Sixty-six of 77 patients(85.7%)had no neurological sequelae during follow- up.Eleven patients(14.3%)remained neurologically impaired.Two who initially presented with isolated intracranial hypertension had blindness due to optic atrophy.The other 9 had focal signs at the time of CVT and were left with various cognitive or focal deficits.Four of 28(14.3%) patients who had seizures at the acute stage had recurrent seizures.One of the 51 patients with lateral sinus thrombosis developed a dural arteriovenous fistula.Nine of the 77 patients(11.7%)suffered a second CVT, all but one in the first year.Noncerebral thrombotic events occurred in 11 patients(14.3%).No recurrence of CVT occurred during later pregnancies,but 1 patient had a postpartum deep vein thrombosis.In the present series,CVT has an essentially good long-term prognosis.The frequency of long-standing epilepsy was low,suggesting that long-term anticonvulsant treatment is not necessary in the majority of cases.A second CVT or another thrombotic episode occurred in 20%of patients,stressing the need in a minority of cases for long-term anticoagulation. |
