Hemostasis can be considered as reflecting a balance of procoagulant and anticoagulant forces. (A) In normal individuals, these forces are in balance, and this acts to prevent overt bleeding or thrombosis. (B) In some pathological states, a relative reduction in procoagulant forces or an excess of anticoagulant forces, can lead to a hemostasis disbalance and bleeding. (C) In some pathological states, an excess of procoagulants forces, or a relative reduction in anticoagulant forces, can lead to a hemostasis disbalance and thrombosis.
