We report a case of huge renal arteriovenous aneurysm, which was successfully treated with transcatheter arterial embolization (TAE). A 72-year-old woman was admitted with the clinical symptom of dyspnea on effort. She felt a tremor in the left abdomen. Computerized tomographic scan showed a large enhanced mass (8x7x7 cm) on the left kidney. Selective renal arteriography revealed a renal arteriovenous aneurysm. Transcatheter arterial embolization with a steel coil was performed with minimal loss of renal parenchyma. A total of 270 cases of arteriovenous fistula have been reported in Japan and were statistically analyzed. The number of reports on TAE has dramatically increased since 1978, TAE can be first indicated for treatment of renal arteriovenous fistula in view of less invasiveness and preservation of renal function.
