Where is the vein of Trolard?

Where is the vein of Trolard?

The superior anastomotic vein (or vein of Trolard) is the largest superficial vein on the lateral surface of the parietal or frontal lobe that connects the superior sagittal sinus and the superficial middle cerebral vein (of Sylvius). It usually runs in the post-central sulcus draining the adjacent cortex.

What does the vein of Labbe do?

The vein of Labbe, or inferior anastomotic vein, is part of the superficial central venous system and drains the temporal lobe and tissue adjacent to the Sylvian fissure. It connects the superficial middle cerebral vein draining into the transverse sinus.

What is the straight sinus?

The straight sinus, also known as tentorial sinus or the sinus rectus, is an area within the skull beneath the brain. It receives blood from the inferior sagittal sinus and the great cerebral vein, and drains into the confluence of sinuses. Straight sinus. Dural veins (Straight sinus labeled as ‘SIN.

What is the Torcular Herophili?

The torcular Herophili (confluence of sinuses) is a highly variable structure that constitutes a vital part of the network of dural venous sinuses. The torcular Herophili is defined historically as the intersection of the superior sagittal sinus, the straight sinus, the occipital sinus, and the two transverse sinuses.

Which sinus does the straight sinus drain?

transverse sinus
The SS most commonly empties into the transverse sinus but may also drain directly into the confluence of sinuses or the torcula. There is a predominance of drainage of the straight sinus into the left transverse sinus as opposed to the right (Rhoton, 2002).

Which vein drains into straight sinus?

the great cerebral vein
The straight sinus, also known as tentorial sinus or the sinus rectus, is an area within the skull beneath the brain. It receives blood from the inferior sagittal sinus and the great cerebral vein, and drains into the confluence of sinuses.

How is a anastomosis performed?

In most cases, anastomosis can be performed using laparoscopy. Laparoscopy means that the surgery is done through a small incision using a small instrument called a laparoscope. A laparoscope is a long, thin tube with a camera and light at the end of it. It helps doctors see inside your body while they perform surgery.

What is torcular?

Definition of torcular : the point at which the four great cranial venous sinuses meet.

What is a torcula?

The confluence of sinuses, torcular herophili, or torcula is the connecting point of the superior sagittal sinus, straight sinus, and occipital sinus. It is found deep to the occipital protuberance of the skull. Blood arriving at this point then proceeds to drain into the left and right transverse sinuses.

What does the straight sinus become?

The straight sinus ends at the internal occipital protuberance, a bony landmark on the cranium, and empties into the transverse sinus contributing to the formation of the confluence of sinuses.

What is a vascular sinus?

Athos Patsalides, Interventional Neuroradiologist, New York, NY| Conditions & Treatments|Venous Sinus Stenosis. Venous Sinuses (or Dural Venous Sinuses) are the large veins of the brain. Their function is to facilitate blood flow from the brain to the neck and the heart.

What does the straight sinus do?

As it courses toward the internal occipital protuberance, the straight sinus may receive drainage from the vermian veins and the superior cerebellar hemispheric veins via the vein of Galen. The SS most commonly empties into the transverse sinus but may also drain directly into the confluence of sinuses or the torcula.

How can I naturally increase blood flow to my brain?

Fast walking, running, cycling, swimming, ball playing, weight lifting and yoga all help improve cranial blood flow, says Ignarro: “Physical activity stimulates the production of NO in all arteries, including those in the brain.” In one study, women over 60 that walked for 30 to 50 minutes three or four times a week …
