Popis: | Few studies have investigated the rates of recanalisation after cerebral venous thrombosis (CVT). Our objective was to investigate the recanalisation rate and to identify predictors of recanalisation in patients with CVT.We included 102 patients with confirmed first-ever, non-septic CVT. All patients received anticoagulation for 12 months or until complete recanalisation. To assess recanalisation, patients underwent MR venography every 3 months until partial or complete recanalisation or for 12 months after diagnosis. We conducted two parallel analyses of complete recanalisation versus partial and no recanalisation versus any recanalisation. As a secondary objective we explored the influence of recanalisation on outcome and recurrent events. We calculated the probability of recanalisation using Kaplan-Meier analysis and conducted multivariate analysis using a Cox model.The mean age of patients was 33.5±11 years (80 (78.4%) women). Survival analysis indicated that 50% of the patients had any recanalisation (grades I, II and III) by 64 days and complete recanalisation (grade III) by 169 days. Adjusted Cox proportional model revealed that age50 years (HR=11.5 95% CI=1.58 to 84.46, p=0.01) and isolated superior sagittal sinus thrombosis (HR=0.39, 95% CI=0.14 to 1.04, p=0.05) predict complete recanalisation, while age50 years (HR=4.79; 95% CI=1.69 to 13.5, p=0.003) predicts any recanalisation. Patients with complete recanalisation had a greater chance of good functional outcome (HR=5.17; 95% CI=2.8 to 9.53, p0.001).We found that recanalisation occurs over time, until month 11. Complete recanalisation may influence functional outcome. |
