The goal of treatment for spinal arteriovenous lesions is to completely obliterate the shunt. In our institution, intraoperative digital subtraction angiography and intraarterial injection of contrast agent have been used to accurately identify the site of arteriovenous shunts. We describe the intraoperative digital subtraction angiography and intraarterial dye injection procedures and how they may improve surgical outcomes. ⋯ Intraoperative digital subtraction angiography and intraarterial dye injection are useful tools for management of spinal arteriovenous lesions.
