[Preoperative embolization with microspheres of giant supratentorial meningiomas: 5-year experience].

Background: Preoperative embolization of hypervascular tumours such as meningiomas has proven to be a favorable factor for resection of the latter because it diminishes intraoperative bleeding and the need for blood transfusions.

Objectives: Evaluation of surgical outcomes of preoperative embolization with microspheres of giant supratentorial meningiomas.

Methods: We retrospectively analyzed patient records from 2007 to 2012 with the diagnosis of giant supratentorial meningiomas (> 5 cm) (n= 27) and obtained two samples: those with preoperative embolization (n= 14) and patients without any properative embolization (n= 13).
