Surgery for giant meningiomas carries a high risk of bleeding and is time-consuming. This historical control study tests the hypothesis that the use of radio frequency thermocoagulation (RFT) during surgery improves outcome.
From November 2010 to October 2011, 20 giant vascularized meningiomas were surgically resected with intraoperative use of ultrasound-guided RFT prior to resection. The historical control group consisted of 25 patients in whom tumors were removed without RFT by the same surgical team. Blood loss during resection, changes in tumor consistency, time taken for the operation, and the extent of resection were compared between the two groups.
There was less blood lost during resection and the duration of the operation was shorter in RFT-assisted surgery than in the historical control group (P<0.05). Apart from the effect of devascularization, the tumor consistency became soft after RFT, which could also be beneficial.
Satisfactory devascularization and tumor softening were achieved after RFT without incremental complications. RFT-assisted surgery for giant vascularized supratentorial meningiomas is easier and safer than non-RFT surgery.
巨大脑膜瘤手术出血风险高且耗时。本历史对照研究旨在验证手术中使用射频热凝术（RFT）可改善手术结果这一假设。
2010年11月至2011年10月期间，对20例巨大血管化脑膜瘤在切除术前采用术中超声引导下的RFT进行手术切除。历史对照组由25例由同一手术团队在未使用RFT情况下切除肿瘤的患者组成。比较两组手术切除过程中的失血量、肿瘤质地变化、手术时间以及切除范围。
与历史对照组相比，RFT辅助手术切除过程中的失血量更少，手术时间更短（P<0.05）。除了去血管化作用外，RFT后肿瘤质地变软，这也可能有益。
RFT后实现了令人满意的去血管化和肿瘤软化，且未增加并发症。对于巨大血管化幕上脑膜瘤，RFT辅助手术比非RFT手术更简便、更安全。
