Abstract: Objective To explore the applicable conditions and clinical effects of preoperative external carotid artery ligation (LCE) in lateral sphenoid ridge meningiomas (SRM). Methods Thirty-two patients with SRM were divided into LCE group (n = 14) and non?LCE group (n = 18). Differences were observed between the two groups. Results The average variables of LCE group were less than non-LCE group. In LCE group and non-LCE group, the blood loss volume was (471.00 ± 182.00) ml and (994.00 ± 278.00) ml respectively, total removal rate was 100.00% and 72.22% respectively, and the surgical time was (5.60 ± 1.40) h and (8.10 ± 1.70) h respectively. The postoperative complication rate of LCE group (1/14, 7.14%) was significantly less than non-LCE group (7/18, 38.89%; P = 0.047). Conclusion For large and huge tumors of the lateral SRM, preoperative LCE can significantly reduce intraoperative bleeding and surgical time, simultaneously improve the operation security and the total removal rate.

摘要： 探讨外侧型蝶骨嵴脑膜瘤术前结扎颈外动脉的适用条件和临床效果。32 例大型、巨大型蝶骨嵴外侧型脑膜瘤患者分为颈外动脉结扎组和未结扎组，术后统计显示，两组患者术中失血量分别为（471.00 ± 182.00）ml和（994.00 ± 278.00）ml、肿瘤全切除率100.00%（14/14）和72.22%（13/18）、手术时间分别为（5.60 ± 1.40）h 和（8.10 ± 1.70）h、发生术后并发症病例分别为1 例（7.41%）和7 例（38.89%）；各项变量比较颈外动脉结扎组均优于未结扎组，组间差异具有统计学意义（P < 0.05 或P < 0.01）。提示：大型、巨大型蝶骨嵴外侧型脑膜瘤患者术前结扎颈外动脉可显著减少术中出血、缩短手术时间、提高手术安全性和肿瘤全切除率。
