  • Title: Obstruction of the superior sagittal sinus caused by parasagittal meningiomas: the role of collateral venous pathways.
    Author: Oka K, Go Y, Kimura H, Tomonaga M.
    Journal: J Neurosurg; 1994 Oct; 81(4):520-4. PubMed ID: 7931584.
    Abstract:
    The authors present studies of eight patients who had obstruction of the superior sagittal sinus caused by parasagittal meningioma. The results indicate that meningeal veins and end-to-end anastomoses of the superficial veins of the cerebrum play important roles as collateral venous pathways. This assessment suggests that, in patients with obstruction of the superior sagittal sinus, venous phase angiography should be carefully interpreted before surgery is attempted for parasagittal meningiomas.
