[6] [9] In children, head and neck infections and acute systemic illnesses are the primary cause of central venous thrombosis. [6] Cerebral venous sinus thrombosis is more common in particular situations. 85% of people have at least one of these risk factors: [3]
Dural venous sinus thrombosis (DVST) and cortical venous thrombosis (CVT) commonly presents with headache, increased intracranial pressure, or seizures. DVST is more common than CVT. DVST are frequently caused by infections in the skull base, dehydration, thrombophilia, meningioma, and other dural tumours. [3]
A ventriculoperitoneal shunt may be required in some infants. A pediatric cardiologist should be consulted to manage high-output failure, if present. Often patients need to be intubated. In most cases, the fistulous arteries feeding into the Vein of Galen must be blocked, thereby reducing the blood flow into the vein. [10]
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]
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
An MR venogram is also performed in most cases to exclude the possibility of venous sinus stenosis/obstruction or cerebral venous sinus thrombosis. [5] [7] [8] A contrast-enhanced MRV (ATECO) scan has a high detection rate for abnormal transverse sinus stenoses. [15]
Thrombosis of the great cerebral vein is a form of stroke due to a blood clot in the vein. It affects just 3 to 8% of patients, predominantly women. [ 9 ] Patients may present with consciousness problems, headaches, nausea, visual defects, fatigue, disturbance of eye movements and pupillary reflexes, or coma. [ 9 ]
More common in adults than in children, intraparenchymal bleeds are usually due to penetrating head trauma, but can also be due to depressed skull fractures. Acceleration-deceleration trauma, [ 24 ] [ 25 ] [ 26 ] rupture of an aneurysm or arteriovenous malformation (AVM), and bleeding within a tumor are additional causes.
