Abstract:
Objective To investigate the relationship between the different embolization agent and the spinal cord ischemic injury. Methods Bilateral of intercostal arteries were embolized with gelatin sponge and lipiodol to block the blood supply of spinal cord. To detect the somatosensory evoked potentials(SEPs), 6 canines in both groups of gelatin sponge and lipiodol were treated by bilateral intercostal arteries embolization. The median nerve and fibular nerve were recorded and the ratio of lower extremity to upper extremity SEPs amplitude (LE/UE ratio) were calculated; the results were compared with the pathologic findings and the motor function. Results The baseline, LE/UE, evoked potential amplitude ratios in all dogs before operation ranged from 0.22 to 0.92 with a combined total mean of 0.49?0.07. The SEPs changes at 30 minutes post operation were more obvious than pre operation in gelatin sponge group and lipiodol group with statistic significance. The LE/UE ratio of gelatin sponge group recovered one hour after operation, but this was absent in lipiodol group. So did the latency SEPs changes. Conclusion The SEPs could not be used to evaluate the motor function of spinal cord comprehensively.
