OBJECTIVE The aim of this study is to report the effectiveness of selective endovascular embolization with N-butyl cyanoacrylate (NBCA) in the treatment of traumatic intrarenal arterial pseudoaneurysms. METHODS Five patients (four males and one female) presented with massive haematuria. Five pseudoaneurysms were detected angiographically, and in all of the cases the aetiology was penetrating trauma. The pseudoaneurysms ranged in size between 7 and 30 mm (mean: 13.8 mm). After the superselective catheterization with a microcatheter-microguidewire system, embolization was performed using NBCA and Lipiodol mixture. RESULTS All the pseudoaneurysms were successfully embolized and excluded from the circulation without any other major intrarenal arterial branch occlusion. There were no major or minor complications related to the embolization procedures. Haematuria ceased in 1-3 days after the embolization, and during the follow-up period both re-bleeding and deterioration of renal function did not occur. CONCLUSIONS The endovascular management of renal artery branch pseudoaneurysms by embolization with NBCA is a reasonable and an effective therapeutic technique.
