[Clinical features and diagnosis of cerebral venous thrombosis]
1Neurology of Department, Capital University of Medical Sciences Xuanwu Hospital, Beijing, 100053.
Objective:
To investigate the clinical features and imaging diagnosis of cerebral venous thrombosis.
Methods:
65 cases of cerebral venous thrombosis (CVT) were proved by angiography (n = 34) or MR (n = 44), 30 by both procedures and 6 by pathology as well. Their age ranged from 13 to 59 years (mean age 32.5), 31 were male and 34 were female.
Results:
The clinical manifestations were variable, but most patients had symptoms and signs of intracranial hypertension (91%)such as headache and papilledema. Nearly half of the patients had focal neurological dysfunction (49%) such as weakness of limbs and seizures and half of the patients had intracranial hypertension (51%) only. The occluded dural sinus and the clot could be visualised directly by means of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA).
Conclusion:
MRI and MRA are becoming the imaging investigation of choice for the diagnosis of CVT, Anticoagulation, thrombolysis and dextran may be effective measures in the treatment of cerebral venous thrombosis.
