Background: Preoperative embolization of highly vascular intracranial meningiomas facilitates their surgical resection. The timing of preoperative embolization stays debatable. In our study, the effect of preoperative embolization of intracranial meningioma on surgical outcomes is assessed.
Aim is to evaluate the impact of preoperative embolization of intracranial meningiomas on surgical outcome.
Patients and methods: a planned report was done to assess the effect of preoperative endovascular embolization on surgical outcome of intracranial meningiomas worked from May 2018 to May 2020. In this study, twenty patients with intracranial meningioma went through preoperative embolization followed by surgical resection following 1-5 days. These patients included 12 Female and 8 Males and age went from 35years to 68years with mean age 51.5years. Most frequent locations are Sphenoid wing meningioma and parasagittal meningioma.
Results: Total and near total disappearance of tumor blush achieved in eighteen patients, while partial obliteration of tumor blush was achieved in two patients. No permanent morbidity or mortality in all patients. Fifteen patients were operated in the 2nd post-embolization day. Significant reduction of operative time that ranged from 3h to 6h with a mean of 4.5 hours and the intraoperative blood loss was reduced in eighteen patients and there was no need for transfusion in tow patients with mean amount of blood transfusion of 300 cc.
Conclusion: Preoperative embolization was shown to be safe and effective technique as a preoperative procedure that facilitated meningioma surgical resection with marked reduction of blood loss
