Abstract

INTRODUCTION: Inherited factor VII deficiency is the most common autosomal recessive inherited bleeding disorder, with an estimated incidence of one per 500 000 cases in the general population. Bleeding manifestations correlate poorly with circulating FVII levels. During pregnancy, increases in FVII levels can occur in women with mild-moderate FVII deficiencies but not in those with severe deficiency.

AIM: We present five pregnant patients with FVII deficiency and describe the management during their pregnancies and peripartum periods.

METHODS: Retrospective analysis of six pregnancies in five women with FVII deficiency followed during pregnancy and delivery at an academic medical centre between January 2013 and December 2019.

RESULTS: Of the five patients, two had severe, one with moderate and two with mild FVII deficiency. Early postpartum haemorrhage (PPH) occurred in two patients. One of the two severe FVII-deficient patients had PPH with a laceration at delivery despite replacement therapy with recombinant factor VII. The other PPH occurred in a patient with mild FVII deficiency who delivered twins by caesarean section under general anaesthesia. Neuraxial anaesthesia was utilized in only one woman with mild deficiency whose FVII level normalized at the end of the pregnancy.

CONCLUSIONS: Management of delivery for women with FVII deficiency should be addressed on a case-by-case basis at centres with expertise in rare bleeding disorders, maternal foetal medicine and obstetric anaesthesiology. These management discussions should factor the patient's bleeding history, third trimester PT, FVII level, multiple gestation and mode of delivery.
