RESUMO
Resumo As lesões iatrogênicas das vias biliares são relativamente frequentes e aumentam as taxas de morbidade e mortalidade pós- operatória. A colangiografia por ressonância magnética ponderada em T2 e as imagens hepatobiliares funcionais com ácido gadoxético (CRM-F) são fundamentais na abordagem diagnóstica desses pacientes. Os autores apresentam uma revisão da literatura e sugerem uma manejo radiológico da lesão do trato biliar, demonstrando, por meio de casos clínicos, como a CRM-F pode contribuir no processo de tomada de decisão no manejo desses pacientes.Abstract Iatrogenic lesion of the bile ducts is a relatively common occurrence during liver surgery, increasing morbidity and mortality rates. T2-weighted magnetic resonance cholangiography and gadoxetic acid-enhanced functional magnetic resonance cholangiography (fMRC) with administration of hepatobiliary-specific contrast medium (gadoxetic acid) are fundamental to the diagnostic imaging approach in patients with such lesions. Here, we present a review of the literature and suggest an imaging approach to biliary tract injury, focusing on clinical cases in which fMRC had an impact on the decision-making process for the management of the affected patients.
