Chordoma is known to be the most common primary tumor of the sacrum. Its surgery is challenging from many aspects. A large amount of bleeding is one of the biggest issues. A 52-year-old woman was admitted to our clinic with a huge mass at sacrum. The mass was diagnosed as chordoma after a needle biopsy. Prior to the surgery, a balloon dilation catheter (BDC) was placed in the distal abdominal aorta via the femoral artery. Just after the skin incision, the BDC was inflated with contrast medium and total occlusion of the aorta was achieved. At the end of the operation we observed that total hemorrhage had decreased dramatically. No complications were recorded except hypertension during the occlusion of the aorta which was expected. The patient was discharged after two weeks of hospitalization post-operatively without any neurological deficit. Our report is the second in the neurosurgical literature to our knowledge. Although this result is preliminary and needs to be replicated and expanded upon, our first experience with this method is effective for decreasing the amount of bleeding. We believe that our method prevents hemo-dynamical problems caused by massive bleeding and complications secondary to massive transfusion.
