“…According to previous studies CSF pressure is slightly higher than sagittal sinus pressure in the normal state (Bering and Salibi 1959, Bedford 1934, Guthrie et al 1970, Shulman et al 1964. This pressure gradient between the CSF and dural sinuses is considered to be the driving force responsible for outflow of CSF from the intracranial subarachnoid space to the dural venous sinuses (Davson et al 1970).…”

“…Surgical occlusion is more focal and theoretically better tolerated than spontaneous thrombosis, which often involves more than one vein thus decreasing the chance for development of collaterals (Auque and Huot,1996). Animal studies did not show venous infarctions after ligation of the vein of Galen (Bedford,1934). Flow changes occur after occlusion as the ICVs drain in a retrograde fashion into the cortical veins, whereas the BVR drains into the temporal veins, the sphenoparietal sinus (Caron et al,1977) and subsequently into the basilar and petrosal sinuses through the cavernous sinus.…”

A thorough understanding of the anatomy of the pineal region, particularly venous drainage, is critical for gaining open surgical access to the pineal gland. The adverse sequelae after intraoperative venous occlusion are assumed to be catastrophic but have been scarcely reported. We report a case of pineocytoma in which the vein of Galen was ligated without postoperative adverse sequelae. Pineal region anatomy with emphasis on deep veins was reviewed in large anatomical studies. There are tremendous anatomical variations in the vein of Galen and its tributaries. Several confounding factors can be encountered during surgery and may lead to accidental sacrifice of the vein of Galen. Survival after focal occlusion of a major deep vein depends on the development of collateral circulation as shown in our case report. Venous drainage remains the cornerstone in the surgical planning of the pineal region. Anatomical variations and venous collaterals undoubtedly contributed to the mixed reports of adverse sequelae after venous sacrifice. Vein of Galen ligation may be survivable but consequences cannot be predicted without a thorough pre-ligation assessment of regional venous collateral drainage. Thorough understanding of the venous anatomy, meticulous planning of the surgical approach and avoidance of the occlusion of the vein of Galen and its major tributaries are key factors to successful pineal region surgery.

In the course of nasal sinus and middle ear infections, supervening signs of focal cerebral involvement are usually indicative of brain abscess.53, 25,93,5 There are, however, certain instances when brain abscess is strongly suspected because of signs of focal cerebral involvement but is not found on surgical exploration or demonstrated by contrast roentgenography, and, the clinical course reverses toward recovery.Adson! believed that, in this type of case, the infection extended into the brain but resolved without suppuration. He called the condition pseudo-brain abscess. Others have referred to it as acute non-suppurative encephalitis, or local non-suppurative meningitis.": 87Our interest in this problem was aroused by three patients (Cases Nos. 3,4 and 5) who presented themselves within a single year. They were remarkably alike in that they developed, in the course of paranasal sinus infection, focal seizures, hemiparesis and signs of meningeal irritation. They were strongly suspected of having abscess but appropriate investigation ruled otherwise, and, they recovered without the necessity of intracranial exploration. We can only speculate on the cause of the neurological signs.
