The value of pre-operative embolisation of meningioma estimated subjectively and objectively

In a personal series a comparison has been made of the subjective and objective assessments of benefit between a group of patients in whom preoperative embolisation for meningioma was performed and a group, referred during the same timescale, in whom embolisation was either not possible or not appropriate. Preoperative difficulty with bleeding was experienced in 25% of the embolisation group and in 62% of the non-embolised group. Blood replacement overall was less in the embolised patients. Surgical complications occurred in 21% of those embolised but in 54% of those in whom embolisation had not been performed. At follow-up the outcome was rated as good in 79% in the embolisation group as opposed to 58% in the non-embolised group. Preoperative embolisation was therefore beneficial.
