Os aneurismas da aorta abdominal (AAA) constituem uma patologia complexa, com consequências catastróficas se não forem adequadamente diagnosticados e tratados. Atualmente, a reparação de aneurismas endovascular (EVAR) tornou-se numa opção válida de tratamento para os AAA, com melhores resultados peri-operatórios quando comparada com a cirurgia aberta, e está a tornar-se rapidamente na opção preferida pelos pacientes. Contudo, a ocorrência de endoleaks está descrita como o evento adverso mais comum associado ao EVAR. Deste modo, revimos a definição e a classificação dos endoleaks bem como
os seus potenciais riscos e a sua gestão. De acordo com os protocolos atuais de seguimento da Sociedade Europeia de Cirurgia Vascular (ESVS), esta técnica requer um longo seguimento por imagem, habitualmente realizado por angiografia tomográfica computorizada (Angio-TC), o que aumenta os custos e nos leva para a discussão acerca dos riscos da exposição à radiação. Relativamente a este último tópico, revimos também estudos selecionados e concluímos que a angio-TC ao 1º mês é o exame de imagem mais importante para o prognóstico do doente e, se não forem encontradas complicações, podem ser adotadas outras estratégias de seguimento por imagem para minimizar a exposição dos pacientes à radiação e, desta forma, os riscos.
