目的　探讨脑膜瘤术前超选择性颈外动脉栓塞术在临床手术的应用价值及脑膜瘤供血情况。方法　 2 3例经CT或MR诊断的脑膜瘤 ,术前均先行颈外动脉造影并超选择性栓塞术。结果　所有术前作颈外动脉栓塞的脑膜瘤 ,肿瘤体积缩小 ,手术切除容易 ,术中出血减少 ,手术时间缩短。结论　对脑膜瘤术前行颈外动脉造影并超选择性栓塞是临床安全及行之有效的方法 ,值得推广应用 Objective To investigate the value of preoperative selective external carotid artery embolization in meningeal tumor and the blood supply of meningioma. Methods Twenty-three cases of meningioma diagnosed by CT or MR were treated with external carotid artery angiography and superselective embolization before operation. Results All preoperative external carotid artery embolization of meningioma, tumor size reduced, surgical resection easy, less bleeding, surgery time shortened. Conclusion Preoperative carotid artery angiography and superselective embolization of meningioma is a safe and effective method, which is worth popularizing and applying
