Abstract:
Objective To investigate the factors affecting the hemorrhagic transformation(HT)and symptomatic intracranial hemorrhage(sICH)in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)of anterior circulation after receiving endovascular treatment(EVT).Methods A total of 193 patients with AIS-LVO of anterior circulation,who were admitted to the Neurology Department of Anyang Municipal People's Hospital of China from January 2023 to November 2024,were enrolled in this study.There were 84 patients in the HT group and 42 patients in the sICH group.The baseline and clinical data,including gender,age,vascular risk factors(history of hypertension,diabetes,coronary artery disease,atrial fibrillation,coronary stent implantation,valve replacement,smoking),stroke history,pre-operative National Institutes of Health Stroke Scale(NIHSS)scores,laboratory indicators(preoperative D-dimer,neutrophil count,lymphocyte count,postoperative total CO2,and CO2 partial pressure),and perioperative indicators(procedure duration,surgical approach,anesthesia type,and preoperative intravenous thrombolysis),were collected.The clinical data were compared between non-HT group and HT group,as well as between non-sICH group and sICH group,and the independent risk factors for HT and sICH after receiving EVT treatment for AIS-LVO of anterior circulation were analyzed.Results The differences in coronary heart disease(x2=8.443,P=0.004),D-dimer(Z=-3.59,P＜0.001),preoperative NIHSS score(Z=-3.752,P＜0.001),surgical time(Z=-2.529,P=0.011),lesion site(x2=9.951,P=0.019),and moderate to severe stenosis or occlusion of other blood vessels(P=0.025)between the HT group and the non-HT group were statistically significant.The differences in the other baseline indicators and clinical data were not statistically significant(all P＞0.05).The multivariate logistic regression analysis showed that preoperative NIHSS score(OR=1.065,95％CI:1.021-1.110,P＜0.003),tandem lesions(OR=2.805,95％CI:1.306-6.024,P=0.008),coronary heart disease(OR=2.963,95％CI:1.421-6.174,P=0.004),and operation time(OR=1.009,95％CI:1.001-1.016,P=0.019)were the independent risk factors for HT after EVT.No statistically significant differences in baseline data,occlusion site,coexisting other vascular stenosis,and perioperative related indicators existed between the sICH group and the non-sICH group.Conclusion Preoperative NIHSS score,tandem lesion,coronary artery disease,and operation time are the independent risk factors for HT in patients with AIS-LVO of the anterior circulation after receiving EVT.
