Simultaneous transarterial and transvenous coil embolization for a large aneurysmal-type renal arteriovenous fistula

摘要

A 74-year-old woman underwent abdominal computed tomography for screening, and a right large aneurysmal-type renal arteriovenous fistula (AVF) was found incidentally. The venous sac of the renal arteriovenous fistula was enlarged, and coil embolization was considered. To prevent severe complications such as coil migration, pulmonary embolism, and rupture during procedure, coil embolization was approached via both the feeding artery and the draining vein simultaneously, with balloon occlusion of the feeding artery. It was accomplished successfully, and the patient could discharge without complication.
