Blood loss and perioperative transfusions related to surgery for spinal tumors. Relevance of tranexamic acid.
Tranexamic acid (TXA) has been shown to reduce bleeding. Patients with spinal tumors are fragile and acute anemia may be harmful. Tumor excision surgery is reputed to be hemorrhagic and treatment may increase thromboembolic complications. The aim of this study was to compare blood loss with or without perioperative TXA injection. The transfusion-related and postoperative complications were documents. This retrospective analysis of prospectively collected data involved 83 patients with spinal tumors who underwent decompressive surgery associated with bone fixation. Tranexamic acid was used arbitrarily in 36 of them, while the other 47 did not receive TXA. The overall, intraoperative and postoperative blood loss was recorded. Blood loss was reported relative to the number of fixed levels and the number of levels decompressed by laminectomy. Transfusions were quantified in number of red blood cell packets and erythrocyte volume. Postoperative complications were documented. Epidemiological and morphological data were similar between groups. There were no significant differences between the two groups in the overall, intraoperative, and postoperative blood loss. A significant reduction in postoperative bleeding was found in the TXA group when the volume was related to the number of decompressed levels. A significant reduction (P<0.05) in the volume of transfused blood was identified in the treated group. No predictor of blood loss was identified, and no additional complications occurred. The efficacy of TXA appears to be moderate during spinal tumor surgery since it does not lead to a reduction in perioperative bleeding. However, a significant reduction in transfusion volume was found without an increase in complications.
