Arterial embolization for traumatic renal hemorrhage

Objective:To investigate the clinical value of arterial embolization for traumatic renal hemorrhage after invalid conservative treatment.Methods:23 patients of traumatic renal hemorrhage verified by renal artery angiography were treated by super-selective renal artery embolization with gelatin sponge and/or metal coils.Results:Renal bleeding sites of 23 patients could be determined after renal arteriography.Single renal artery bleeding existed in 15 cases,while 2~3 branches of renal artery bleeding in 7 cases.45 coils were implanted.Angiography after embolization showed occlusion of the vessel,contrast agent extravasation and staining disappeared.The clinical symptoms disappeared 1~3 days after embolization.Creatinine and urea nitrogen were within the normal range 2~4 months later.Moreover,renal hypertension didn't happen.Conclusion:Superselective renal artery embolization of traumatic renal hemorrhage is a safe and effective treatment,which has the advantages of little trauma,better effect and fewer complications,and can also maximize the protection of renal function.
