Abstract
Aim. To assess the changes in endothelial dysfunction in patients undergoing cardiac surgery with minimally invasive extracorporeal circulation (MiECC).
Methods. The study included 50 patients who were undergoing coronary artery bypass grafting (CABG) surgery with cardiopulmonary bypass (CPB). The patients were divided assigned to either a minimally invasive cardiopulmonary bypass system (group 1, n=15) or standard extracorporeal circuit (group 2, n=35). Changes in the laboratory parameters were assessed 5 times: before the operation, 5 minutes after protamine sulfate administration, 12 hours after the operation, 7 days after the patient's discharged from the hospital and one month after the operation. The activity of von Willebrand factor, factor VIII, and the number of activated platelets were examined in all patients in venous blood.
Results. After protamine sulfate administration, the activity of von Willebrand factor was increased to 164% in the group 1, and up to 193% in the group 2, with a tendency to increase the indicator after 12 hours. The peak of endothelial dysfunction, with the growth of von Willebrand factor and factor VIII, occurs on the 7th day after the operation. In patients of the group with MiECC, von Willebrand factor activity was decreased at the hospital discharge and returned to normal in 1 month. The number of activated platelets increases mainly in group 2 (6% versus 4% in group 1, p=0.29). The expression of P-selectin was significantly higher in group 2 at the hospital discharge (5.5% versus 3.1% in group 1, p <0.001), and in 1 month (4.5% versus 2.3% in group 1, p <0.001).
Conclusion. In patients with minimally invasive cardiopulmonary bypass, platelet activation decreases, endothelial dysfunction, accompanied by an increase in the von Willebrand factor and factor VIII activity, is less pronounced; the seventh day after surgery is a period of the high risk of thrombogenic complications.
