[Fluorescein aspiration during induction of anaesthesia : complication preceding surgical treatment of cerebrospinal fluid fistula].

This case history deals with an 85-year-old patient who underwent surgery to treat rhinoliquorrhea. The patient aspirated a lutescent fluid shortly after anesthesia was administered. However, this fluid was not gastric juice but cerebrospinal fluid (CSF) running down the nasopharynx. The CSF had been stained with fluorescein prior to surgery in order to help localize the CSF fistula. This case of top down aspiration is discussed and preventive measures which can be employed in order to avoid similar complications in patients with rhinoliquorrhea are presented.
