Post‐lumbar puncture cerebral vein thrombosis

Le résumé fourni par la source

Lumbar puncture (LP) is rarely complicated by cerebral vein thrombosis (CVT), especially if other risk factors coexist. We describe the case of a 28-year-old woman who developed CVT after corticosteroid treatment and LP performed for suspected multiple sclerosis. The day after LP, she developed intense headache and on Day 8 generalized tonic-clonic seizures. A brain computed tomography scan showed thrombosis of the superior sagittal sinus and cortical veins. Thrombophilia screening showed heterozygous G20210A prothrombin mutation. Anticoagulant therapy with low molecular weight heparin and then warfarin was administered until Day 16 after LP, when a brain magnetic resonance imaging showed a subdural hematoma. Warfarin was interrupted and dabigatran was started. The patient recovered completely, both from the initial thrombotic event and the hemorrhagic complication. This case highlights the importance to keep in mind CVT in the differential diagnosis of post-LP headache not responsive to standard therapy, and suggests that dabigatran can be considered an effective and safe treatment of CVT.
