    Description / Table of Contents: Résumé On admet généralement que le sinus sagittal supérieur naît dans le foramen caecum. Mais 58% des cadavres examinés présentaient une atrésie de 1à 3 cm de l’extrémité la plus rostrale du sinus. Dans ces cas, les veines des pôles frontaux du cerveau se dirigeaient vers le milieu et le bas pour se joindre sur la ligne médiane, formant le lument du sinus. En cas d’atrésie plus étendue, les veines cérébrales antéro-supérieures et les veines des pôles inféro-médians sont médianes et se dirigent vers l’arrière pour former le sinus. En d’autres termes, plus l’atrésie est étendue, plus les modifications des veines sont importantes sur les parties supérieures et médio-frontales du cerveau.
    Abstract: Zusammenfassung Bei einer Atresie des rostralen Sinus-Abschnitts die mehr oder weniger ausgeprägt sein kann, kommt es zu einer bestimmten Veränderung des venösen Abflusses im Bereich der Frontallappen.
    Notes: Summary It has been accepted generally that the supperior sagittal sinus takes origin at the foramen caecum. While this obtains in a few, 58 per cent of the cadaver specimens examined have a one-to-three centimeter atresia of the most rostral end of the sinus. In these the veins of the frontal poles of the brain were directed medially and caudally to join in the midline, thus establishing the lumen of the sinus. In instances of more extensive atresia, the anterior superior cerebral veins, as well as those from the infero-mesial poles, all course medially and caudally to form the sinus. In other words, the longer the atretic segment, the more striking the change in venous patterns of the superior and mesial frontal lobes of the brain.

    Notes: The cerebral and dural venous systems are derived from separate layers of the vascular plexus that cover the brain in early embryonic life. The cerebral veins arise from the inner layer of the plexus which invests the neural tube and join the dural systems in the superior midline concomitant with the development of the sinuses. The dural veins, the lateral lacunae and the dural sinuses arise from the outer embryonic plexus. In the fully developed human these two systems are separate except for an occasional communication between a lateral lacuna and a superior cerebral vein just before the vein joins the superior sagittal sinus. The lateral lacunae are a distinct anatomical entity and their venous meshwork is to be regarded as a part of the dural venous system.
