The authors review the anatomy of the middle sacral artery and its relationship to the lower lumbar and internal iliac arteries. Middle sacral arteriography was performed in 8 patients, transcatheter tumor embolization in 6, and infusion chemotherapy in 1. There were no complications. The authors consider selective middle sacral arteriography beneficial in the diagnosis and treatment of sacral tumors.
