Abstrakt:	Objective: To explore the treatment of multiple or recurrent intracranial tumors by hypodermic placement of Ommaya reservoir and local chemotherapy with methotrexate. Methods: Retrospective analyses were performed on the clinical data of 45 cases with multiple or recurrent intracranial tumors at Friendship Affiliated Hospital, Capital Medical University from January 2010 to September 2013. All 45 cases had a placement of Ommaya reservoir under skin. Shunt tubes were placed in ventricle (n = 41), cystic tumor cavity (n = 3) and tumor cavity (n = 1). Methotrexate was injected postoperatively into Ommaya reservoir by transcutaneous paracentesis. Results: After local chemotherapy, head magnetic resonance imaging (MRI) re-examinations were performed. Tumors disappeared (n = 32), shrunk significantly (n = 10) and had no significant improvement of symptoms with spinal implantation metastasis (n = 1). During chemotherapy, there were two mortalities due to septic shock and heart failure (n = 1 each). Follow-ups were conducted for 32 cases and 7 of them died. One case had operation-related complications. After an adjustment of shunt tube, symptoms and signs improved. And after local chemotherapy, tumor disappeared on MRI. Conclusion: The placement of Ommaya reservoir is mini-invasive and well-tolerated. And local chemotherapy with methotrexate by Ommaya reservoir is convenient and it may reduce systemic side effects, improve the efficacy of chemotherapy drugs, prolong survival time and enhance quality of life.
