CHANGES IN THE INDICATORS OF THROMBUS FORMATION AND FIBRINOLYSIS IN THE PATHOGENESIS OF CEPHALOHEMATOMA IN NEWBORNS

Background. Long-term resorption of cephalohematoma may be accompanied by the formation of surgical complications. The rate of resorption of cephalohematoma has uncertain dynamics and may depend on the characteristics of hemostasis in newborns. Aim. To define the level of thrombus formation and fibrinolysis in venous blood plasma in newborns with cephalohematomas. Methods. There were 90 newborns under observation, 30 – with medium and large-sized cephalohematomas (the cephalohematoma was punctured), 30 – with small-sized cephalohematomas (the cephalohematoma was not punctured). The control group – 30 healthy newborns. The level of thrombosis and fibrinolysis indicators was determined by flow cytometry on a Cytoflex LX device using multiplex analysis kits. Results. On the 10th day, the level of prothrombin in newborns of the first group was 1,33 times higher than in the control group, and 1,47 times higher than in the second group of the study. On the 10th day, the concentration of antithrombin III in the first and second groups exceeded the control group by 5.28 and 8,82 times, and on the 28th day of the study by 6,9 and 7,.28 times. The concentration of type 1 plasminogen activation inhibitor in the first and second groups was higher than in the control group by 3,11 and 5,25 times on the 10th day, and on the 28th day of the study by 2,88 and 3,93 times. The level of D-dimer on the 10th day in the first and second groups was 1,43 and 1,71 times higher, and on the 28th day in both groups it was 1,6 times higher than the control group. Conclusion. Reparation for cephalohematomas is associated with mechanisms of resorption of subperiosteal hemorrhage and depends on the fibrinolytic activity of the hemostatic system. It is likely that the isolation of the cephalohematoma from the systemic circulation under conditions of inhibition of plasminogen activity may be the cause of long-term persistence of subperiosteal hemorrhage.
