatrogenia es una causa importante de morbilidad y mortalidad, por lo que se incluyó como ejercicio de buena práctica la prevención cuaternaria (P4), una acción que corta la cascada diagnóstica superflua. La medicina familiar y comunitaria (MFC) introduce la P4 en la práctica, siendo capaz de utilizar la ciencia aliada a las habilidades de comunicación para conocer a las personas, resolviendo así alrededor del 85% de las quejas, lo que incluye las quejas vasculares. En el Sistema Único de Salud (SUS) brasileño hay una gran demanda, tanto para programar exámenes como para derivar a los especialistas focales las dolencias circulatorias, pero la derivación no siempre es oportuna. En este escenario, la CBM funciona como una vía hacia la P4. Objetivo: El objetivo del presente estudio fue evaluar las referencias de cirugía vascular y angiología y las solicitudes de ultrasonografía Doppler (USG) de vasos de las unidades de salud de la familia (USF) de João Pessoa/PB, analizando las tasas de solicitudes por población adulta (>18 años) asignada, en las unidades asociadas al programa de residencia en medicina de la familia y de la comunidad (CFMRP) por más de 1 año, por menos de 1 año y en las que no tienen convenio con el CFMRP, bajo la visión crítica del P4. Métodos: Se trata de un estudio transversal de datos proporcionados por la Central de Regulación de la Secretaría Municipal de Salud de João Pessoa (SMS/JP), entre enero de 2017 y agosto de 2018. Se utilizó la prueba de Kruskall-Wallis para realizar los cálculos de correlación entre las variables estudiadas mediante el programa informático SPSS 21.0. Resultados: El número total de solicitudes de pruebas analizadas fue de 3.918, procedentes de 90 USF, que suman una población asignada mayor de 18 años de 332.819 personas. Se solicitó un Doppler por cada 85 habitantes adultos. Los resultados sugieren que los médicos residentes solicitan más pruebas que los no residentes, pero por otro lado tienen una tasa de derivación a especialistas más baja. Conclusiones: Estos resultados pueden sugerir que los médicos residentes derivan menos, lo que puede estar relacionado con la mayor resolutividad de la Atención Primaria de Salud (APS) y la enseñanza de la P4 bajo la dirección de un médico de familia y un preceptor comunitario. Sin embargo, se necesitan nuevos diseños de investigación para dilucidar mejor esta hipótesis.
