Description
The aim of this study was to determine the clinical safety and efficacy of preoperative embolization of meningiomas with low-concentration n-butyl cyanoacrylate (NBCA). Nineteen cases of hypervascular intracranial meningiomas were treated by preoperative embolization with 14% NBCA, using a wedged superselective catheterization of feeding arteries and reflux-hold-reinjection technique. Clinical data of the patients and radiological and intra-surgical findings were reviewed. All tumors were successfully devascularized without any neurological complications. Marked reduction of tumor staining with extensive NBCA penetration was achieved in 13 cases. Perioperative blood transfusion was only required in two cases. These results indicate that preoperative embolization of meningiomas with low-concentration NBCA is both safe and effective.
