Abstract


Introdução: No âmbito da cirurgia cardiovascular, existem algumas técnicas cirúrgicas para a abordagem de doenças que acometam a aorta torácica. Dentre elas, temos a técnica de Frozen Elephant Trunk (FET), que facilita o reparo dessas patologias em uma única etapa cirúrgica.

 Objetivos: Esta revisão tem por objetivo mostrar as indicações, aspectos gerais desta técnica e suas principais complicações.

 Métodos: Trata-se de uma revisão de literatura, onde foram pesquisados artigos sobre a técnica FET. Os dados foram extraídos seguindo critérios de inclusão e exclusão, os quais se direcionavam apenas para a aorta torácica e aspectos da FET.

 Resultados: Dentre as 40 referencias selecionadas, foram identificados 4 estudos mais relevantes sobre o tema, dentre eles 3 metanálises e uma revisão sistemática. Foi identificado um índice de mortalidade que varia de 8.3% a 10.2%, lesão medular que corresponde de 4.1% a 5.1%, acidente vascular encefálico (AVE) de 4.9% a 7.6% e insuficiência renal aguda (IRA) de 9% a 15.5%, respectivamente.

 Conclusão: Conclui-se que de acordo com os resultados analisados nesta revisão, a cirurgia das patologias da aorta torácica que são abordadas pela técnica FET, representam um risco de complicações considerável, incluído o de mortalidade. Viu-se a necessidade de estudos mais robustos sobre o tema.
