A patient with undetected haemophilia C and recurrent bleedings during anticoagulant therapy
open access
Abstract
Haemophilia C is an uncommon bleeding disorder caused by XI factor deficiency. The bleeding
intensity depends mainly on patient’s genotype, other coagulation factors activity and platelets
activity, less on XI factor activity so it is possible that asymptomatic illness reveals after anticoagulant
is administered.
The article describes a case of a patient with haemophilia C detected while she was being
diagnosed due to recurrent bleedings during rivaroxaban and vitamin K antagonist therapy.
