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.
Conclusion:
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.
