Resumo: The anatomy of the cerebral venous system (CVS) is based on a known variable three-dimensional structure. For a correct recognition and characterization of its elements, a detailed knowledge of its anatomy and potential variants is essential However, this structural changes, commonly named as variants, may appear in asymptomatic situations as well as associated to certain pathological syndromes with diagnostic and therapeutic consequences. Purpose: The authors present a brief summary of the CVS anatomy, highlight the potential structural changes and discuss their ethiology as constitutional or pathological. Method and Results: Based on clinical cases, the most frequent anatomical modifications will be presented and their ethiology discussed, whether constitutional or pathological. Conclusion: The CVS is characterized by its various presentations. These changes are classically named as anatomic variants. However, they may appear associated to certain pathological situations. Only a profound recognition of the normal CVS anatomy allows a correct definition of the ethiology of the structural change as constitutional or pathologic.

Para correcta identificação de todos os seus constituintes é essencial conhecer em detalhe os respectivos fundamentos anatómicos e designadas variantes. No entanto, estas alterações estruturais, classicamente denominadas por variantes anatómicas podem surgir, não só em casos assintomáticos, como também em determinadas condições patológicas. Caso em que poderão haver consequentes implicações diagnósticas e terapêuticas. Objectivo: Partindo deste pressuposto, os autores pretendem apresentar uma súmula da anatomia do sistema venoso cerebral e suas eventuais alterações estruturais frisando a sua etiologia simplesmente constitucional ou potencialmente patológica. Método e Resultados: Com base em casos práticos e seguindo uma ordem esquemática e sintética serão apresentadas as alterações anatómicas mais frequentes e discutida a sua etiologia constitucional ou eventualmente patológica. Conclusão: A anatomia venosa intracraniana é caracterizada pela sua ampla variedade de apresentação. Estas alterações são classicamente definidas como variantes anatómicas. No entanto, estas variações podem surgir associadas a determinadas situações patológicas. Apenas um profundo conhecimento das estruturas anatómicas permite caracterizar a etiologia destas diferenças como constitucional ou patológica.Ordem dos Médicos2012-11-02info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/255oai:ojs.www.actamedicaportuguesa.com:article/255Acta Médica Portuguesa; Vol. 25 (2012): Supplement 1; 17-20Acta Médica Portuguesa; Vol. 25 (2012): Suplemento 1; 17-201646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/255https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/255/64Rodrigues Lopes, LeonorPalma, TeresaCravo, IsabelGonçalves, CristinaBousende, MarcoMartins Pisco, Joãoinfo:eu-repo/semantics/openAccess2022-12-20T10:55:54Zoai:ojs.www.actamedicaportuguesa.com:article/255Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:16:23.950880Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
