What is left transverse sinus hypoplastic?

Hypoplastic left transverse sinus is the most common anatomical variation in the present study. Hypoplastic left transverse sinus is more common in male compared to female. Other anatomical variations of dural venous sinuses are not significantly differ among both genders.

What does transverse sinus mean?

The transverse sinuses (left and right lateral sinuses), within the human head, are two areas beneath the brain which allow blood to drain from the back of the head. They run laterally in a groove along the interior surface of the occipital bone.

Is transverse sinus thrombosis a stroke?

CVST is a rare form of stroke. It affects about 5 people in 1 million each year. The risk for this kind of stroke in newborns is greatest during the first month.

What is the hypoplasia?

Hypoplasia refers to a lack of cells in an organ or tissue. It can cause a range of different symptoms depending on where in the body it occurs. Many conditions involve hypoplasia. A person with one of these conditions may experience difficulty with using a certain part of their body.

What is hypoplastic sigmoid sinus?

Hypoplasia or total aplasia of the sigmoid sinus is usually seen on the left side. In cases of total absence or hypoplasia of both the transverse sinus and sigmoid sinus, the superior petrosal sinus may pass directly through the mastoid foramen, and a large inferior petrosal sinus may be present.

Which sinus is between the transverse sinus and the jugular foramen?

Sigmoid Sinus
The Sigmoid Sinus It begins inferior to the temporal bone, posteromedial to the mastoid cells, and runs to the jugular foramen, extending through an S-shaped groove, where it meets the superior jugular bulb (Figs.

Which transverse sinus is dominant?

2 Au- topsy and cerebral angiographic studies have consistently shown that a dominant transverse sinus is common, most commonly on the left. 2– 4 Only 37\% to 50\% of patients studied have equally sized transverse sinuses.

What are venous sinuses in brain?

The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous channels found between the endosteal and meningeal layers of dura mater in the brain.

What do dural venous sinuses do?

Together the dural venous sinuses form the major drainage pathways from the brain, predominantly to the internal jugular veins. It is important to note that the draining territories of intracranial veins are different from those of arterial territories of the major cerebral arteries.
