巨大脑膜瘤的术前栓塞

Preoperative Embolization of Gigantic Meningioma

目的探讨术前栓塞对巨大脑膜瘤手术切除的作用。方法14例经CT、MR诊断的直径在6～11cm的巨大脑膜瘤患者，术前在局麻下行DSA检查证实为富血管脑膜瘤，明确供血动脉后经微导管行供血动脉明胶海绵栓塞，栓塞3～7d均行手术切除。结果微导管均达到脑膜瘤供血动脉，注入适量的明胶海绵粉末后，9例完全栓塞，肿瘤和肿瘤染色完全消失；5例肿瘤染色大部分消失。14例栓塞后均顺利实施肿瘤手术切除，与既往未栓塞病例比较，行术前栓塞的病例术中出血明显减少，手术视野清晰，容易分块切除，手术时间缩短。14例均未出现手术并发症。结论术前栓塞巨大脑膜瘤使肿瘤切除更为容易，术中出血明显减少，手术时间缩短，能提高手术安全性，明显降低手术并发症和死亡率。

Objective To evaluate the clinical efficacy of preoperative embolization in treatment of patients with gigantic meningioma. Methods Fourteen cases of gigantic meningioma diameter from 6 to 11 cm were measured by CT and MRI scan. DSA manifested that they are vascularizd meningioma and showed the mainly feeding arteries. We used getation sponge to superselectively embilized the feeding arteries. All tumors were performed surgical excision 3-7 days after the embolization. Results DSA showed the blood supplies in the tumors in 9 cases were completely blocked, and that in 5 cases were dramatically eliminated. All patients were operated 3-7 days after the embolization. During the operations the bleeding were dramatically decreased and the operation time was shortened compared with those in unemDolized cases. It helps us remove the tumors easy and quickly from the attachments. No complication occurred during and after the operations. Conclusion Preoperative embolization of gigantic meningioma is a useful and relatively safe method in helping surgicaly and completely excised of tumor with significant reduction of blood loss and operation time.
