Bilateral Vertebral Artery Dissection in a Patient With Afibrinogenemia

Abstract

Background Afibrinogenemia, a rare coagulation disorder, has not been associated with vertebral artery dissections. Case Description A 28-year-old woman with afibrinogenemia developed spontaneous neck pain followed by a right medullary infarction, and MR angiography showed extensive bilateral vertebral artery dissection. She was treated with fibrinogen replacement and anticoagulants and showed a favorable evolution, with only mild residual right upper arm incoordination. Conclusions In this patient spontaneous bilateral vertebral artery dissection complicated afibrinogenemia. Since anticoagulant therapy is usually indicated for arterial dissection, this association created a therapeutic problem. This patient received anticoagulants with fibrinogen replacement, which resulted in a favorable evolution.
