Recanalisation and outcome after cerebral venous thrombosis

Abstract

Little is known of the natural history and rate of sinus recanalisation after cerebral venous thrombosis (CVT). Although acute anticoagulation is effective, the duration of therapy remains speculative. We aimed to determine the relationship between sinus recanalisation and clinical outcome. We studied 12 consecutive patients with aseptic CVT with evidence of sinus thrombosis on initial magnetic resonance imaging, followed up 5-68 months after onset, using 15 repeat magnetic resonance scans in 9 of the patients to assess sinus recanalisation. All patients initially had one or more thrombosed sinuses and were treated with anticoagulants for at least 6 months, including 3 with haemorrhagic infa..
