Cerebral venous thrombosis (CVT) is caused by various etiologies. In Mediterranean and Middle Eastern countries, Behçet's disease (BD) is one of the leading causes of CVT. We aimed to evaluate any differences in CVT patients with and without BD. All registered patients with CVT were evaluated retrospectively. Clinical, neuroradiological findings and follow-up data were compared between patients with BD and patients with other etiologies. There were 36 patients with CVT and BD, and 32 patients with CVT related to other etiological causes. BD patients were younger (median age at onset 26 vs. 39 years; P < 0.001), and there was a male preponderance (28 males, 8 females) as compared to the non-BD group (10 males, 22 females; P < 0.001). Onset was frequently acute in the non-BD group, and it was subacute or chronic in the BD group. Hemi/quadriparesis, aphasia and seizures were significantly more common (P < 0.001) in the non-BD group. In the BD group 94% of the patients presented with symptoms of isolated intracranial hypertension (P < 0.001). Venous infarcts were observed in 63% of the patients with other causes and in 6% of the patients with BD (P < 0.001). At admission 97% of the patients in the BD group and 41% of the patients in the non-BD group had a modified Rankin score of 0-2. Outcome was good in all of the patients with BD and in 91% of patients with other causes. Clinical recurrences were seen in six patients with BD and in one patient without BD. CVT associated with BD has a subacute onset, mostly presents with signs of isolated intracranial hypertension and venous infarction rarely develops; these features distinguish CVT due to BD from those with other causes.
"Patient with seizures before the diagnosis of NBD had only severe headache. Good prognosis was reported for BD patients with CVT like our patients . The antiepileptic treatment was stopped in two patients while we decided to terminate the treatment in other two patients. "
"Massive subarachnoid hemorrhage might occur in the course of CVT . In one of the 32 cases with CVT caused by other etiologies than Behçet's disease, recurrent lobar hematomas were a remarkable clinical presentation . SDH is an unusual complication of CVT. "
[Show abstract][Hide abstract] ABSTRACT: Spinal subdural hematoma (SDH) is a rare condition and can be caused by several factors. Concomitant cranial and spinal SDH is even much less common. We present a 77-year-old male patient with lower back pain, paraparesis, and urinary retention following a sudden onset headache. Imaging revealed concomitant cranial and spinal SDH related to cerebral venous thrombosis (CVT) associated with hemorrhagic venous infarct. Laboratory examinations were consistent with polycythemia vera. There was no history of trauma and previous cranial surgery. Brain angiography did not reveal any evidence of arteriovenous fistula or vascular malformation. Since lower back pain occurred shortly after the headache and there was no other reasonable explanation for spinal hemorrhage, we suppose that the mechanism of spinal SDH is the migration of blood from the intracranial compartment. Therefore, this is the first report of concomitant spinal SDH and cerebral hemorrhage associated with CVT in a patient with myeloproliferative disease.

[Show abstract][Hide abstract] ABSTRACT: A family of monolithic CRT drivers has been fabricated on a new
high-speed complementary high-voltage process. An example is the LM2406
CRT driver which achieves 40 volt p-p swings in less than 9.5 nsec into
12 pF loads
