Background:
To explore the effect of tranexamic acid (TXA) on perioperative blood loss in posterior decompression surgery of patient with metastatic spinal tumor.
Methods:
Three hundred sixty-eight consecutive patients between May 2011 and Aug 2022 were retrospectively reviewed. One hundred eighty patients (182 surgeries) met the criteria and were included in the study. Sixty-two surgeries received preoperative intravenous TXA (TXA group), and 120 did not (non-TXA group). The primary outcome was total blood loss. T-test, Mann-Whitney U, and chi-square tests were used to evaluate the difference in baseline data, total blood loss, and other outcome measures between the two groups.
Results:
Patients with hyper vascular tumors had significantly more blood loss compared with non-hyper vascular tumors (2002(1531,2792) mL vs 1469(1036,1962) mL, p=0.001). There was no significant different in the postoperative venous thromboembolism of the lower limb between the two groups. For patients with non-hyper vascular tumors, the blood loss (1216(827, 1709) mL vs 1561(1146, 2019) mL, p = 0.012) and postoperative drainage (1-day post-operation: 240(150,290) mL vs 280(150,395) mL, p=0.040; 3-days post-operation: 450(348,630) mL vs 613(398,799) mL, p=0.025) of TXA group were significantly less compared with that of the non-TXA group. Meanwhile, the TXA group had significantly less postoperative hospitalization compared with the non-TXA group (11.0(9.0, 13.3) days vs 12.5(9.0, 16.3) days, p=0.023). For patients with hyper vascular tumors, there were no significant differences in the blood loss and amount of postoperative drainage between the two groups.
Conclusion:
Preoperative intravenous TXA demonstrated a trend toward decreased perioperative blood loss in posterior decompression surgery of spinal metastases with non-hyper vascular tumors.
