Effectiveness of single-stage shunt replacement for Cutibacterium acnes CSF shunt infection

The findings indicate that one-stage shunt replacement surgery without intervening externalization is an effective treatment option for C. acnes shunt infections. In addition to eliminating the need for multiple surgical interventions, this approach shortens hospital stays, thereby reducing healthcare costs and minimizing patients' exposure to hospital-associated risks. This study supports a reevaluation of current guidelines for treating shunt infections, advocating for more flexible, patient-centered approaches that consider the pathogenicity of offending organisms such as C. acnes.
