Use of a fractional drainage system (an Ommaya reservoir) in the multimodality treatment of patients with the cystic form of cerebral metastases
Surgical treatment for brain metastases in current clinical oncology requires the involvement of radically new approaches that frequently differ from classic neurosurgical standards. The pattern of cerebral metastases is diverse, which governs various surgical approaches during their removal. Cerebral metastases have a pronounced cystic component in 15 % of cases (according to the data of the Russian Cancer Research Center). The application of an Ommaya reservoir has an advantage over open removal of metastases with a pronounced cystic component and permits drainage of a cystic metastasis even if located in the functionally relevant areas.
