Role of Preoperative Embolization in Management of Central Nervous System Tumours.

Preoperative embolization plays a significant role as an adjunct to surgical intervention in the cases of certain vascular tumours of the brain. While the procedure has resulted in facilitated resection of the tumour, and has reduced morbidity and mortality, its application remains debatable within the neurosurgical community, owing to rare, but major post-procedural complications. Herein, we have reviewed the literature to assess the safety and efficacy of preoperative angiographic embolization for brain tumours.
