Abstract: Objective To investigate the clinical application value of preoperative interventional arterial embolization in total en⁃bloc spondylectomy (TES) for spinal tumors. Methods The clinical data of 34 patients who underwent TES for spinal tumors in the department of Orthopaedic Soft Tissue Surgery of the Guangxi Medical University Cancer Hospital from January 2023 to June 2024 were retrospectively analyzed. The patients were divided into the embolized group (n=11) and the non⁃embolized group (n=23) based on whether underwent preoperative interventional arterial embolization. The differences between the two groups were compared in terms of intraoperative blood loss, red blood cell transfusion volume, calculated blood loss, operative time and length of hospital stay. Results Interventional arterial embolization was successfully performed in all 11 patients in the embolization group, with no serious complications reported. The intraoperative blood loss in the embolized group was 900.00 mL, the red blood cell transfusion volume was 4.00 U, the calculated blood loss was 55.00 g/L, the operative time was (340.91±100.84) min, and the length of hospital stay was (14.18±3.76) days. In the non⁃embolized group, the corresponding values were 1,200.00 mL、3.50 U、63.00g/L、(313.48±72.21) min and (16.26±5.11) d, respectively. There were no statistically significant differences in above indexes between the two groups (all P>0.05). Conclusions Preoperative interventional arterial embolization in TES for spinal tumors are relatively safe. It may still offer potential advantages in reducing intraoperative blood and the risk of major bleeding.
