摘要

Congenital hypodysfibrinogenemia is characterized by the synthesis of an abnormal fibrinogen molecule that does not function properly when converting fibrinogen into fibrin. The functional defects include: abnormal fibrinopeptide release, defects in fibrin polymerization, abnormal fibrin stabilization, and resistance to fibrin lysis. The most common hypodysfibrinogenemias are those causing polymerization defects. In most cases, congenital hypodysfibrinogenemia is inherited as an autosomal dominant trait with high levels of penetrance, but some patients show an autosomal recessive inheritance. Clinically, patient with hypodysfibrinogenemia will have one of the following phenotypes: no hemor-rhagic symptoms, mild bleeding following trauma, thrombosis, or both thrombotic and hemorrhagic symptom manifestations (1). Approximately, 43% of all individuals with congenital hypodysfibrinogenemia are asymptomatic, while about 20% have bleeding symptoms and 17% experience thrombotic manifestations. About 20% of patients have a combination of bleeding and thrombosis (2). Women with congenital hypodysfibrinogenemia are at greater risk of obstetric complications.
