Short term outcomes of carotid surgery: the real-world experience of a single teaching center.

Background: Surgical treatment of symptomatic extracranial carotid stenosis is well established for preventing neurological events and should adhere to optimal quality standards. However, there is growing concern as to whether results of controlled trials are replicable in real-world settings. Objectives: To assess a symptomatic carotid stenosis population that underwent surgery and its short-term outcomes in a real-world context at a professional training center. Methods: Observational study using data collected from medical records from January 2012 to January 2023. Patients undergoing operations for other carotid diseases and with concomitant heart surgery were excluded. Results: A total of 70 patients undergoing angioplasty or carotid endarterectomy were included. Population subsets undergoing angioplasty or endarterectomy were similar. Differences in anesthetic modality and a longer operative time in the carotid endarterectomy subgroup were statistically significant. There were 4 cases of stroke, only 3 of which (2 minor and 1 major) were related to the index lesion. Thus, the rate of major operation-related stroke was 1.43% and the rate of any lesion-related stroke was 4.29%. There was 1 case of AMI in the angioplasty group and there were no deaths in the sample. The overall rate of major adverse cardiovascular events was 5.71%. There were no statistical differences between the endarterectomy and angioplasty groups regarding the main outcomes. Conclusions: The rates of outcomes of ischemic stroke, acute myocardial infarction, death, and major adverse cardiovascular events at this center are in line with the rates reported by randomized controlled trials, demonstrating the feasibility of carotid surgery in centers with teaching programs.

Desfechos de curto prazo da cirurgia de carótida: experiência no "mundo real" em um centro único de formação profissional / Short term outcomes of carotid surgery: the real-world experience of a single teaching center

Resumo Contexto A abordagem cirúrgica para estenose carotídea sintomática está consolidada na literatura para a prevenção de eventos neurológicos, devendo seguir padrões ótimos de qualidade. Entretanto, há uma crescente preocupação relacionada à possibilidade ou não de replicar os dados dos trabalhos controlados no mundo real. Objetivos Avaliar a população com estenose carotídea sintomática submetida a cirurgia e seus desfechos de curto prazo em um contexto de mundo real em um centro de formação profissional. Métodos Tratou-se de um estudo observacional realizado por meio de coleta de dados em prontuário de janeiro de 2012 a janeiro de 2023. Foram excluídos pacientes operados por outras etiologias e com cirurgia cardíaca concomitante. Resultados Foram incluídos 70 pacientes submetidos a angioplastia ou endarterectomia carotídea. Os subgrupos populacionais submetidos a angioplastia ou endarterectomia foram semelhantes. Houve diferença estatisticamente relevante quanto à modalidade anestésica e ao tempo cirúrgico maior para o subgrupo de endarterectomia carotídea. Houve quatro casos de acidente vascular encefálico isquêmico, e três deles estavam relacionados à lesão, sendo dois menores e um maior. Dessa forma, a taxa de acidente vascular encefálico maior relacionado à lesão foi de 1,43% e de qualquer acidente vascular encefálico relacionado à lesão, de 4,29%. A taxa total de eventos adversos cardiovasculares maiores foi de 5,71%. Houve um caso de infarto agudo do miocárdio no grupo angioplastia e nenhum óbito. Não houve diferença estatística entre os grupos de endarterectomia e angioplastia quanto aos desfechos principais. Conclusões Os desfechos acidente vascular encefálico isquêmico, infarto agudo do miocárdio, óbito e eventos adversos cardiovasculares maiores neste centro são semelhantes aos encontrados em estudos clínicos randomizados, demonstrando viabilidade da manutenção deste tratamento em centros com programas de ensino.

Imunodeficiência comum variável: relato de caso e revisão da literatura / Common variable immunodeficiency: case report and literature review

A Imunodeficiência comum variável (ICV) é a segunda mais frequente das imunodeficiências primárias e tem como critérios diagnósticos: infecções recorrentes; idade acima de 4 anos; níveis reduzidos de IgG, de IgA e/ou IgM; exclusão de outras causas de hipogamaglobulinemias; ausência de isohemaglutininas e de resposta vacinal. O artigo visa relatar o caso de um paciente com ICV associada a infecções/infestações recorrentes e esplenomegalia. Trata-se de menino de 8 anos com antecedente de oito pneumonias, giardíase recorrente e esplenomegalia com pesquisa de anticorpos anti-HIV negativa. Apresentava IgG=614mg/dl, IgM= 19mg/dl e IgA=24mg/dl; CD4=24% (742 células/mm3), CD8= 70% (2150 células/mm3), CD19 = 247células/mm3 e linfócito B total = 9,2%. A ICV pode se manifestar através de cinco fenótipos clínicos: infecções, autoimunidade, infiltração linfocítica, malignidade e enteropatia. Neste caso, o paciente apresentava infecções/infestações recorrentes, as dosagens de imunoglobulinas encontram-se abaixo do percentil 3 para idade e o de linfócitos B, no limiar mínimo. Reiteramos a importância do diagnostico de ICV em paciente com infecções/infestações recorrentes e esplenomegalia pela importante prevalência na população.
