Abstract:
Objective:To investigate the clinical value of preoperative selective arterial embolization for spinal tumors.
Methods:The clinical data of 42 consecutive patients who underwent spinal tumor resection in department of orthopedics Shengjing Hospital of China Medical University from January 2017 to December 2018 were retrospectively analyzed. Patients were divided into embolization group (20 cases) and non-embolization group (22 cases) according to whether they underwent arterial embolization before tumor resection. Two surgical treatments including vertebral resection and laminectomy were performed. The embolization group included 12 cases of vertebral resection and 8 cases of laminectomy; while the non-embolization group included 13 cases of vertebral resection and 9 cases of laminectomy. The difference of intraoperative estimated blood loss, total number of transfused packed red blood cell, calibrated estimated blood loss, operation time and hospitalization time were compared using independent sample t test.
Results:Twenty patients in the embolization group underwent successful interventional embolization without serious complications. There were no significant differences between the embolization group and the non-embolization group in terms of intraoperative estimated blood loss, total number of transfused packed red blood cell, calibrated estimated blood loss, operation time, and hospitalization time (P>0.05). Among the patients who underwent vertebral resection, intraoperative estimated blood loss, total number of transfused packed red blood cell and calibrated estimated blood loss were (1 966.7±898.8) ml, (7.42±3.27) U and (91.3±39.2) g/L in the embolization group, and (2 838.5±1 143.5) ml, (11.04±4.08) U and (133.0±46.4) g/L in the non-embolization group, respectively, with statistically significant differences (t=-2.107, -2.436, -2.419, P<0.05). However, there was no significant difference in the operation time and hospitalization time between the two subgroups (t=-0.780, -0.549, P>0.05). Among the patients who underwent laminectomy, there were no significant differences in the above-mentioned indicators between the embolization group and the non-embolization group (P>0.05).
Conclusion:Selective arterial embolization for spinal tumors is a relatively safe interventional procedure. Preoperative embolization does not significantly reduce the amount of blood loss during surgical procedures. After the surgical procedures were differentiated, preoperative embolization significantly reduces the amount of blood loss in patients underwent vertebral resection, while patients who underwent laminectomy do not benefit significantly.
