Spinal Cord Swelling and Alterations in Hydrostatic Pressure After Acute Injury
Abstract
In Year 2 of this award we examined whether duraplasty after acute thoracic spinal cord injury (SCI) in a porcine model could improve long-term functional outcome after injury. We finalized the 12-week PTIBS analysis as well as the somatosensory-evoked potential, which was recorded at baseline, 3 hours post injury and at the final week of the study (12 weeks post SCI). Our data suggest that duraplasty surgery might improve functional recovery early after SCI compared to SCI-animals without duraplasty. In Year 2 we also started surgeries as part of Aim 2 to determine if surgically expanding the subarachnoid space with a duraplasty will alter intraparenchymal spinal cord pressure, SCBF, and metabolic responses; monitored over a 7-day period. During these surgeries, we inserted a total of six probes into the spinal cord in order to be able to measure the blood flow/oxygenation, pressure and microdialysis responses distal proximal (2mm) and (22mm) to the impact site. The data are too preliminary for one to draw firm conclusions. Additional surgeries will be performed in YEAR 3 of the grant.
