Effects of intraarterial injection of contrast medium on regional circulation in soft tissue trauma.

The effects of repeated intraarterial injections of methylglucamine metrizoate on regional circulation were registered in soft tissue trauma to the dog hind leg. The circulatory disturbances were determined by hemodynamic measurements and by angiography. The changes of flow following injection of the contrast medium were related to the films. The informative arterial phase appeared in the time lag between injection and the flow increasing effect of the contrast medium both before and after trauma. No evidence of a cumulative effect was recorded.
