Abstract

Background

Yamakagashi venom is a prothrombin activator, leading to disseminated intravascular coagulation. We report a fatal case of severe coagulopathy from head trauma assumed to be caused by a yamakagashi bite.

Case presentation

An 80-year-old man fell and developed systemic tonic–clonic convulsions. Head computed tomography revealed brain contusion and acute subdural hematoma. Physical examination revealed two bite marks with persistent bleeding on the right lower leg. The patient stated that he had been bitten by some creature 3 days prior, but the bite was left untreated. Laboratory tests showed fibrinogen levels below the detection limit. Although eighteen units of fresh frozen plasma were administered for coagulopathy, fibrinogen levels did not improve. He died about 18 h after a head injury.

Conclusion

In this case of a yamakagashi bite with active bleeding due to trauma, early administration of yamakagashi antivenom should be considered to control coagulopathy.
