title: [Effects of vascular injuries on hemostatic abnormalities in prolonged surgeries of maxillofacial malignant cancer].
abstract: We evaluated the effects of surgical invasion and vascular injury on hemostatic abnormalities in seventeen ASA I-II patients undergoing prolonged surgeries of eight hours or more consisting of tumor excision, radical neck dissection and free flap reconstruction in the maxillofacial region. As molecular markers of blood coagulation and surgical invasion, prothrombin fragment 1 + 2 (F 1 + 2), interleukin-6 (IL-6), tissue-type plasminogen activator (tPA), thrombomodulin (TM) and plasmin alpha 2-plasmin inhibitor complex (PIC) were measured during surgery and on the first and second postoperative days. The F 1 + 2 values increased significantly during surgery and decreased postoperatively, and reached the maximum at the end of surgery. Changes in IL-6 and tPA were similar to those of F 1 + 2, and there was a correlation in the levels of F 1 + 2 and IL-6 (r = 0.54), tPA (0.41) and PIC (0.30) at each measurement time. PIC and TM, however, did not show statistically significant changes intra- and postoperatively, nor was there any correlation between F 1 + 2 and TM values. From these results, we conclude that inflammatory mediators and endothelial stimulation activated by surgical invasion may influence hypercoagulability. Vascular injury, however, did not act as the main coagulation factor during prolonged maxillofacial surgery.
