Superior Anastomotic Vein
The superior anastomotic vein, also known as the vein of Trolard, is a superficial cerebral vein grouped with the superior cerebral veins. The vein was eponymously named after the 18th century anatomist Jean Baptiste Paulin Trolard. The vein anastomoses with the middle cerebral vein The middle cerebral veins are the superficial middle cerebral vein and the deep middle cerebral vein. * The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere, running along the lateral sul ... and the superior sagittal sinus.

Superficial Cerebral Veins
The superficial cerebral veins are a group of cerebral veins in the head. This group includes the superior cerebral veins, the superficial middle cerebral vein, the inferior cerebral veins, the inferior anastomotic vein and the superior anastomotic vein The superior anastomotic vein, also known as the vein of Trolard, is a superficial cerebral vein grouped with the superior cerebral veins.

Superior Cerebral Vein
The superior cerebral veins, numbering eight to twelve, drain the superior, lateral, and medial surfaces of the hemispheres. They are predominantly found in the sulci between the gyri, but can also be found running across the gyri. Individually they drain into the superior sagittal sinus The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispher .... The anterior veins run at near right angles to the sinus while the posterior and larger veins are directed at oblique angles, opening into the sinus in a direction opposed to the current (anterior to posterior) of the blood contained within it.

Jean Baptiste Paulin Trolard
Jean Baptiste Paulin Trolard (27 November 1842 in Sedan, Ardennes – 13 April 1910) was an anatomist known for his work on the anastomotic veins of the cerebral circulation. The "vein of Trolard" (the superior anastomotic vein) was named after him. He studied medicine at the Algiers Preparatory College of Medicine, afterwards working as a municipal physician in Saint Eugène, a suburb of Algiers. In 1861, he began work as an anatomy prosector at the college. From 1869 to 1910, he was a professor of anatomy at the Mustapha Pacha hospital Algiers.

Anastamosis
An anastomosis (, plural anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus's heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Gr ana- "up, on, upon", stoma "mouth", ...

Middle Cerebral Vein
The middle cerebral veins are the superficial middle cerebral vein and the deep middle cerebral vein. * The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere, running along the lateral sulcus, and ends either in the cavernous sinus or the sphenoparietal sinus. * The deep middle cerebral vein (deep Sylvian vein) receives tributaries from the insula and neighboring gyri, and runs in the lower part of the lateral sulcus. Connections The superficial middle cerebral vein is connected: # with the superior sagittal sinus by the superior anastomotic vein (vein of Trolard) where the latter opens into one of the superior cerebral veins; # with the transverse sinus by the inferior anastomotic vein (vein of Labbé) which courses over the temporal lobe The temporal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The temporal lobe is located beneath the lateral fissure on both c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superior Sagittal Sinus
The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses. Cerebrospinal fluid drains through arachnoid granulations into the superior sagittal sinus and is returned to venous circulation. Structure Commencing at the foramen cecum, through which it receives emissary veins from the nasal cavity, it runs from anterior to posterior, grooving the inner surface of the frontal, the adjacent margins of the two parietal lobes, and the superior division of the cruciate eminence of the occipital lobe. Near the internal occipital protuberance, it drains into the confluence of sinuses and deviates to either side (usually the right). At this point it is continued as the corresponding transverse sinus. The superior sagittal sinus is usually divided into three parts: anterior ...
