BACKGROUND:

Evaluating intrathecal baclofen (ITB) delivery systems for potential malfunction can be challenging. The catheter systems are prone to myriad complications that are frequently difficult to ascertain by conventional imaging techniques. Newer imaging technologies and their combinations can be used to identify such problems, define surgical indications, and focus operative planning. C-arm fluoroscopy and C-arm cone beam CT performed in one imaging session represents one such combination that has great utility.

OBJECTIVE:

We present a case series of ITB catheter evaluations using combined C-arm fluoroscopy (CF) and C-arm cone beam CT (CCBCT).

METHODS:

We retrospectively analyzed 7 pediatric patients who underwent ITB catheter systems evaluations by the use of combined CF and CCBCT. Study variables included indications for evaluation, imaging results, interventions, correlation of …
