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.
