Objective: Embolization for blood-rich brain tumors (tumor embolization) is widely performed before excision as a useful adjunct therapy for reducing the intraoperative bleeding and tumor softening. However, the patient may develop fever after tumor embolization; this complicates the systemic management during the perioperative period. Therefore, we analyzed the changes in the body temperature of patients with meningioma who underwent resection at our hospital.
Methods: We enrolled 38 meningioma patients who underwent resection at our hospital between April 1, 2017 and March 31, 2021. We classified the patients into 2 groups: those who underwent tumor embolization and those who did not undergo tumor embolization; we retrospectively analyzed the changes in body temperature. In addition, based on the amount of contrast medium used, the patients were divided into a group using ≥100 mL and a group using <100 mL for examination.
Results: In the group that underwent tumor embolization, an increase in body temperature was observed in all patients; the prevalence of fever was significantly higher among those who underwent tumor embolization than among those who did not undergo embolization. The body temperature of the group using ≥100 mL of contrast medium was significantly higher than that of the group using <100 mL of contrast medium.
Conclusion: The body temperature rises significantly after tumor embolization; therefore, if fever is observed before excision, it is considered that the amount of contrast medium used or tumor embolization is a causal factor. In addition, this finding shows that the development of fever after tumor embolization may not necessarily be attributed to an infectious disease; this further reduces the burden on patients and medical staff.
