Managing menorrhagia in a familial case of factor V deficiency

Factor V deficiency is a rare coagulation disorder. Excessive uterine bleeding is common in affected women. We describe a case of 2 siblings with Factor V deficiency and menorrhagia who achieved control of bleeding with differing treatments.

Patient 1 is a 16-year-old female with Factor V deficiency and menorrhagia which was previously controlled with oral contraceptives (OC). She developed heavy bleeding treated with fresh frozen plasma, anti-inhibitor coagulant complex (AICC), and OC taper. A levonorgestrel IUD was placed with good control of her menorrhagia. Patient 2 is the 12-year-old sister of Patient 1. She was treated with AICC, aminocaproic acid, and her menorrhagia was ultimately controlled with continuous OCs.

Factor V deficiency is a rare cause of menorrhagia. Various treatment modalities are available. In these adolescent sisters desiring future fertility, menorrhagia was managed with OCs and an IUD.
