Superselective renal artery embolization for the treatment of traumatic renal hemorrhage / 介入放射学杂志

ABSTRACT

Objective To assess the value of transcatheter superselective arterial embolization in treatment of renal traumatic hemorrhage. Methods 20 patients underwent digital subtraction angiography with definite diagnosis before embolization. Embolization materials used in the study were gelfoam sponge chips and steel coils including 14 cases of segmental arteries with their branches through superselective renal arterial embolization. 6 cases were treated by selective renal arterial embolization. Results After renal artery embolization, macroscopic hematurin disappeared on 3th to 5th day after the procedure. With an average of 29 months of follow-up, there was no recurrent hemorrhage associated with normal renal function and blood pressure. Conclusions Superselective renal arterial embolization has advantages of less aggression, less complications, and good hemostatic efficacy, with maximal preservation of renal tissue and function for treatment of mild and moderate renal injuries.
