[Computed tomography guided percutaneous aspiration and drainage of thoracic and abdominal fluid collections (author's transl)].

Computed tomography can be of value in guiding percutaneous aspiration and drainage of thoracic and abdominal fluid collections of various origins and localizations. Puncture-aspiration is of diagnostic importance when computed tomography findings are non-pathognomonic. Techniques employed for percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage of infected fluid are described. Puncture-aspirations and percutaneous drainage under computed tomography guidance are free from major complications, and represent a more valid therapeutic method than surgery, being simpler to perform and supplying identical results.
