Abstract
Renal artery embolization has become one of the more common vascular interventions of the kidney second only to renal artery angioplasty. Indications for embolizatin include control of bleeding due to trauma, obliteration of abnormal arteriovenous communications, tumor devascularization, obliteration of aneurysms and pseudoaneurysms, medical nephrectomy, and accessory renal artery embolization before abdominal aortic aneurysm stent graft repair. Various embolic agents are available depending on the rationale for embolization and physician preference. Selective cannulation of the involved vessel is preferred to spare as much renal parenchyma from devascularization as possible.
