A Case of Treatment With Dabigatran for Cerebral Venous Thrombosis Caused by Hereditary Protein C Deficiency.

A 37-year-old woman was admitted to our hospital with involuntary movements. She had no medical or family history of thromboembolism, nor was she on any medication. She showed no impaired consciousness, cranial nerve abnormalities, abnormal breathing, stiff neck or paralysis. Magnetic resonance venography exhibited poor visualization of intracranial vein. The protein C activity level reduced but the protein C antigen level was normal. Genetic analysis revealed a heterozygous mutation in exon 7 c.577-579delAAG, p.Lys193del on protein C gene. She was diagnosed with cerebral venous thrombosis and hereditary protein C deficiency type II. She received heparin in acute phase, and switched to dabigatran in chronic phase. Consequently, she had no recurrence of cerebral venous thrombosis and other complications. Dabigatran might be one of the alternative choices for patients with cerebral venous thrombosis and protein C deficiency.
