sinus thrombosis การใช้

• Most cases of cerebral venous sinus thrombosis are due to hypercoagulability.
• Gram-negative rods and anaerobes may also lead to cavernous sinus thrombosis.
• Ludwig's angina and cavernous sinus thrombosis are rare but serious complications of odontogenic infections.
• The relationship between this area and a risk of cavernous sinus thrombosis was described as early as 1852.
• This can result in septic cavernous sinus thrombosis, which is a rare, but life-threatening condition.
• In 1937 a study found that 61 % of the cases of cavernous sinus thrombosis were the result of blood thinners.
• Imaging including angiography may be indicated to identify dural venous sinus thrombosis as a cause of intracranial hypertension and optic atrophy.
• An MR venogram is also performed in most cases to exclude the possibility of venous sinus stenosis / obstruction or cerebral venous sinus thrombosis.
• The "'Tobey Ayer test "'is used for lateral sinus thrombosis by monitoring cerebrospinal fluid pressure during a lumbar puncture.
• In patients with thrombophlebitis of the facial vein, pieces of the clot may break off and enter the cavernous sinus, forming a cavernous sinus thrombosis.
• Neurological involvements range from aseptic meningitis to vascular thrombosis such as dural sinus thrombosis and organic brain syndrome manifesting with confusion, seizures, and memory loss.
• Sinusitis may extend to the central nervous system, where it may cause cavernous sinus thrombosis, retrograde meningitis, and epidural, subdural, and brain abscesses.
• 40 % of people have seizures, although it is more common in women who develop sinus thrombosis peripartum ( in the period before and after giving birth ).
• CNS involvement in Beh鏴t's may lead to intracranial hypertension most commonly due to dural venous sinus thrombosis [ 8-10 ] and subsequent secondary optic atrophy.
• Papilledema as a result of dural sinus thrombosis and atrophy resulting from retinal disease, have been characterized as secondary causes of optic nerve atrophy in Beh鏴t's disease.
• The "'danger triangle of the face "'consists of the area from the corners of the brain causing cavernous sinus thrombosis, meningitis or brain abscess.
• Less Common causes are : Papilledema, Brain tumor or abscess in occipitalregion, Cerebral trauma or hemorrhage, Meningitis Arachnoidal adhesions, sinus thrombosis, Liver Dysfunction or, Late Stage Kidney.
• No increase of cerebrospinal fluid pressure during compression of the internal jugular vein on the affected side, and an exaggerated response on the patent side, is suggestive of lateral sinus thrombosis.
• The CNS is compromised by trichinosis in 10 24 % of reported cases of cerebral venous sinus thrombosis, a very rare form of stroke ( 3-4 cases per million annual incidence in adults ).
• Cerebral venous sinus thrombosis, thrombosis of the veins of the brain, usually causes a headache that reflects raised intracranial pressure and is therefore made worse by anything that makes the pressure rise further, such as coughing.
