Abstract
Five patients, four male and one female aged 17–65 years (mean 41 years), with iatrogenic renal vascular lesions were treated by percutaneous artenial embolisation. Vascular trauma was caused by percutaneous biopsy (two cases), percutaneous nephrolithotomy (one case), partial nephrectomy (one case) and total nephrectomy (one case). Recurrent macroscopic haematuria was present in four cases and congestive cardiac failure due to reno-caval shunt in one case. Selective renal arteriography revealed false aneurysm in all cases, associated with arteriovenous fistula in four cases. Treatment was performed by selective embolisation of the injured artery. Coils and n-butyl-2-cyanoacrylate mixed with iodised oil or tantalum powder were used as embolic agents. Two patients required two embolisation procedures for definitive treatment. No complication was observed.
