RESUMO
This animal experiment was in succession to the research on paraplegia caused by spinal cord local ischemia in an animal model. Immediately after the operative production of local spinal cord ischemia, pedicled omentum spinal transposition onto the ischemic segments of spinal cord was performed. The animals recovered from paraplegia around two months afterwards. Spinal cord specimens showed adhesion of omentum to the spinal cord without compression. Omental vessels grew into the cord. Gross sections of specimen stained with Nissl method revealed that normal structure of nerve cells were preserved but number of nerve cell decreased.

Local spinal cord ischemia model was established in 11 adult dogs. The anterior spinal artery, posterior spinal artery and radicular artery were cauterized with bipolar cautery. Ischemia of this segment of spinal cord was thus produced followed by paraplegia. The pathological findings of this spinal cord segment were softening and necrosis. The establishment of this animal model of segmental spinal cord ischemia is beneficial to scientific research in basic medicine and clinical practice.
