[A study on the diagnosis and etiology of cerebral venous thrombosis].
OBJECTIVE
To determine the clinical characteristic and common etiologies of cerebral venous thrombosis (CVT) in China.


METHODS
Clinical and neuroimaging data of 91 cases of CVT were analyzed retrospectively.


RESULTS
91 CVT patients (49 men, 42 women), aged from 9 to 57 years, were diagnosed with MRI (78 cases, 85.71%), MRA (37 cases, 40.66%) or DSA (32 cases, 35.16%). 27 cases (29.67%) had a clinical pattern of isolated intracranial hypertension, 56 cases (61.54%) of focal deficits and/or seizures, 3 cases of subacute encephalopathy and 5 cases of cavernous sinus thrombosis. Oral contraceptive was the most common cause, being found in 12 cases (13.19%).


CONCLUSIONS
Understanding of the clinical characteristics of CVT and using of MRI and MRA examination as early as possible is the key in CVT diagnosis. Oral contraceptive is the most common etiology.
