Autologous blood transfusion in a neurosurgical patient with multiple alloantibodies.

There are many challenges to obtain antigen-negative, crossmatch compatible blood for a patient with multiple alloantibodies. We present a case report of a 31-year-old female patient with a recurrent pontine cavernoma who was to undergo a neurosurgical procedure. We identified alloantibodies anti-Fy^a and anti-c in her blood sample. To meet her intraoperative blood requirement, we attempted with autologous blood transfusion using both predeposit autologous donation and acute normovolemic hemodilution. Autologous blood alone was sufficient despite anticipating surgical blood loss and a postoperative surgical site infection.
