[Intrathecal Baclofen Therapy for Spastic Paralysis].

Abstract

Intrathecal baclofen therapy(ITB)is a recognized treatment for spastic paralysis. Direct injection of baclofen into the intrathecal space through a catheter from a battery-loaded pump implanted in the abdomen allows effective administration of the drug at much lower doses than oral administration. ITB therapy is indicated for patients with severe spastic paraparesis that do not respond sufficiently to first-line medical therapy or in whom the side effects complicate treatment. A pump implantation is considered in cases where spasticity is improved after intrathecal infection of a small amount of baclofen. Postoperative complications include CSF leakage, infection and device malfunction. Postoperatively, the patient requires baclofen refills every 2-3 months and pump replacement surgery every 6-7 years. Currently, ITB therapy is not widespread in Japan, although further popularization is expected.
