THE OMMAYA CATHETER AS A TREATMENT FOR PAIN AND CHEMOTHERAPY IN MENINGEAL CARCINOMATOSIS PATIENT Mariane Ferreira, Eduardo Pessoa Júnior, Caroline Rincolato, Letícia Rigoti, Marina Coronetti, Caio Goulart, Carolina Panis, Carlos Rodrigues Universidade Estadual do Oeste do Paraná, Ccs Centro De Ciências Da Saúde, Francisco Beltrao, Brazil Background and Aims:: Meningeal carcinomatosis consists of focal or multiple malignant metastases of extraneural solid tumors in the leptomeninges and subarachnoid space. It’s a rare complication and neurological symptoms include headache and nonspecific nerve palsy. The standard diagnosis is obtained by the presence of malignant cells in the cerebrospinal fluid cytology. The prognosis is poor, the treatment is limited and aims at palliating symptoms and stabilizing or partial improvement in neurological status. Methods:: This study aims to report a case of treatment for pain and chemotherapy in meningeal carcinomatosis patients by Ommaya catheter use. Results:: Man, 56 years old. Diagnosed 6 months before with intestinal adenocarcinoma, had been treated by surgery, chemotherapy, and radiotherapy. He showed severe pain syndrome, mainly headache, refractory to systemic opioid and non-opioid analgesic therapy. The cerebrospinal fluid cytology confirmed the diagnosis of carcinomatous meningitis. The patient was submitted to palliative treatment with an Ommaya catheter (OC) for intrathecal chemotherapy and opioid analgesic. The OC reservoir was placed under the scalp and attached to a catheter that ends in the lateral cerebral ventricle. Thus, medicines were injected directly into the intracerebroventricular space optimizing the treatment. The Brazilian public health care “Sistema Único de Saúde” (SUS) supported all treatments. Conclusions:: The OC possibility a safe and effective therapy for the palliative treatment of refractory pain at-home care in meningeal carcinomatosis patients, despite this the OC is unusual in Brazil.
