Full Answer

What is sagittal sinus thrombosis?

Sagittal sinus thrombosis is the most serious disorder of the intracranial venous pathways. This condition frequently leads to headache (80%), swelling of the optic nerve (papilledema, 50%), motor or sensory deficits (35%), seizures (29%), hemorrhage (50%), and death (5%–10%).

Suppurative thrombophlebitis of the superior sagittal sinus, however, is uncommon and occurs significantly less frequently than does septic thrombosis of the cavernous or transverse sinuses.

What is a sagittal sinus thrombosis?

Background Superior sagittal sinus thrombosis is an uncommon cerebrovascular accident that is frequently associated with diseases that may contribute to the development of thrombosis through hypercoagulability, stasis of the local blood stream, and abnormalities of the vessel wall.

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. Overall, about 3 out of 300,000 children and teens up to age 18 will have a stroke.

What does cavernous sinus thrombosis mean?

Cavernous sinus thrombosis is a blood clot in the cavernous sinuses. It can be life-threatening. The cavernous sinuses are hollow spaces located under the brain, behind each eye socket. A major blood vessel called the jugular vein carries blood through the cavernous sinuses away from the brain.

What is lateral sinus thrombosis?

Septic lateral sinus thrombosis (LST) is an intracranial complication of acute/chronic suppurative otitis media, which is between 2% to 20% of the intracranial complications. Septic LST is the formation of thrombi in the sigmoid/transverse sinus and it can reach the jugular bulb and the internal jugular vein.

Where is the sagittal sinus?

The superior sagittal sinus (SSS), which is the longest dural sinus, lies along the superior edge of the falx cerebri, which is attached to the crista galli at the interhemispheric space just underneath the cranial vault.

What causes sinus thrombosis?

Cavernous sinus thrombosis is usually caused by a bacterial infection that spreads from another area of the face or skull. Many cases are the result of an infection of staphylococcal (staph) bacteria, which can cause: sinusitis – an infection of the small cavities behind the cheekbones and forehead.

What does the superior sagittal sinus do?

The superior sagittal sinus drains blood from cortical veins of the cerebral hemispheres, veins of the falx cerebri and meninges, diploic veins of the skull and emissary veins from the scalp. It empties into the confluence of sinuses in the occipital region.

Is cavernous sinus thrombosis unilateral or bilateral?

Cavernous sinus thrombosis has a distinctive clinical picture that includes, in classic acute cases, chemosis, proptosis, and painful ophthalmoplegia, initially unilateral but frequently becoming bilateral.

Where is the cavernous sinus located?

Is a venous 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. Overall, about 3 out of 300,000 children and teens up to age 18 will have a stroke.

What is sigmoid sinus thrombosis?

Lateral sinus thrombosis, also known as sigmoid sinus thrombosis, forms when infection from the adjacent mastoid contacts and penetrates the venous wall and forms a thrombus. Embolization of the thrombus can cause distal disease.

What kind of stroke is a cerebral venous sinus thrombosis?

Cerebral venous sinus thrombosis (CVST) is a blood clot in one of your brain's larger veins. This rare issue makes up 1% of types of stroke. When a blood clot blocks a major vein in your brain, your blood flows the wrong way. This increases the pressure in your brain and causes it to swell.

Is CVST an ischemic stroke?

CVST occurs when a clot forms in the cerebral venous system or dural sinuses, which may lead to venous congestion, cerebral edema, and ischemic and/or hemorrhagic stroke. Overall, 75% of CVST occur in women (Ferro et al., 2004).

What kind of stroke is a cerebral venous sinus thrombosis?

Cerebral venous sinus thrombosis (CVST) is a blood clot in one of your brain's larger veins. This rare issue makes up 1% of types of stroke. When a blood clot blocks a major vein in your brain, your blood flows the wrong way. This increases the pressure in your brain and causes it to swell.

Is cerebral venous sinus thrombosis serious?

For every 100,000 people, there are only about 0.22 to 1.57 cases of cerebral venous thrombosis each year. But CVST is a dangerous and potentially lethal disorder. It can cause a range of symptoms, from headache to impaired vision to problems speaking to, in severe cases, coma.

What does transverse sinus drain into?

The transverse sinuses are formed by the tentorium cerebelli and drain into the right and left sigmoid sinuses.

What is sagittal sinus thrombosis?

Sagittal sinus thrombosis is the most serious disorder of the intracranial venous pathways. This condition frequently leads to headache (80%), swelling of the optic nerve (papilledema, 50%), motor or sensory deficits (35%), seizures (29%), hemorrhage (50%), and death (5%–10%). Contrast enhanced CT scanning allows superior sagittal sinus thrombosis to be diagnosed by showing the “empty delta” sign. Now, MR is the preferred test, showing increased signal intensity on T1, T2, and proton density weighted images. The clot can be directly visualized using such routine MR techniques, and MRV can easily demonstrate the absence of venous blood flow caused by the thrombus. CT venography (CTV) may be preferable in some situations. Although catheter angiography will demonstrate the problem during the venous phase of contrast washout, CTA, CTV, MRA and MRV have greatly reduced the need for conventional cerebral angiography for the diagnosis of sagittal sinus thrombosis and other sinovenous occlusive diseases.

What is the most common organism associated with septic superior sagittal sinus thrombophlebit

Prior to the availability of antibiotic therapy, most cases of septic superior sagittal sinus thrombophlebitis were due to S. pneumoniae or H. influenzae. S. pneumoniae remains the most common organism associated with this condition, with a minority of cases due to S. aureus, β-hemolytic, microaerophilic, or anaerobic streptococci, ...

When does central venous thrombosis occur?

Central venous thrombosis usually occurs in the first three postpartum weeks and commonly presents with headache, focal or generalized seizures, stupor or coma, transient focal deficits, and/or signs of increased intracranial pressure. Rare thromboses include superior sagittal sinus thrombosis, with paraplegia and sensory deficits of the leg and bladder dysfunction, and rolandic vein thrombosis, with sensory and motor deficits of the leg, hip, and shoulder, sparing the face and arm. Mortality in sagittal sinus thrombosis approaches 40% but may be reduced to 20% with intensive care and, in some cases, anticoagulants. Recovery of survivors is usually complete.

What is the Dense Triangle of Thrombus?

Is LS thrombosis asymptomatic?

Like SSS thrombosis, LS thrombosis has a variable presentation. Although it can be asymptomatic, isola ted LS thrombosis usually manifests as raised intracranial pressure; hence the term otitic hydrocephalus coined by Symonds 10 to describe the effects of LS thrombosis secondary to an active or latent ear infection.

Is sagittal sinus thrombosis more common than septic thrombosis?

The ICD code I676 is used to code Cerebral venous sinus thrombosis

Cerebral venous sinus thrombosis (CVST) is the presence of acute thrombosis (a blood clot) in the dural venous sinuses, which drain blood from the brain. Symptoms may include headache, abnormal vision, any of the symptoms of stroke such as weakness of the face and limbs on one side of the body, and seizures.
