This case report describes a unique complication following intrathecal baclofen (ITB) therapy for a patient with spinal cord injury (SCI). After revision surgery for a catheter obstruction, the patient's spasticity returned. The issue was found to be a curled-up silicone layer around the sutureless pump connector, causing a malconnection. This specific type of malconnection has not been previously reported. The authors suggest that surgeons should carefully inspect the silicone connector before completing the connection to prevent this complication. Early diagnosis can be challenging, requiring specific imaging techniques.
Surgeons should meticulously inspect the silicone layer of sutureless pump connectors during intrathecal baclofen (ITB) system implantation or revision to ensure proper watertight connection and prevent potential malconnections.
In cases of suspected ITB system malfunction, especially with recurrent spasticity, consider advanced imaging techniques like Indium SPECT-CT when conventional methods are inconclusive.
Be vigilant for signs of ITB system dysfunction, such as recurrent spasticity or CSF leakage, even after seemingly successful revision surgeries.
