Resumo

A instalação percutânea dos filtros de veia cava inferior é realizada, tradicionalmente, em sala de angiografia ou em centro cirúrgico, utilizando-se fluoroscopia e infusão de contraste iodado para adequado posicionamento do dispositivo. Porém, para pacientes internados em unidades de tratamento intensivo com condição clínica ruim para o transporte ou com função renal deteriorada, o deslocamento e a nefrotoxicidade dos contrastes iodados são, freqüentemente, motivos de preocupação. Assim, a colocação, à beira do leito, de filtros de veia cava inferior guiada por ultra-som pode ser uma alternativa bastante atraente e segura para esses pacientes.

Abstract

The percutaneous placement of inferior vena cava filters is traditionally carried out in angiosuite or operating room using fluoroscopy and infusion of iodinated contrast for proper positioning of the device. However, for patients hospitalized in intensive care units under poor conditions for transportation, and for patients with impaired renal function, their displacement and the nephrotoxicity of the iodinated contrast agents are frequently matters of concern. Thus, the bedside placement of inferior vena cava filters guided by ultrasound may be a reasonably safe and attractive alternative for these patients.
