[Occlusion of the superior sagittal sinus caused by meningioma, intracranial volume-pressure relations and brain edema].
Fifty-one cases of parasagittal meningiomas were analysed. In 37 cases the tumour was situated in the middle and posterior part of the falx. In 17 cases occlusion of the superior sagittal sinus was diagnosed and confirmed by angiography. No correlation was found between the extent of brain oedema and sinus occlusion and tumour size. However, extensive oedema was present in tumours of high malignancy. Occlusion of the sagittal sinus caused no increase of intracranial pressure or venous stasis. This suggests that sinus occlusion caused by meningioma is completely compensated and has no effect on the preoperative and postoperative course.
