Popis: Objective Thoracic spinal stenosis (TSS) surgeries necessitate a substantial amount of allogeneic blood resources. However, the efficacy of preoperative autologous blood donation (PABD) in TSS surgery has not been clearly evaluated. Therefore, we aimed to evaluate the efficacy of PABD for TSS surgery. Methods This study is a retrospective study. Totally 397 patients who underwent TSS surgeries at our institution from January 2019 to June 2023 were included. Propensity score matching (PSM) was used to make the PABD and Non‐PABD groups comparable at baseline. Regarding outcome measures, the incidence and amount of allogeneic blood transfusion, changes in postoperative hemoglobin and hematocrit levels, occurrence of postoperative complications, medical costs, drainage time, length of hospital stay, and postoperative neurological function were analyzed. The outcomes were compared between the matched PABD (n = 79) and Non‐PABD (n = 79) groups. Univariate analysis methods were used for statistical analysis, including independent samples t‐test, Wilcoxon rank‐sum test, and chi‐square test. Results The incidence of allogeneic blood transfusion (8.9% vs. 25.3%, p = 0.006) and volume of intraoperative red blood cell (RBC) transfusion (10.12 ± 54.52 vs. 122.78 ± 275.00 mL, p
