INNV-11. THE RISK OF HEMORRHAGE ASSOCIATED WITH THROMBOCYTOPENIA IN PATIENTS UNDERGOING OMMAYA RESERVOIR PLACEMENT FOR INTRATHECAL CHEMOTHERAPY: A SINGLE INSTITUTION RETROSPECTIVE ANALYSIS

摘要

Ommaya reservoirs are frequently inserted in patients requiring regular delivery of intrathecal medications. The incidence of intracranial hemorrhage following insertion ranges from 1–3% and is typically associated with thrombocytopenia. However, the exact platelet count at which it is considered safe to insert an Ommaya reservoir has not been previously reported. The purpose of this study is to investigate the nature of the relationship between thrombocytopenia and post-operative hemorrhage following insertion of Ommaya reservoirs for intrathecal chemotherapy.
