Abstract:
Objective To study DSA characteristics of traumatic renal hemorrhage and to discuss the methods for treatment of this disease.Methods Superselective renal arterial angiography was carried in 14 patients with traumatic renal hematuria from 2001~2007.11 cases were iatrogenic renal damage and 3 cases were renal trauma.6 of them were under unstable hemodynamic conditions.Results The bleeding was found in 7 cases,located at the interlobar artery,the branch of segmental artery of the kidney,and the proximal end of arcuate artery.They presented as renal arterial-pelvic fistula(4 cases),arterial venous fistula(1 case) and renal arterial-pelvic fistula with AV fistula(2 cases),2 of them accompanied with pseudoaneurysm.The characteristics on DSA were radiopaque contrast medium overflow rapidly and abundantly,and the lesions were far from peripheral area of kidney,in the other 7 patients,the bleeing arteriae were located at the distal end of arcuate artery and the smaller branches of interlobular artery.The radiopaque material remained in parenchyma of kidney until parenchymal phase.There were no obvious artery-vein fistula or renal arterial-pelvic fistula in all cases.Conclusion DSA examination is very helpful in diagnosis and treatment of traumatic renal hemorrhage.
