Session Time: None. Available on demand.
Disclosures: Daniel Moon, MD, MS: Ipsen (Products/Services: No) (Consultant/Advisory Board)
Background and/or Objectives: To describe the utility of beta 2 transferrin (BT) testing in the management of patients using intrathecal drug delivery for either pain or spasticity management.
Design: Retrospective chart review
Setting: Outpatient clinic
Participants: Individuals implanted with intrathecal drug delivery systems who underwent BT testing
Interventions: Interventions: not applicable
Main Outcome Measures: Concordance of BT testing to results of either surgical intervention or CT myelogram.
Results: Sixty individuals with intrathecal delivery systems underwent BT testing as a component of their ongoing management. Twenty-five patients carried a diagnosis of chronic pain and 35 patients carried a diagnosis of severe spasticity. BT testing was done on 56 individuals from the fluid obtained from a catheter access port aspiration and on 4 individuals from the fluid obtained from aspiration of a pump pocket seroma. All individuals subsequently underwent surgical revision or a CT myelogram with dye injection through the catheter access port. Overall concordance was 93%. Three cases of arachnoiditis and one case of subdural encapsulation represented the situations where BT testing was incongruent with either the surgical or CT myelogram result.
Conclusions: BT testing may represent a reasonable technique for troubleshooting individuals with intrathecal delivery systems.
Level of Evidence: Level III
