AbstractWe report 2 patients for whom anesthetic management using aortic occlusion balloon catheter (AOBC) was performed thrice. A 14-year-old boy and a 43-year-old man with sacral giant cell tumor underwent tumor resection. In both patients, transcatheter arterial embolization (TAE) was performed several times before the operation. Before the surgery, an AOBC was inserted via the right femoral artery. For tumor resection, the AOBC was inflated, and a slight decrease in hemorrhage was observed. The occlusion was maintained for 40-55 min, with a loss of 1,400-3,700 ml of blood. In case 1, moderate bleeding from the epidural venous plexus was observed. In case 2, packed red blood cell transfusion was needed, and the patient returned to surgery for hemostasis. Because the AOBC could not decrease the severity of venous hemorrhage, we expected increased hemorrhage with an increase in the extent of surgery. In addition, preoperative multiple TAE might lead to the development of collateral circulation around the sacrum and augment the amount of blood loss in that region. Although the AOBC could reduce intraoperative hemorrhage, uncontrollable bleeding may occur if the sacral giant cell tumor shows extensive dissemination.
