Clinical analysis of preoperative super-selective embolization in patients with large meningiomas

Abstract

Nineteen cases of large meningiomas underwent microcatheter preoperative super-selective embolization before surgical resection. A total of 30 blood supply arteries underwent preoperative embolization, including total embolization (2 cases), most part of embolization (8 cases), partial (6 cases) and a small amount of embolization (3 cases). Tumor resection in patients with complete embolism had low blood loss of (215.84 ± 62.42) ml, no blood transfusion and less operation time (2.15 ± 1.01) h, and the degree of surgical removal achieved Simpson grade Ⅰ, with statistically difference from other groups (P < 0.05, for all). Super?selective preoperative embolization can significantly reduce blood supply to the tumor, reduce intraoperative blood loss and decrease the difficulty of surgical resection, so it can be used as an important adjuvant treatment for meningioma surgery.
