2:34 PM Abstract No. 158 - Emergency endovascular superselective embolization of traumatic and iatrogenic renal artery pseudoaneurysms with fuaile medical adhesive (α-cyanoacrylate)

Abstract

Purpose The aim of this study is to report the effectiveness of selective endovascular embolization with FuAiLe(FAL) medical adhesive (α-cyanoacrylate) in the treatment of traumatic and iatrogenic renal arterial pseudoaneurysms. Materials and Methods Retrospective study of patients with pseudoaneurysms treated with FAL over a 3-year period was conducted. 12 consecutive patients were evaluated, including 4 women and 8 men ranging in age from 16 to 62 years (mean, 45.2y). Causes included renal biopsy (n = 4), percutaneous renal lithotripsy (n = 3), renal trauma (n = 4), and guidewire stabbed renal artery branch in cardioangiography procedural (n = 1). FAL was the only embolic agent used in all patients. FAL was mixed with iodized oil in a 1:1 ratio to control its polymerization time and to make it radiopaque. Diagnostic angiography and superselective embolization were performed at the same session. 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. Conclusion The endovascular management of renal artery branch pseudoaneurysms by superselective embolization with FuAiLe medical adhesive (α-cyanoacrylate) is a reasonable and an effective therapeutic technique.
