Minimizing bleeding complications in spinal tumor surgery with preoperative Onyx embolization via dual-lumen balloon catheter

摘要

Background Intraoperative bleeding is a significant risk in surgery for highly vascular spinal tumors, but preoperative embolization can safely decrease intraoperative blood loss in extrinsic spine tumors. Onyx, widely used for cerebrovascular embolization, has been increasingly used as an embolic agent for preoperative spinal tumor embolization. The Scepter catheter, a dual lumen balloon catheter, may improve tumor parenchymal penetration without the danger and limitations of significant embolic reflux. This may reduce bleeding risk during spinal surgery.
