Causes and prevention of rebleeding after applying super-selective renal arterial embolization for renal danage

Abstract:

Objective：To discuss the etiology and prevention of rebleeding after applying super-selective renal arterial embolization to treat renal injury bleeding． Methods：Clinical data of patients who underwent super-selective renal arterial embolization for renal injury bleeding in our hospital from 2007 to 2012 were collected. Results：There were 22 cases in our hospital，two cases experienced rebleeding after embolization；one stopped bleeding after the second times of super-selective renal arterial embolization with spring coil，the another one stopped bleeding by undergoing nephrectomy. Conclusions：Rebleeding after applying super-selective renal artery embolization to treat renal damage may be caused by renal vascular anatomic or misuse of embolism materials，suggesting that more attention should be paid to these factors to reduce the morbidity of rebleeding.
