Control of Experimental Traumatic Renal Hemorrhage by Embolization with Autogenous Blood Clot

Abstract

Hemorrhage from artificially produced renal lacerations was controlled by selective arterial embolization with either plain or Amicar-mixed autogenous blood clot in ten dogs. The laceration sites healed as renal scars. Despite the presence of scattered, small renal infarcts caused by the embolization, hypertension did not develop in any dog during the two-month follow-up. No long-term differences could be detected between kidneys embolized with plain or modified clot. Although it is recognized that dogs have a more active fibrinolytic system than humans, the results of this study suggest that selective arterial embolization is a feasible method for controlling renal hemorrhage.
