Recombinant factor VII (NovoSeven) in intraoperative blood saving during neurosurgical treatment of the brain arteriovenous malformation

Abstract

Background. Cerebral arteriovenous (AV) malformation causes, due to the increased blood flow through a malformation, a massive intraoperative bleeding complicating, so, surgical treatment. The use of intraoperative blood saving apparatus during surgery and a recombinant factor VII-a (NovoSeven) significantly reduce complications during surgical treatment. Case report. We reported a case of surgical treatment of the patient with AV malformation of IV stage according to the Spetzler-Martin scale, in the brain. Due to a possible heavy bleeding we used a apparatus for intrasurgical blood recovery, Cell Saver, Sequestra 1 000, Medtronic, U.S.A., and recombinant human factor VIIa (rFVIIa - NovoSeven, NovoNordisk, Denmark) to control bleeding and restore an adequate hemostasis. Conclusion. The use of an apparatus for intraoperative blood saving, as well as the NovoSeven preparation in the management of AV malformation of IV stage, showed to be successful.
