Fatality resulting from intraventricular vincristine administration.
BACKGROUND
Inadvertent intrathecal administration of vincristine has been reported and is uniformly fatal except in two of three cases treated with spinal fluid exchange. We report a case of inadvertent direct intraventricular vincristine administration.


METHODS
A 59-year-old woman developed acute lymphocytic leukemia with meningeal involvement and was being treated with intraventricular cytarabine (beta-cytosine arabinoside, Ara-C) injected via an Ommaya reservoir, intravenous (i.v.) vincristine, prednisone, and i.v. daunorubicin. The vincristine (2 mg in 10 mL diluent) was inadvertently injected into her Ommaya reservoir. Within 10 minutes, the error was realized. Despite optimal care, nausea and vomiting developed the first night, followed sequentially by coarse tremor, disorientation, horizontal nystagmus, and stupor. Her mental status waxed and waned until day 9, at which time she became responsive only to noxious stimuli. By day 11, she was deeply comatose and on day 40 she died without regaining any neurological function.


CONCLUSIONS
Despite aggressive and immediate therapy, intraventricular vincristine infusion produced neurologic toxicity, with progressive loss of mental function, followed by coma and death. Systems need to be developed to prevent inadvertent central nervous system administrations.
