Clinical Effectiveness of Preoperative Embolization on Surgical Outcomes of Meningioma

Abstract

Introduction: Meningioma is the most common primary intracranial tumor, extra-axial, and originates from arachnoid cap cells attached to the dura mater. Tumors that grow significantly larger and patients with symptoms, can undergo surgical therapy. Pre-operative embolization is an additional treatment option for meningioma patients. This embolization is aimed at devascularizing the lesion or reducing tumor blood flow through the elimination of one or more arteries that supply tumor nutrients.

Method: A article review is carried out based on issues, methodologies, similarities, and further research proposals. Of the 5 studies used as a whole, the methods used were descriptive analysis and retrospective data collection during the study period.

Discussion: Based on 5 studies showing that pre-operative embolization of meningiomas aims to reduce tumor vascularization. There were no significant differences in complications, recurrence-free survival, estimated blood loss, surgical time, blood transfusion volume between the embolization and non-embolization groups.

Conclusion: Pre-operative embolization did not produce significantly favorable results. Preoperative embolization is recommended in patients with comorbid conditions and a higher disease severity index.
