Aim. To describe thrombosis of the sinus durae matris (TSDM) in lymphomas. Subjects and methods. 402 patients with Hodgkin lymphoma were treated using the ВЕАСОРР-14 protocol in 2006 to 2013. Thrombotic events occurred in 6% of the patients, including 3 (0.8%) who developed brain magnetic resonance imaging-verified TSDM. Results. TSDM developed in 3 women aged 17, 18, and 25 years during 3-6 chemotherapy cycles involving glucocorticosteroids in a dose of 80 mg/m2 on days 1-7 and an oral contraceptive used continuously for 1.5-3 months. The symptoms of thrombosis were severe headache; 2 patients had convulsive syndrome with short-term loss of consciousness. Anticoagulant therapy with intravenous heparin 20,000-24,000 U/day led to thrombus recanalization within 4-10 days. No rethromoboses were observed during a subsequent follow-up. Conclusion. The ВЕАСОРР-14 treatment in young women with Hodgkin lymphoma who continuously take oral contraceptives should be combined with anticoagulant therapy, by monitoring their coagulogram.
