Abstract
Spinal cord stimulation (SCS) interferes with cerebral blood flow (CBF). In this paper we try to evaluate the possible preventing effect of SCS in an animal model of combined ischemic and traumatic injury. We studied 20 New Zealand rabbits undergoing ligature of both carotid arteries and a right hemispheric craniectomy and about 3 h mechanical injury (200 mg) over the dura. In 10 animals (control group) SCS was not delivered; in 10 (SCS group) cervical SCS was started 20 min after arterial ligation and before the craniectomy and the mechanical injury. MR examination was performed in all the animals at the end of the experiments. Compared to the control group none but one of the SCS showed lesional pattern far from the craniectomy suggesting a ‘preventing’ effect of SCS on the secondary damage associated with our model combined ischemic and traumatic brain injury.
