=====Venous infarction=====
Every venous structure should be preserved even if they seem to lack significant function. This will help prevent complications associated with delayed lobar parenchymal hemorrhage that can be attributed to [[venous infarction]].

The incidence of venous infarction after surgical resection of meningioma is low, but its occurrence can necessitate additional surgical procedures and long hospital stay. 

Sacrifice of the [[straight sinus]] is associated with an unpredictable risk of venous infarction.

Venous infarction was the most frequent complication in a study of parasagittal meningioma, developed in 12 (9.2%) patients. The outcome after removal of parasagittal meningiomas was related to the patient condition prior to surgery (p = 0.000), postoperative complications (p = 0.001), tumor site (p = 0.05) and invasion of SSS by the tumor (p = 0.04). Venous infarction was the most frequent postoperative complication. It is possible to reach total meningioma's removal by ablation of SSS and replacing it by peripherical venous
