ObjectiveTo analyze the influencing factors of hemorrhagic transformation in patients with acute cerebral infarction (ACI) after stent thrombectomy. MethodsA retrospective analysis of the clinical data of 76 ACI patients who underwent stent thrombectomy in our hospital from March 2018 to March 2020 was conducted, and the patients were divided into non-hemorrhagic transformation group (57 cases) and hemorrhagic transformation group (19 cases) according to the presence of hemorrhagic transformation occurrence after surgery. The gender, age, past medical history and other levels of various laboratory test indicators as well were compared between the two groups. Multivariate logistic regression analysis was performed on the risk factors of hemorrhagic transformation after stent thrombectomy in ACI patients. ResultsThere were statistically significant differences in the history of smoking and drinking, hyperlipidemia, atrial fibrillation, large-area cerebral infarction, National Institutes of Health Stroke Scale (NIHSS) score, fasting blood glucose (FBG) level, low-density lipoprotein cholesterol (LDL-C) level, etc. (P＜0.05). The results of multivariate logistic regression analysis showed that atrial fibrillation, large-area cerebral infarction, high NIHSS score, high FBG level, and high LDL-C level were independent risk factors for hemorrhagic transformation after stent thrombectomy in ACI patients (P＜0.05). ConclusionAtrial fibrillation, large-area cerebral infarction, high NIHSS score, high FBG and LDL-C levels are independent risk factors for hemorrhagic transformation after stent thrombectomy in ACI patients.
