Abstract:

Objective To investigate the relationship between neutrophil-to-lymphocyte ratio(NLR),transforming growth factor-beta 1(TGF-β1),caveolin-1(Cav-1) and the risk of bleeding after mechanical thrombectomy for acute intracranial artery occlusion in elders. Methods A total of 120 elderly patients with acute intracranial artery occlusion who were treated in Hebei Petro China Central Hospital from September 2017 to December 2021 were enrolled and classified into bleeding group and non-bleeding group according to whether there was postoperative bleeding. The differences in clinical data,NLR,TGF-β1 and Cav-1 levels between the 2 groups were compared. Multivariate Logistic regression analysis was used to evaluate the influencing factors of postoperative bleeding. The values of NLR,TGF-β1 and Cav-1 in predicting postoperative bleeding were evaluated by receiver operating characteristic(ROC) curve. Results The National Institute of Health Stroke Scale(NIHSS) score in bleeding group was 19.91±2.28,NLR and Cav-1 were 7.20±1.12 and(19.29±5.53) ng·mL-1,respectively,which were higher than those in non-bleeding group(P<0.05). The Alberta Stroke Program Early Computed Tomography Score(ASPECTS) was 5.40±0.77,and the TGF-β1 was(20.20±8.28) pg·mg-1,both of which were lower than those in non-bleeding group(P<0.05). NIHSS score and NLR were risk factors for postoperative bleeding(P<0.05),and ASPECTS was protective factor for postoperative bleeding(P<0.05). Based on ASPECTS,NIHSS score and NLR,the area under curve was 0.851,and the sensitivity and specificity were 64.00% and 84.00%,respectively. Conclusions NLR,Cav-1 and TGF-β1 are related to of bleeding after mechanical thrombectomy for acute intracranial artery occlusion in elders,and serum TGF-β1 is the protective factor. They have certain application value in predicting postoperative bleeding.
