AIM: To assess intrinsic coagulation pathway factors activity and hemostatic markers of endothelial dysfunction in patients with peripheral artery disease (PAD) before and after lower extremity bypass surgery.MATERIAL AND METHODS: 80 patients with PAD Fontaine grade IIB-III were enrolled. 40 patients underwent open aorto-femoral-popliteal repair (group A) and 40 patients - medication (group B). Before and in 3 months after surgery peripheral venous blood samples were collected to assess the activity of factors VIII, IX, XI, von Willebrand factor (VWF), protein C (PrC), and metabolites of nitric oxide II (NO).RESULTS: Increased preoperative activity of VIII, IX, XI, and VWF factors compared with normal values was observed in group A. After 3 months there was an additional increase of VIII and VWF factors' activity. Activity of IX and XI factors remained increased on background of reduced level of NO metabolites. In group B increased activity of IX, XI, and VWF factors was revealed while levels of NO metabolites and PrC were normal.CONCLUSION: Thus, PAD is followed by prothrombotic state especially in patients after surgery. Surgical procedures are associated with more severe hypercoagulation.
