Abstract:
The authors report resection of anaplastic convexital meningioma in a middle-aged woman complicated by expected massive blood loss. The most intense bleeding occurred at the final stage of resection and it was impossible to stop it with traditional approaches. The surgeon pressed a standard tachocomb plate moistened with a diluted solution of recombinant activated factor VII (coagil, Russia) to the most bleeding area for 5 minutes. Subsequently, surgeon replaced finger pressure with a permanent napkin. Hemostatic effect of recombinant activated factor VII following its systemic administration is well known and convincingly proven in many surgical areas including neurosurgery. However, we do not know any descriptions of its local application in neurosurgical patients.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
