摘要： 共19 例大中型脑膜瘤患者经微导管超选择性术前栓塞治疗后再行肿瘤切除术，其中达完全栓塞者2 例、大部分栓塞8 例、部分栓塞6 例、少量栓塞3 例。完全栓塞患者术中出血量（215.84 ±62.42）ml、手术时间（2.15 ± 1.01）h、肿瘤切除程度均达SimpsonⅠ级，与其余各组差异有统计学意义（均P < 0.05）。大中型脑膜瘤采取超选择性术前栓塞治疗可减少术中脑膜瘤血供、降低术中出血量，有利于顺利完成手术。

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.
