[Intrathecal baclofen therapy for spastic paraparesis due to aortic dissecting aneurysm; recent progress in treatment...

A 48-year-old man suffered from acute dissection of thoracic aortic aneurysm which eventually led to replacement of the ascending aorta with a tube graft. During this clinical course, circulatory failure in intercostal artery resulted in spinal cord infarction followed by moto-sensory disturbance below Th7 dermatomic area. Seven months later, spasticity with pain in both lower extremities became conspicuous that was uncontrollable by any oral medication. Eventually the patient underwent the implantation of continuous infusion pump for intrathecal baclofen therapy (ITB). The clinical condition was remarkably improved and now has been well controlled. ITB, authorized by Japanese Ministry of Health Labour and Welfare in 2006, has notable therapeutic effects on spasticity derived from any sort of central nervous disorder. More promotive enlightenment if ITB is indispensable for enhancement of its medical benefit in Japan.
