Résumé : We describe the case of a woman with ventriculo-peritoneal drainage who presented, following bilateral breast reparative surgery, an abnormally abundant liquid production in one of the surgical drains. This production was related to unknown rupture of the thoracic portion of the ventriculo-peritoneal drain, having led to the direct passage of the cerebrospinal fluid into the surgical drain. Rupture of the thoracic portion of the ventriculo-peritoneal drain was demonstrated by X-ray. However, the pathway of the cerebrospinal fluid and its direct passage throughout the surgical drain were demonstrated by isotopic procedure. Based upon this observation, we briefly describe and discuss the principle, technical characteristics, advantages and disadvantages of isotopic procedures, allowing to demonstrate permeability of ventricular derivations. © 2007 Elsevier Masson SAS.
