RESUMO
Abstract Hemodialysis central venous catheter (CVC) insertion can be complicated in patients with anomalous vessel anatomy. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. Central venous placement under ultrasound control has significantly reduced the complications associated with blind puncture and allows an appropriate puncture of the desired vessel, but the CVC can still get misplaced if it follows an anomalous route. Herein, we report a case of dialysis catheter placed into a left sided superior vena cava, only diagnosed after CT scan study.
Resumo A inserção do cateter venoso central (CVC) para hemodiálise pode ser complicada em pacientes com anatomia anômala dos vasos. Nesses casos, o conhecimento detalhado da anatomia do vaso torácico é necessário para identificar a localização exata do cateter. A colocação venosa central sob controle de ultrassom tem reduzido significativamente as complicações associadas à punção às cegas e permite uma punção apropriada do vaso desejado, mas o CVC ainda pode ficar mal posicionado se seguir uma rota anômala. Aqui, relatamos um caso de cateter de diálise colocado em uma veia cava superior esquerda, apenas diagnosticado após estudo de tomografia computadorizada.
