What is hypoplastic transverse sinus?

Hypoplasia was defined as a transverse sinus diameter less than 50[percnt] of the cross-sectional diameter of the lumen of the distal superior sagittal sinus.

What does hypoplastic right transverse sinus mean?

Hypoplasia was defined as a transverse sinus diameter less than 50% of the cross-sectional diameter of the lumen of the distal superior sagittal sinus. Univariate analysis was performed to evaluate the association between transverse sinus hypoplasia (TSh) and thrombosis.

Is hypoplastic transverse sinus normal?

Anatomical asymmetry of transverse sinuses (TS) is a common finding and was considered a normal variant, as unilateral hypoplasia or aplasia is observed in 20% to 39% of cases.

What does the transverse sinus do?

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.

What is hypoplastic symptom?

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 causes narrowing of the transverse sinus?

From my experience with hundreds of patients, one of the most common cause of venous sinus stenosis is enlargement of arachnoid granulations. The arachnoid granulations are valves that normally occur in the wall of the venous sinuses and facilitate from of CSF from the brain to the bloodstream.

Which transverse sinus is dominant?

superior sagittal sinus
Each transverse sinus originates at the level of the internal occipital protuberance. Most commonly, the right transverse sinus arises from the superior sagittal sinus and it is usually larger than the left one. The left transverse sinus is usually continuous with the straight sinus.

What does hypoplastic mean?

Is transverse sinus thrombosis a stroke?

Background. Cerebral venous sinus thrombosis (CVST) is a type of stroke in which the venous channels of the brain become thrombosed, resulting in cerebral infarction in the areas corresponding to the thrombosis. CVST is uncommon.

Is hypoplasia A?

How do you treat hypoplasia?

In the case of sensitivity, cavities, or tooth structure showing wear, treatment options include:

Resin-bonded sealant. This can improve tooth sensitivity.
Resin-based composite fillings.
Dental amalgam fillings.
Gold fillings.
Crowns.
Enamel microabrasion.
Professional dental whitening.

How is transverse sinus stenosis treated?

While the role of transverse sinus stenosis in IIH pathogenesis remains controversial, modeling studies suggest that stent placement within a transverse sinus stenosis with a significant pressure gradient should decrease cerebral venous pressure, improve CSF resorption in the venous system, and thereby reduce …

What does transverse sinuses mean?

What is a left transverse sinus?

Description. The transverse sinuses (also called left and right lateral sinuses of the dura mater) are two cavities 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, and drain from the confluence of sinuses…

What is transverse venous sinus?

Transverse Sinus. The transverse sinuses are paired dural venous sinuses that drain the confluence of sinuses (a meeting place of the superior sagittal , straight, occipital, and transverse sinuses), where they begin, and run along the occipital attachment of the tentorium cerebelli to terminate in the sigmoid sinus.

What is left sigmoid sinus?

The sigmoid sinus is actually a pair of two sinuses (right and left) that enable veins to spread from the middle of the head downwards. This dual structure is considered an extension of the transverse sinus, which lies in the hind portion of the brain.
