[Factor XI deficiency, a new way of substitution: human purified concentrates]
Case report of a 26-year-old patient, admitted for severe craniofacial trauma, with facial injuries and intracranial haemorrhage. Preoperative tests showed an aPTT = 64 s (control = 29 s), rapidly recognized as being caused by a major constitutional factor XI deficiency (0.06 Ul.mL-1). Considering the neurological risk and the indication for surgery, concentrates of factor XI were administered at a dosage of 25 Ul.kg-1. This treatment was associated with a biological normalization and uneventful surgery. In patients experiencing a factor XI deficiency, the use of fresh frozen plasma will probably decrease and only administered in emergency cases when factor XI concentrates are not available.
