创伤性上升性脊髓缺血损伤

脊椎损伤后,脊髓损伤平面上升较为少见。作者报告了５例,其中Ｔ１０－１１骨折脱位２例：１例于伤后２周内,截竣平面上升至Ｃ２,呼吸麻痹死亡,１例上升至颈部脊髓,双上肢无力;另３例为Ｔ１２骨折２例,Ｌ３骨折１例：其中截竣平面上升至Ｔ９至１例,Ｔ８者２例。５例患者双下肢皆呈软竣,１例死亡患者尸检见脊髓完整,Ｔ９－１０段脊髓前后动静脉血栓,其向上至Ｃ３,向下至Ｓ１,脊髓前血管、中央血管、髓内小血管多处 栓,

Traumatic ascending ischemic injury of the spinal cord

We report five cases that the paraplegic level showed ascending from the segment of spinal injury upward to the higher level.In T 10 11 fracture dislocation,the paraplegic level ascended gradually to C 2 3 in case 1 within 10 days and death due to breathing paralysis. In case 2,the paraplegic level ascended to cervical cord with loss of strength in both arms within 14 days.The remaining 3 cases were T 12(in 2 cases) and L 3(1 case) fracture.Their paraplegic level ascended to T 8(2 cases) and T 9(1 case).There were lower motor neuron paralysis in all cases.Observation on spinal cord specimen of case 1 showed thrombosis of dorsal vessels at T 9 10 segment and multiple thrombosis were found in anterior spinal vessels, central spinal vessels and intramedullar small vessels upward to C 3 and downward to S 1 segments. The whole cord underwent ischemic necrosis.
