Our objective was to review the technical success and clinical outcomes of transcatheter embolization of peripheral renal artery with FuAiLe medical glue (FAL).
All patients who underwent FAL embolization for peripheral renal artery bleeding were retrospectively analyzed for underlying pathologies, technical success and outcome of embolization procedure. 14 consecutive patients underwent FAL embolization between November 2009 and February 2013. The causes of bleeding were post biopsy (n = 5), blunt trauma (n = 5), percutaneous lithotripsy of kidney stones (n = 3), and complication of cardiac catheterization (n = 1). Bleeding was effectively controlled with a single injection of FAL. Mean volume of FAL mixture (FAL:Lipiodol, 1:1) was 0.5 mL (range, 0.2-0.8 mL). No reflux of the embolic agent was noted. Average cost of FAL for each procedure was $74. Postembolization clinical follow-up showed no evidence of recurrent hematuria, progression of hematoma, hypertension, or elevation of serum creatinine. Doppler ultrasound examinations in 13 patients demonstrated no abscess, renal parenchyma infarction, or renal artery abnormalities. Superselective FAL embolization may be used for the treatment of active bleeding from peripheral renal arteries. It has a high success rate and is quicker and less expensive than embolization with other agents.
