[Clinical application of presurgical embolization of meningiomas].
OBJECTIVE
To evaluate the clinical efficacy and safety of presurgical embolization of meningiomas.


METHODS
Matched analysis of samples of embolized and nonembolized groups of meningiomas were observed for variables of clinical efficacy in estimated blood loss, number of transfusions and length of post-operative recovery.


RESULTS
All mean value of variables of embolized group, were lower than that of non-embolized (estimated blood loss, 1402.97 +/- 1171.60 ml versus 1852.94 +/- 993.40 ml; number of transfusions, 1325.53 +/- 1040.15 ml versus 1747.06 +/- 959.24 ml; length of post surgical recovery, 30.18 +/- 20.24 days versus 33.29 +/- 27.54 days); however, only the estimated blood loss and number of transfusions-variables were significant. There were no major complications caused by the embolization procedure.


CONCLUSIONS
Endovascular devascularization of meningiomas is beneficial for meningiomas because it diminishes the necessity of intra operative transfusion and decreases blood loss. Otherwise the embolization procedure is safe.
