Use of a micro-balloon catheter in transcatheter arterial embolization of the renal artery for recurrence of symptoms of autosomal dominant polycystic kidney disease

We report a 63-year-old woman who had recurrent symptoms such as remarkable abdominal distension caused by autosomal dominant polycystic kidney disease in spite of previous bilateral renal arterial embolization with microcoils. Renal arterial embolization with trisacryl gelatin microspheres was performed. The embolic agent was infused while the micro-balloon catheter that was coaxially inserted from a 4-F catheter was inflated without any complications. The size of the polycystic kidneys decreased and the symptoms were satisfactorily relieved.
