Epidural blood patching in an anticoagulated patient with intracranial hypotension.

A middle-aged man had classical clinical and radiographical features of spontaneous intracranial hypotension, refractory to conservative management. His medical history included antiphospholipid syndrome, autoimmune thrombocytopenia and recurrent thrombotic events. To reduce his risk from epidural blood patching, we stopped his anticoagulation, but he developed thrombosis.
