摘要

目的蝶骨翼脑膜瘤(SWM)常因肿瘤压迫导致大脑浅中静脉(SMCV)闭塞或狭窄。本研究旨在分析SWM患者SMCV受压与瘤周脑水肿(PTBE)之间的相关性,并阐明手术保留SMCV在SWM手术中的重要性。方法这项回顾性研究纳入了2011年4月至2022年3月期间在我院接受SWM手术的31例患者。通过术前和术后磁共振成像或数字减影血管造影评估了患者的人口统计学特征、肿瘤特征、PTBE大小以及手术前后SMCV的通畅情况。结果 在31例患者中,24例(77.4%)表现为PTBE,严重程度不一:轻度(32.3%)、中度(25.8%)和重度(41.9%)。术前磁共振成像显示,14 名患者(45.2%)的 SMCV 通畅,17 名患者(54.8%)的 SMCV 受压。PTBE 严重程度与 SMCV 受压之间存在明显关联(p = 0.002)。术前 SMCV 受压的 16 位患者中有 4 位(25.0%)术后观察到 SMCV 再通。与未发生再通的患者相比,这些患者的肿瘤明显更小(p = 0.013),术前 PTBE 体积明显更大(p = 0.042)。一部分患者术后出现了 SMCV 再通,尤其是那些肿瘤较小、PTBE 较明显的患者。这些发现强调了在 SWM 手术中保留 SMCV 以改善术后预后的重要性。

Impact of superficial middle cerebral vein compression on peritumoral brain edema of the sphenoid wing meningioma

Objective

Sphenoid wing meningiomas (SWMs) often cause occlusion or stenosis of the superficial middle cerebral vein (SMCV) by tumor compression. This study aimed to analyze the correlation between SMCV compression and peritumoral brain edema (PTBE) in SWM patients and to clarify the importance of surgical preservation of the SMCV in SWM surgery.

Methods

This retrospective study included 31 patients who underwent surgery for SWM at our institution from April 2011 to March 2022. Patient demographics, tumor characteristics, PTBE size, and SMCV patency before and after surgery were evaluated using preoperative and postoperative MRI or digital subtraction angiography.

Results

Of the 31 patients, 24 (77.4 %) exhibited PTBE, with varying degrees of severity: mild (32.3 %), moderate (25.8 %), and severe (41.9 %). Preoperative MRI showed SMCV patency in 14 patients (45.2 %) and SMCV compression in 17 patients (54.8 %). There was a significant association between PTBE severity and SMCV compression (p = 0.002). Postoperatively, SMCV recanalization was observed in 4 out of 16 patients (25.0 %) with preoperative SMCV compression. These patients had significantly smaller tumors (p = 0.013) and larger preoperative PTBE volumes (p = 0.042) compared to those without recanalization.

Conclusions

Our study demonstrates a significant correlation between SMCV compression and severe PTBE in SWM patients. A subset of patients showed postoperative SMCV recanalization, particularly those with smaller tumors and more pronounced PTBE. These findings highlight the importance of SMCV preservation during SWM surgery to potentially improve postoperative outcomes.
