Cerebral venous sinus thrombosis (CVST), cerebral venous and sinus thrombosis or cerebral venous thrombosis (CVT), is the presence of a blood clot in the dural venous sinuses (which drain blood from the brain), the cerebral veins, or both.
Management of cranial venous outflow obstruction involves treating the underlying cause, if identifiable, and managing the symptoms. This can include medication to reduce intracranial pressure, anticoagulation therapy to prevent thrombosis, and in some cases, surgical intervention to restore normal venous drainage. [6] [11]
Cavernous sinus thrombosis (CST) is the formation of a blood clot within the cavernous sinus, a cavity at the base of the brain which drains deoxygenated blood from the brain back to the heart. This is a rare disorder and can be of two types–septic cavernous thrombosis and aseptic cavernous thrombosis. [ 1 ]
Current evidence supports transverse-sigmoid sinus junction dural malformations are acquired defects, occurring in response to thrombosis and collateral revascularization of a venous sinus. [ 6 ] [ 1 ] [ 7 ]
Non-traumatic causes of hemorrhage includes: hypertension, cerebral amyloid angiopathy, hemorrhagic conversion of ischemic infarction, cerebral aneurysms, dural arteriovenous fistulae, cerebral venous sinus thrombosis, cerebral vasculitis and mycotic aneurysm. [3] More than half of all cases of intracranial hemorrhage are the result of ...
The transverse sinuses are of large size and begin at the internal occipital protuberance; one, generally the right, being the direct continuation of the superior sagittal sinus, the other of the straight sinus. Each transverse sinus passes lateral and forward, describing a slight curve with its convexity upward, to the base of the petrous ...
What Are the Symptoms of RSV in Older Adults? Symptoms of RSV can range from mild to severe. Dr. Elizalde says that mild RSV symptoms can include a runny nose, sore throat, coughing, sneezing and ...
Venous sinus stenoses leading to venous hypertension appear to play a significant part in relation to raised ICP, and stenting of a transverse sinus may resolve venous hypertension, leading to improved CSF resorption, decreased ICP, cure of papilledema and other symptoms of IIH. [16]
