Contextualização e Objetivo - A frequência e as características da associação entre as FAVd e TVC ainda não são claras. Esta revisão sistemática visa analisar a evidência disponível sobre a relação entre estas condições.
Métodos - Pesquisa sistemática no MEDLINE, desde o início até novembro de 2020, e listas de referência de estudos e artigos de revisão incluídos. Foram considerados estudos observacionais, que relatam dados originais de pacientes com diagnóstico de FAVd e TVC, prévia ou posterior, com um número mínimo de 5 participantes. Foram também incluídos relatos de casos de TVC com desenvolvimento subsequente de FAVd.
Resultados - Foram identificados 699 estudos. Foram incluídos 41, dos quais 24 são séries de casos (1210 pacientes) e 17 relatos de casos (18 pacientes). Nas séries de casos, foi encontrada a presença de FAVd e TVC em 426 participantes (35%). A sequência temporal dos diagnósticos estava estabelecida em 12 pacientes, dos quais 7 tinham o diagnóstico inicial de FAVd seguido de TVC, e 5 tinham TVC como evento inaugural, com identificação de FAVd durante o seguimento. Foram revistos 18 relatos de casos de pacientes que desenvolveram FAVd após o diagnóstico inicial de TVC. O tempo médio entre o diagnóstico de TVC e subsequente FAVd foi de 24 meses. O diagnóstico de FAVd foi estabelecido nos primeiros 6 meses em dois pacientes (12,5%), entre 6 e 12 meses em quatro (25%), entre 12 e 24 meses em seis (37,5%), e após 24 meses em quatro casos (25%).
Conclusões - Os nossos resultados indicam que a FAVd é uma complicação rara da TVC, que ocorre mais frequentemente entre os 6 e 24 meses após o evento trombótico. A escassez de dados sobre esta relação não nos permite concluir com segurança qual dos eventos ocorre, mais frequentemente, como o evento inaugural.
Background and Purpose - The frequency and characteristics of the association between dAVF and CVT are still unclear. This systematic review aims to analyse the available evidence on the relationship between these conditions. Methods - Systematic search in MEDLINE, from inception to November 2020, and reference lists of included studies and review articles. Observational studies were considered, reporting original data from patients with a diagnosis of dAFVs and CVT, prior or later, with a minimum number of 5 patients. Reports of CVT cases with subsequent development of dAVF were also included. Results - 699 studies were identified. 41 were included of which 24 were case series (1210 patients) and 17 were case reports (18 patients). In the selected case series, we found the presence of dAVF and CVT in 426 participants (35%). The temporal relationship of both diagnoses was known in 12 patients, of whom 7 had the initial diagnosis of dAVF followed by CVT, and 5 had CVT as the inaugural event, and identification of dAVF during follow-up. We reviewed 18 case reports of patients who developed dAVF after the initial diagnosis of CVT. The average time period between the diagnosis of CVT and subsequent dAVF was 24 months. A diagnosis of dAVF was made within the first 6 months in two patients (12,5%), between 6 and 12 months in four (25%), between 12 and 24 months in six (37,5%), and after 24 months in four cases (25%). Conclusions - Our results indicate that dAVF is a rare complication of CVT that probably occurs more often from 6 to 24 months after the thrombotic event. The scarcity of data on this relationship does not allow us to safely conclude which of the events occurs, most frequently, as the inaugural event.
