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.

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 ...
While venous thrombosis of the legs is the most common form, venous thrombosis may occur in other veins. These may have particular specific risk factors: [5] Cerebral venous sinus thrombosis, cavernous sinus thrombosis and jugular vein thrombosis: thrombosis of the veins of the brain and head
Cerebral venous sinus thrombosis (CVST) is a rare form of stroke which results from the blockage of the dural venous sinuses by a thrombus. 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.
Cranial venous outflow obstruction, also referred to as impaired cranial venous outflow, impaired cerebral venous outflow, cerebral venous impairment is a vascular disorder that involves the impairment of venous drainage from the cerebral veins of the human brain. [1] [2] The cause of cranial venous outflow obstruction is not fully understood.
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
