[Intracranial venous thrombosis: a study of 16 cases and a review of the literature].


INTRODUCTION The clinical picture and aetiology of intracranial venous thrombosis are highly variable. Early descriptions reported it as a rare disease with a poor prognosis but the advent of neuroimaging techniques, and a deeper knowledge of the clinical picture, have shown it to have a higher frequency and a better prognosis. OBJECTIVE To report the clinical and neuroimaging findings in patients diagnosed as having intracranial venous thrombosis in our department and review the state of the literature. PATIENTS AND METHODS We reviewed all discharge reports from patients admitted to the neurology department of the Juan Canalejo Hospital between 1975 and 2000. Of these, we reviewed the medical records of those patients diagnosed as having intracranial venous thrombosis in order to obtain data relating to the clinical manifestations, complementary tests, etiological and topographical diagnosis, treatment and outcome. RESULTS Diagnosis of intracranial venous thrombosis was made in 16 patients. The most common symptom was headache. The superior sagittal was the most frequently affected sinus. In almost all patients CT results led to the suspicion, and in some cases the confirmation, of the diagnosis. The most frequently found aetiology was oral contraceptive consumption. Outcome was generally good both with anticoagulation and symptomatic treatments. CONCLUSIONS The most important difference between the present study and earlier reports is in the frequency of the different aetiologies. Our findings provide further evidence that intracranial venous thrombosis is not an infrequent disease and that the prognosis is generally good.
