Objective: To investigate the effect of preoperative embolization combined with Kawase approach in the treatment of petroclival meningioma.
Methods: Retrospective analysis of 15 cases of preoperative embolization combined with Kawase approach surgical treatment of petroclival meningioma, and 15 cases of patients without preoperative embolization were treated as controls. The surgical difficulty, intraoperative blood loss and operation time of two groups were tested.
Result: The average blood loss of the preoperative embolization group was (315.52 ± 58.71 ml), the average blood transfusion was (185.35 ± 46.15 ml), the average operation time was (2.52 ± 0.59 h). The mean blood loss was (1136.25 ± 8.26 ml), and the average blood transfusion was (488.63 ± 62.32 ml), the average operation time was (5.15 ± 1.26 h) in the non-embolization group. The differences between the two groups were statistically significant (P<0.05). The degree of tumor resection in the preoperative embolization group was significantly higher than that in the non-embolization group.
Conclusion: Preoperative embolization can significantly reduce intraoperative blood loss, operation time, and decrease the difficulty of Kawase approach surgery.
