脊髓功能诱发试验在支气管动脉介入治疗中的应用

The using of the spinal cord function inducing test in bronchial artery interventional technology

目的:探讨利多卡因脊髓功能诱发试验在支气管动脉介入治疗术中预防脊髓损伤的作用.方法:常规治疗组肺癌采用支气管动脉灌注化疗术或加栓塞术,大咯血采用支气管动脉栓塞术;利多卡因诱发试验组常规化疗栓塞术同前,术前加用利多卡因脊髓功能诱发试验,即动脉内缓慢注入1%利多卡因3～5ml,判断支气管肋间动脉干有无合并根动脉,阳性者行微导管超选择插管治疗.结果:常规治疗组464例,发生脊髓损伤致瘫6例,占1.3%,利多卡因诱发试验组21 5例,行诱发试验116例,阳性者37例,无1例患者出现截瘫.两组差异显著(P＜0.05) .结论:介入治疗前应用利多卡因脊髓功能诱发试验判断支气管动脉有无合并脊髓根动脉,能有效避免髓动脉损伤致瘫痪的发生.

Objective：To research the prevention of spinal cord injury of bronchial arteries interventional technology by lidecaine reducing test.Methods： Selective bronchial arteries interventional treatment was performedin 679 cases from 1991 to 2004. Lidecainc in- ducing test was performed before the bronchial arteries intervenfional technology since 2000, injected about 3 - 5ml 1% lidecaine into the bronchial-intercostal arteries, positive result indicated to choice SP-catheter for the further entrance to the bronchial arteries. Results： No spinal cord injury cases had been found in the group of having inducing test before the interventional therapy,which about 37 cases have positive test result. Conclusion： Lidecaine inducing test judge the bronchial-intercostal arterious had the radicle artery or not, which can reduce the rate of spinal cord injury in bronchial arteries interventional therapy.
