Spinal cord infarction is extremely rare in children, and, similar to cerebrovascular infarcts, the pathogenesis is different from adults. Spinal cord infarcts are most commonly reported in adults in the context of aortic surgery; in children, the etiology is frequently unknown. Fibrocartilaginous embolization is a potential cause of spinal cord infarct in both populations. It is a process that...

STUDY DESIGN The effect of edaravone, a novel free radical scavenger, was assessed functionally and histologically using a rat spinal cord contusion model. OBJECTIVE To investigate the effect of edaravone on neuroprotection after spinal cord injury in rats. SUMMARY OF BACKGROUND DATA The spinal cord injury results in immediate physical damage (primary injury), followed by a prolonged neural...

Ischemic preconditioning has been reported to protect against spinal cord ischemia-reperfusion (I-R) injury, but the underlying mechanisms are not fully understood. To investigate this, Japanese white rabbits underwent I-R (30 min aortic occlusion followed by reperfusion), ischemic preconditioning (three cycles of 5 min aortic occlusion plus 5 min reperfusion) followed by I-R, or sham surgery. ...

The present study aimed to determine the occurrence of autophagy following ischemia/reperfusion (I/R) injury in the rat spinal cord and whether autophagy inhibition contributes to neural tissue damage and locomotor impairment. A spinal cord I/R model was induced via descending thoracic aorta occlusion for 10 min using systemic hypotension (40 mmHg) in adult male Sprague-Dawley rats. Then, 600 n...

OBJECTIVE In our experimental study, we aimed to test the effect of FK506, azathioprine and L-carnitine on protection of spinal cord injury due to ischemia-reperfusion. METHODS Twenty-seven Sprague-Dawley male rats were randomly divided into five groups. They were subjected to spinal cord ischemia by clamping the abdominal aorta for 45 min. Thirty minutes before the aortic clamping, group I r...

Nogo receptor-1 (NgR1) and its ligands inhibit neuronal plasticity and limit functional recovery after brain damage such as ischemic stroke. We have previously shown that lateral olfactory tract usher substance (LOTUS) antagonizes NgR1-mediated signaling. Here, we investigated whether LOTUS enhances neuronal plasticity and functional recovery after brain focal ischemia in adult mice. Focal isch...

Ischemia-induced lipid peroxidation is one of the most important factors produdng tissue damage in spinal cord injury. In this study a standard spinal cord injury model in rats was used and the effects of chronic administration of Selenium (3ppm/lt water orally) before and alpha-tocopherol management (100 mg/kg. intraperitoneally) just after the trauma were investigated. For this purpose animal...

This report describes the development of recurrent spinal cord ischemia in a patient after insertion of a stent graft into the upper segment of the descending thoracic aorta for the treatment of a chronic traumatic aneurysm of the aortic isthmus. Intraoperatively, the stent covered the ostium of the left T7 artery, which was shown to give rise to a middle dorsal artery by postoperative spinal c...
