    Abstract:
    BACKGROUND: Hydrocephalus associated with intracranial germ cell tumors or disseminated medulloblastoma has been treated with ventriculoperitoneal shunt. However, this procedure has a potential risk of intraperitoneal metastasis of these brain tumors. To prevent this potential risk and to minimize the risk of infection, we developed a percutaneous long-tunneled ventricular drainage (PLTVD). To confirm the effectiveness, we retrospectively analyzed the results of this procedure. METHODS: From 1979 to 2003, we have treated 96 patients with germ cell tumors and medulloblastoma in our hospital. Of 96 patients, 59 (germ cell tumor, 31; medulloblastoma, 28) had hydrocephalus and 13 needed long-term cerebrospinal fluid drainage to manage the obstructive hydrocephalus due to persistent tumor or communicating hydrocephalus due to dissemination. We performed PLTVD for these cases using a flow-controlled shunt device and percutaneous long-tunneled shunt tube (peritoneal catheter) exiting at the upper abdomen and connecting to a closed drainage system. The occurrence of extraneural metastasis and the incidence of infection were evaluated. RESULTS: The average duration of drainage was 74 days (range, 34-115 days). All 13 cases received full-dose chemotherapy and radiotherapy without infectious complications or extraneural metastasis. CONCLUSIONS: Percutaneous long-tunneled ventricular drainage was an effective method to manage long-lasting obstructive or communicating hydrocephalus with germ cell tumors and medulloblastoma.
