RENAL artery embolization is a useful preoperative adjunct in the treatment of patients with vascular neoplasms of the kidney. A variety of percutaneous methods have been developed that result in occlusion of renal artery circulation before nephrectomy. A current method of occlusion described by Wallace and co-workers' involves selective placement of stainless steel coils into the renal artery 12 to 24 hours before nephrectomy to decrease operative blood loss.
Migration of occlusive material at the time of insertion has been described; however, to our knowledge, embolization of the occlusive material during subsequent surgery has not been reported. The following report documents migration of occlusive stainless steel coils during nephrectomy resulting in contralateral renal artery occlusion.
Report of a Case
