Hemostatic Rescue with rFVIIa in Bernard–Soulier Syndrome Refractory to HLA-Matched Platelet Transfusion

We report the case of a man in his 50’s diagnosed with Bernard–Soulier syndrome (BSS) in childhood who developed refractory gluteal bleeding following a fall accident. The patient underwent four hematoma evacuation procedures and multiple platelet transfusions, including HLA (human leukocyte antigen) -matched platelet concentrates, without achieving sustained hemostatic control. Given the lack of response to platelet transfusion and ongoing bleeding risk, Eptacog Alfa (recombinant activated factor VII; rFVIIa) was administered for 4 days, following the dosing regimen recommended for Glanzmann thrombasthenia in surgical bleeding settings. Hemostasis was achieved shortly after rFVIIa administration, and no further surgical evacuation was necessary. Importantly, no thromboembolic complications occurred despite the use of rFVIIa. This case demonstrates that rFVIIa can serve as an effective adjunctive hemostatic therapy in patients with BSS who are refractory to platelet transfusions. We reviewed the existing literature on rFVIIa use in patients with BSS and summarized the clinical contexts, dosing strategies, efficacy, and safety outcomes. Our experience suggests that early consideration of rFVIIa may help prevent repeated surgical interventions and reduce bleeding-related morbidity in complex cases.
