Abstract
Cerebral infarction is a serious brain injury disease, which is mainly caused by the blockage of blood circulation in patients' brains; thus, the patient's brain appears ischemia and hypoxia state, and large-scale nerve cell death occurs immediately. The aim of this study was to explore the influence of lower extremity deep venous thrombosis (LEDVT) on coagulation indexes and thromboelastogram (TEG) after cerebral infarction. Altogether, 67 patients with cerebral infarction complicated with LEDVT in our hospital from April 2017 to August 2019 were collected as the observation group (OG) and 58 patients with cerebral infarction without lower extremity deep venous thrombosis as the control group (CG). The R, K, angle, and MA values in PT, APTT, TT, FIB, and TEG indexes were compared between the two groups. The ROC curve was applied to analyze the diagnostic value of R value, K value, angle value, and MA value in the occurrence of LEDVT in patients with cerebral infarction. Logistic regression analysis was applied to analyze the independent risk factors of lower extremity deep venous thrombosis in cerebral infarction. PT, APTT, and TT in the OG were evidently lower than those in the CG, while FIB in the OG was evidently higher than that in the CG, R value and K value of the OG were evidently lower than those of the CG, and angle and MA values were higher than those in the CG. The AUC of R value, K value, angle value, and MA value of the ROC curve of LEDVT in patients with cerebral infarction was 0.735, 0.713, 0.790, and 0.819. Multivariate analysis showed that high FIB, angle, and MA were risk factors, while R and K values were protective factors. PT, APTT, and TT are lower and FIB is higher in patients with cerebral infarction with LEDVT. TEG has a certain diagnostic value. FIB value, angle value, and MA value are independent risk factors of LEDVT in patients with cerebral infarction, while R value and K value are protective factors.
Highlights
Cerebral infarction is a serious brain injury disease, which is mainly caused by the blockage of blood circulation in patients’ brains; the patient’s brain appears ischemia and hypoxia state, and large-scale nerve cell death occurs immediately [1]
67 patients with lower extremity deep venous thrombosis (LEDVT) were obtained as the observation group (OG) and 58 patients with cerebral infarction without LEDVT were the control group (CG). e study was conducted according to the Helsinki Declaration and approved by the Ethics Committee
E TEG parameters R value, K value, angle value, and MA value between the two groups were compared. (3) e diagnostic value of R value, K value, angle value, and MA value of TEG in patients with cerebral infarction with LEDVT was analyzed by the ROC curve. (4) e independent risk factors of LEDVT in patients with cerebral infarction were analyzed by logistic regression
Summary
Received 15 November 2021; Revised 29 November 2021; Accepted 15 December 2021; Published 6 January 2022. E aim of this study was to explore the influence of lower extremity deep venous thrombosis (LEDVT) on coagulation indexes and thromboelastogram (TEG) after cerebral infarction. E R, K, angle, and MA values in PT, APTT, TT, FIB, and TEG indexes were compared between the two groups. E ROC curve was applied to analyze the diagnostic value of R value, K value, angle value, and MA value in the occurrence of LEDVT in patients with cerebral infarction. Logistic regression analysis was applied to analyze the independent risk factors of lower extremity deep venous thrombosis in cerebral infarction. PT, APTT, and TT are lower and FIB is higher in patients with cerebral infarction with LEDVT. FIB value, angle value, and MA value are independent risk factors of LEDVT in patients with cerebral infarction, while R value and K value are protective factors
