What does 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 causes sinus venous thrombosis?

Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brain's venous sinuses. The clot keeps blood from draining out of the brain. As a result, pressure builds up in the blood vessels.

A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.

How to treat sigmoid sinus thrombophlebitis?

Since the introduction of antibiotics, conservative medical treatment has evolved as the mainstay in the management of sigmoid sinus thrombophlebitis. Initiation of broad-spectrum antibiotics is the most important first step. In the presence of clinical and radiologic indications of underlying middle ear and mastoid involvement, a mastoidectomy is warranted, taking care to decompress the bone overlying the sigmoid sinus. Management of the thrombosis within the sinus by surgical manipulation or anticoagulation is controversial. In general, there is resolution of the thrombosis, with complete recanalization of the sigmoid sinus, within 4 to 6 weeks. 77 Thus, a more conservative approach may minimize the risk of surgical manipulation of the sigmoid sinus and anticoagulation. 78–80

What causes a septic thrombus in the middle ear?

Although the exact mechanism is unknown, the likely cause is by direct extension and thrombosis or by cerebral infarction, leading to tissue congestion and obstruction, and secondarily propagating to thrombosis.

What is the superior sagittal sinus?

The superior sagittal sinus is the largest of the venous sinuses ( Fig. 39-6), and it receives blood from the frontal, parietal, and occipital superior cerebral veins and the diploic veins, which communicate with the meningeal veins. Infection can spread from the meninges to the superior sagittal sinus via the diploic veins, especially in cases with purulent exudate near the superior sagittal sinus. The cerebral veins and venous sinuses have no valves; therefore, blood within them can flow in either direction. The superior sagittal sinus drains into the transverse sinus. The transverse sinuses also receive venous drainage from small veins from both the middle ear and the mastoid cells. The transverse sinus becomes the sigmoid sinus before draining into the internal jugular vein. Septic transverse or sigmoid sinus thrombosis can be a complication of acute and chronic otitis media or mastoiditis. Infection spreads from the mastoid air cells to the transverse sinus via the emissary veins or by direct invasion.

What is intracranial thrombophlebitis?

Septic intracranial thrombophlebitis is a bacterial infection of the cortical veins and sinuses with resultant venous thrombosis. It is a complication of bacterial meningitis, subdural empyema, epidural abscess, or infection in the skin of the face, paranasal sinuses, middle ear, or mastoid.

Stroke and Cerebrovascular Center

Sigmoid sinus diverticulum is a rare vascular finding due to an opening in the bone at the area of the sigmoid sinus creating a pouch, or diverticulum. Sometimes, there may be associated stenosis. The diverticulum may present as pulsatile tinnitus.

Diagnosis

Sigmoid sinus diverticulum can be diagnosed either by CT, CTA, MRI or MRV. Cerebral angiography provides definitive diagnosis

Treatment

If no other source is found for the patient's symptoms of pulsatile tinnitus, treatment of the diverticulum via endovascular coiling, if found on the same side of the patient's symptoms, can provide relief in reducing or eliminating this sound.
