Transcatheter Renal Arterial Embolization of a Polycystic Kidney for Control of Persistent Hemorrhage / 대한신장학회잡지

ABSTRACT

We report a patient with autosomal dominant polycystic kidney disease(ADPKD) undergoing maintenance hemodialysis who underwent transcatheter arterial embolization(TAE) of the renal arteries to control the persistent renal hemorrhage. In 1991, the patient had been diagnosed as having ADPKD by computed tomography(CT) of abdomen. In 1997, the patient started hemodialysis. In October 2000, she was admitted to our hospital because of gross hematuria and both flank pain. Abdominal CT showed marked enlargement of the bilateral kidneys with numerous cysts. Renal angiography using the Seldinger technique showed stretched and deformed segmental renal arteries without active bleeding. Renal hemorrhage was continued despite of medical treatment. TAE with stainless steel coils was performed on both renal arteries. Renal bleeding was stopped immediately after TAE and anemia was improved and stabilized thereafter. Follow-up CT after five months later TAE showed the marked decrease in size of both kidneys, and patient's abdominal symptoms were disappeared too. This report shows that TAE is a safe and effective therapy for ADPKD patients with persistent renal bleeding refractory to medical therapy.
