摘　　要：目的通过四肢动脉造影了解血管受损后的形态学改变,指导临床对高压电致肢体血管损伤的范围和程度进行正确估计。方法对17例损伤电压大于380V 电损伤患者进行了26侧29例次选择性动脉造影,观察血管受损后的改变。结果受损的动脉管腔狭窄、闭塞,分支减少或消失;减压术后,部分闭塞的动脉可再通或形成侧支循环。结论动脉造影能观察肢体高压电损伤后的血管改变,对判断动脉受损的范围和程度、指导临床治疗有一定的作用。Objective Because it is difficult to estimate the extent and degree of damage to the blood vessels of extremities sustaining high tension electrical injuries,arteriography was carried out to eval- uate the vascular changes.Methods Selective arteriography was carried out 29 times for 26 extremities in 17 patients suffering from >380V electrical injuries.Results The arteriography showed that the injured arteries were narrowed and occluded,and vascular branches decreased or disappeared.Recanalization of the partially occluded arteries or collateral circulation formation was found after decompression.Conclusion Arteriography is valuable to evaluate the vascular changes in high tension electrical injuries of extremites.
