Abstract:
The rim sign in renovascular compromise may be defined as a thin nephrographic rim outlinning a kidney with another wise faint nephrogram. Renal infarction with gelform and blood clots was induced experimentally in 5 dogsand high dose IVP and CT were performed to evaluate renal cortical rim sign after renal infarction. One expireddue to anesthetic technical failure, and one was embolized partially. So we could be obtain the result on 3 dogs.The reults were as follows; 1. The high dose IVP films show cortical rim sign on 24 hrs and 72 hrs films in twodogs. The CT films show rim sign in 3 dogs. 2. The rim sign may be visualized, if the renal artery is occuludedenough to drop perfusion presssure below the authoregulatory range. 3. The high dose IVP and early nephrogramphase are necessary for the rim sign.
