Endovascular transarterial embolization with liquid embolic agents is the primary modality of treatment of spinal dural arteriovenous fistulae. However, adequate distal percolation of the embolic material may not be achieved in all cases due to varying angiographic characteristics, necessitating further surgical treatment. In such situations, the presence of a retrocorporeal branch of the contralateral radicular artery may provide an alternative route to approach and embolization of the fistula. We describe two cases of treatment failure through the primary arterial feeder that was successful embolized through the retrocorporeal artery. The technical detail of this approach is briefly discussed.
