[Isolated acquired factor VII deficiency in patient with severe head trauma: use of factor VII (factor VII-LFB].
We report a case of transient acquired and isolated factor VII deficiency associated with severe head trauma. A 16-year-old boy was involved in a motor vehicle accident. CT scan showed frontal brain contusion and a cerebral haematoma (5 cm). First prothrombine time (PT) was normal. Rapidly, a severe coagulopathy developed, unresponsiving to fresh frozen plasma and vitamin K. Haemostatic markers analysis showed an isolated deficiency of factor VII at 15%. No inhibitory activity against factor VII could be detected. We successfully treated the deficiency with intermittent intravenous human factor VII (factor VII-LFB) during 10 days. Factor VII return to normal at 84%. Physiopathological and therapeutic aspects of this rare pathology are presented.
