N2 - BACKGROUND: For the reduction of cardio- and cerebrovascular events in carotid endarterectomies continuation of antiplatelet medication is recommended perioperatively. As a result, this patient population is at increased risk for postoperative bleeding complications. Intraoperative application of local hemostatic agents might reduce the incidence of bleeding complications.MATERIAL AND METHODS: All 565 patients undergoing carotid endarterectomy between January 2005 and January 2011 were analysed retrospectively. Most patients in the earlier cohort years of the study had no perioperative antiplatelet medication. In contrast antiplatelet medication was usually continued perioperatively in the later cohort years. To reduce the risk of perioperative bleeding local hemostatic agents were applied increasingly.RESULTS: Revision surgery, due to postoperative bleeding or massive hematoma, was necessary in 20 cases (3.5 %). Overall, 383 carotid endarterectomies (67.8 %) were performed with perioperative antiplatelet medication. Local hemostatic agents were applied in 259 cases (45.8 %) intraoperatively. Initially, operations performed in patients taking antiplatelet medication resulted in an increased need for surgical revision. Following an accelerated practice of using local hemostatic agents, the need for revision surgeries fell. Nevertheless, when patients from all years were analysed together there was no significant benefit from the application of local hemostatic agents.CONCLUSION: Application of local hemostatic agents might have contributed to a reduction of bleeding complications in carotid endarterectomies. However, this could not be shown of statistical significance. Other confounding factors such as different operative techniques or forms of anesthesia might also have influenced this decline.
