Congenital fibrinogen disorders with repeated thrombosis

Abstract

Congenital dysfibrinogenemia is characterized with undetectable or low fibrinogen level by Clauss assay complicated by bleeding and/or thrombosis. These may lead to a diagnostic problem to some clinicians unfamiliar with this disease. We reported a case of congenital dysfibrinogenemia manifested as hemorrhage, repeated thrombosis, low fibrinogen levels through Clauss assay and but normal levels of fibrinogen through PT-derived tests. In conclusion, to patients with thrombosis complicated by decreased fibrinogen level, clinicians and laboratory physicians should be alert to the possibility of congenital dysfibrinogenemia.
