Acute renal artery occlusion is a rare but threatening problem; optimal therapeutic treatment remains a challenge, and ultimate outcomes are still to be defined. In the last decades, several reports or short-case experiences have been reported describing the use of selective infusion of lytic agents into renal artery to treat acute occlusion. We report 4 cases of acute renal artery occlusion treated by catheter-directed intraarterial thrombolysis.
