[The changes in arteriography in extremities sustaining high tension electric injuries]
1Department of Radiology, Second Affiliated Hospital of Kunming Medical College, Kunming, 650101.
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 evaluate the vascular changes.
Methods:
Selective arteriography was carried out 29 times for 26 extremities in 17 patients suffering from > 380 V 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 extremities.
