目的 :分析总结术前PVA栓塞辅助治疗高血供脑膜瘤的方法、病例选择及开颅术中、术后肿瘤的改变。方法 :回顾分析 13例术前用PVA栓塞的高血供脑膜瘤病例并与未作栓塞的病例比较。结果 :13例术前用PVA栓塞的高血运脑膜瘤患者 ,手术过程发现肿瘤中心坏死 ,瘤体缩小 ,分离较容易 ,出血明显减少 ,肿瘤切除难度减少 ,安全性增加。结论 :术前PVA栓塞辅助治疗高血供脑膜瘤有利于减少术中出血 ,增加手术安全性 OBJECTIVE: To analyze and summarize the methods of adjuvant treatment of high blood supply of meningiomas with PVA embolization, the choice of cases and the changes of postoperative tumor during craniotomy. Methods: A retrospective analysis of 13 cases of preoperative embolization with PVA meningioma cases and non-embolized cases were compared. Results: Thirteen patients with high blood supply meningioma preoperatively with PVA embolization showed tumor center necrosis, tumor shrinkage and separation more easily. The hemorrhage was significantly reduced, the difficulty of tumor resection was reduced and the safety was increased. Conclusion: Preoperative PVA embolization adjuvant treatment of high blood supply of meningioma is conducive to reduce intraoperative bleeding and increase the safety of surgery
