Device for spasticity…

Abdomen/Pelvis, CT, Devices, Non-Trauma


Here is a CT (with scout film) showing a not-to-uncommon device placed in the abdominal wall:

Baclofen 1 Baclofen 2 Baclofen 3

This is an example of an intrathecal pump, commonly used to deliver baclofen.  The first image shows the pump tubing coursing on the abdominal wall, into the thecal space (inserting just lateral to the spinous process of the lumbar vertebrae).  The second image shows a crossection where the pump is located in the abdominal musculature.  The scout film gives you a good idea how big these pumps are.  They have a reservoir port for percutaneous refilling of the baclofen and they can be interrogated for functioning and changing settings. 

Complications of these can include pump failure, baclofen running empty, tubing kink or breakage, and infection/hematoma, and a cerebrospinal fluid leak at the site of insertion.
