Abstract:
【Objective】 To explore the changes of parameters of thromboelastogram (TEG) detection in patients with cerebral infarction and cerebral hemorrhage, and their correlation with routine coagulation indicators, and compare the two methods in detecting coagulation function and status in patients with cerebrovascular disease. 【Methods】 The detection data of 34 cases of cerebral infarction and 102 cases of cerebral hemorrhage, who underwent TEG and routine coagulation test in parallel, in Department of Neurosurgery of our hospital from January 1, 2018 to March 26, 2019 were collected. Fifty healthy subjects, who underwent TEG and routine coagulation tests in the same period, served as the control. The results of TEG and routine coagulation test of the 3 groups were compared and analyzed. 【Results】 Compared with cerebral hemorrhage (group) and the control, R value of cerebral infarction group decreased significantly, while the Angle angle, MA distance, CI value, Fib and D-D levels increased significantly(P<0.05); the K value, Fib, TT, and D-D of cerebral hemorrhage group increased significantly while Angle angle and MA distance decreased significantly compared with other two groups(P<0.05). The R value, K time (min), TT (s), D-D (mg/L), Angle angle (°), MA distance, CI value, and Fib (mmg/L) of cerebral infarction and cerebral hemorrhage group were 5.06±1.71 vs 6.95±4.34, 1.19±0.68 vs 3.43±1.46, 13.89±1.05 vs 18.63±1.25, 1.93±0.25 vs 2.63±0.45, 69.34±10.37 vs 56.54±10.48, 68.34±9.37 vs 54.35±7.48, 2.20±0.31 vs 0.78±0.41, and 380±70.02 vs 354±71.56 (P<0.05). In cerebral infarction group, the R value, APTT, Angle angle, MA, and CI values were positively correlated with Fib (P<0.05); while K time was negatively correlated with Fib ; MA distance with PT/TT; CI value with PT/APTT(P<0.05). In the cerebral hemorrhage group, the R value was positively correlated with PT/APTT; K time with TT; Angle with Fib (P<0.05); R value/K time were negatively correlated with Fib; Angle with TT; CI value with PT (P<0.05). 【Conclusion】 For patients with cerebrovascular disease, there is no correlation between TEG indicators and the D-D level of routine coagulation tests; the Angle angle of patients with cerebrovascular disease is positively correlated with the elevated Fib; and MA distance is more useful for diagnosing cerebral infarction than cerebral hemorrhage. TEG is complementary to routine coagulation test, and can be used as a laboratory index for assessing the severity of cerebrovascular disease.
