Ligation and resection of the superior longitudinal sinus is a formidable task which must be undertaken in cases of certain tears through the sinus to control hemorrhage or when a meningioma involves the sinus. Meningiomas frequently have their origin of growth from the wall of the sinus, and may invade it often to the extent of completely occluding the lumen of the vessel. In order to effect a permanent cure, the involved portion of the sinus must be removed.
Resection of a sinus previously occluded by a tumor—in effect already resected—would not seem to be dangerous, because the gradual closure of the vessel has permitted sufficient time for an adequate collateral circulation to be slowly established. However, the resection or ligation of a superior longitudinal sinus not already closed is quite another matter. Ligation of a vein invariably leads to temporary venous stagnation and edema in the tissues drained by
