Purpose : To evaluate the efficacy and safety of preoperative embolization of intrancranial meningioma.Materials and Methods : We retrospectively reviewed intrancranial meningioma patients (n=37) who underwent preoperative embolization. They were categorized into two groups, skull base lesions (n=22) and non-skull base lesions (n=15), according to tumor location. In addition, embolization results were classified by comparison between pre-and post-embolization angiography as complete (residual tumor staining<10 or 30 %) or incomplete(residual tumor staining$\geq$10 or 30%). In each group, estimated blood loss (EBL) was estimated by amount of intra operative transfusion with pre- and post-operative hemoglobin level. Tumor resectability was evaluated by follow-up computed tomography. New symptoms occurring within 24 hours of embolization were considered to be those associated with embolization ; symptoms improved by conservative treatment were regarded as mild, while those resulting in new deficits were considered severe. Results : In the group with skull base lesions (n=22), complete embolization with the criteria of residual tumor staining of less than 30% was performed in 14 patients(EBL=1770ml ; complete surgical removal in nine patients and incomplete removal four). Incomplete embolization was performed in eight patients (EBL=3210ml; complete and incomplete removal each in four patients). In the group with non-skull base lesions, complete embolization with the criteria of residual tumor staining of less than 10% was performed in five patients (EBL=970ml) and incomplete embolization in ten (EBL=2260ml). Complete tumor removal was possible in this group regardless of the completeness of preoperative tumor embolization. In a case of intraventricular meningioma (3%), intratumoral hemorrage occurred on the day following embolization. Other mild post-embolization complications occurred in three cases (8%). Conclusion : Preoperative embolization can be an effective and safe procedure for meningioma and may reduce intraoperative blood loss. Its effectiveness may depend on tumor location and the degree of embolization, though the procedure seems to be helpful for lseions at the skull base.
