Renal Artery Embolization in Patients with Polycystic Kidney Disease

Abstract

Polycystic kidney disease (PCKD) is the most common life-threatening genetic disease that causes kidney failure worldwide. Patients with autosomal dominant PCKD notice an increase in abdominal size as the kidney cysts grow and present with gastrointestinal and pulmonary symptoms. Surgical therapy, percutaneous drainage, sclerotherapy, cyst decompression, and laparoscopic fenestration have been used to treat the symptoms, but the results are often unsatisfactory. We recruited five patients with PCKD. Each patient complained of severe abdominal discomfort, and had a poor quality of life. In these patients, we performed renal artery embolization. After the procedure, all of the patients were discharged without severe complications. Follow-up abdominal computed tomography was performed 3-6 months after the procedure, and we were able to confirm a reduction in the size of both kidneys. In addition, the clinical symptoms improved in all five patients.
