Thromboembolic complications, such as deep venous thrombosis and pulmonary embolism, are well recognized in patients with inflammatory bowel disease (IBD). We describe three cases of cerebral venous thrombosis complicating ulcerative colitis. Cerebral venous thrombosis is a rare but potentially devastating complication of IBD, and the diagnosis needs to be considered in any patient with IBD presenting with neurological symptoms.

Cerebral venous thrombosis (CVT) and deep vein thrombosis or pulmonary embolism (DVT/PE) are associated with many risk factors. It is unclear why CVT occurs less often than DVT/PE. Age dependent risk factors may play a role. The aim of our study was to compare risk factors in a uniform age group of CVT and DVT/PE patients aged between 15 and 50 years. Thrombophilic markers and clinical risk factors of 79 CVT patients and 173 DVT/PE patients aged 15-50 years were compared. Multivariable logistic regression analysis was performed to investigate if risk factors were independently associated with CVT or DVT/PE. Cerebral venous thrombosis patients were younger (median age 30 years vs. 42 years; p<0.001) and more often female (82% vs. 52%; p<0.001). There were no differences in thrombophilic markers. Cerebral venous thrombosis was less often associated with trauma, immobilisation or surgery than DVT/PE (6% vs. 21%; adjusted OR 0.29; 95%CI 0.10-0.82). In women, CVT was more frequently associated with oral contraceptive use, pregnancy or puerperium (82% vs. 53%; adjusted OR 2.34; 95%CI 1.03-5.32). This study demonstrated no differences in thrombophilic markers between CVT patients and DVT/PE patients aged between 15 and 50 years, while the frequency of some transient risk factors was different. Cerebral venous thrombosis was relatively more common in women and hormonal factors may predispose to CVT compared to DVT/PE, while trauma, immobilisation and surgery may be less important in the pathophysiology of CVT.

The benefit of asparaginase for treating acute lymphoid leukaemia (ALL) has been well established. Native asparaginase derives from Escherichia coli (colaspase) or Erwinia chrysanthemi (crisantaspase); in a third preparation, colaspase is pegylated. Depletion of asparagine leads to decreased synthesis of procoagulant, anticoagulant, and fibrinolytic proteins, with resultant hypercoagulability and greater risk of venous thromboembolism (VTE). Colaspase and crisantaspase are not dose-equivalent, with crisantaspase displaying haemostatic toxicity only at dosages much higher and administered more frequently than those of colaspase. Cerebral venous thrombosis and pulmonary embolism are two life-endangering manifestations that occur during treatment with asparaginase particularly in children and in adults with ALL, respectively. Approximately one-third of VTEs are located in the upper extremities and are central venous line-related. Other risk factors are longer duration of asparaginase treatment and concomitant use of prednisone, anthracyclines, and oral contraceptives. The risk associated with inherited thrombophilia is uncertain but is clearly enhanced by other risk factors or by the use of prednisone. VTE prevention with fresh frozen plasma is not recommended; the efficacy of antithrombin (AT) concentrates has occasionally been reported, but these reports should be confirmed by proper studies, and AT should not be routinely employed. Therapeutic or prophylactic heparin doses are only partially effective, and direct thrombin or factor Xa inhibitors could play significant roles in the near future.

Cerebral venous thrombosis (CVT) is an uncommon cause of stroke with extremely diverse clinical features, predisposing factors, brain imaging findings, and outcome. Anticoagulation is the cornerstone of CVT management, however, it is not supported by high-quality evicence. Novel oral anticoagulants (NOACs) have been extensively studied in patients with deep vein thrombosis, pulmonary embolism and non-valvular atrial fibrillation. The aim of our work was to review the available evidence for NOACs in the treatment of CVT. Based on our literature search there is insufficient evidence to support the use of NOACs in CVT, although case series with rivaroxaban and dabigatran have showed promising results.
