Surgery and Hemostasis

Perioperative Complications

Blood coagulation exists to halt excessive blood loss. It is paradoxical that surgery and trauma simultaneously represent major risk factors for both hemorrhagic and thrombotic complications. Kearon and Hirsh estimated that surgery and trauma increase the baseline risk of thrombosis up to a hundred-fold, whereas patients with mild hemophilia who have never bled from stresses of everyday life may bleed vigorously following surgical procedures.
