  • Risk factors associated with carotid endarterectomy

    ObjectiveTo investigate the risk factors of carotid endarterectomy.MethodThe literatures about carotid artery stenosis in the past 30 years were screened through literature retrieval, and the study of surgical risk factors related to carotid artery stenosis were reviewed.ResultsThere were many risk factors associated with the carotid endarterectomy, including demographic, underlying disease, surgical factors, perioperative management, and so on. However, the risk factors analysis were not comprehensive enough in the current study, so there was still lack of effective methods to predict the surgical risk of carotid artery stenosis.ConclusionTo fully understand the risk factors of carotid endarterectomy and to establish a multi-factor prediction model is the direction of further research.

  • Guidelines interpretation of the ISTH guidelines for antithrombotic treatment in COVID-19

    The International Society on Thrombosis and Hemostasis (ISTH) recently released the first ISTH guideline for antithrombotic treatment of COVID-19, which provides recommendations on anticoagulant and antiplatelet agents for patients with COVID-19 in different clinical settings. The target audience includes clinicians in internal medicine, intensive care, infectious diseases, hematology, vascular medicine, residents, family physicians, and other health care providers providing inpatient or outpatient care to COVID-19 patients. This article interprets the important parts of ISTH guideline.

  • Predictive value of the neutrophil-to-lymphocyte ratio in peripheral blood for complications after elective endovascular repair of abdominal aortic aneurysm

    Objective To explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) in peripheral blood for postoperative complications of elective endovascular repair for abdominal aortic aneurysm (AAA). Methods From August 2016 to November 2021, the clinical data of patients with AAA who received endovascular isolation repair for the first time in the Department of Vascular Surgery of Beijing Hospital were retrospectively analyzed, including the basic information of the patients, comorbid diseases, and the largest diameter of AAA, preoperative blood labotry test, postoperative complications, long-term survival rate and other indicators. The optimal NLR in peripheral blood was determined, and the differences in postoperative complications and long-term survival rates between the high NLR group and the low NLR group were analysed. Results A total of 120 patients with AAA underwent endovascular isolation for the first time were included in this study, including 105 males and 15 females. The age ranged from 52 to 94 years, with an average of (73.3 ± 8.26) years. The largest diameter of abdominal aortic aneurysm was 35 to 100 mm, with an average of (58.5 ± 12.48) mm. The best cut-off value of NLR for predicting postoperative complications of AAA was 2.45 by using Yoden index screening. Those with NLR ≥2.45 were in the high NLR group (n=66), and those with NLR <2.45 were in the low NLR group (n=54). There was no statistically significant difference between the two groups in the incidence of overall complications and the incidence of sub-complications (P>0.05). The results of logistic regression analysis suggested that NLR was an independent risk factor for complications after endovascular repair of AAA (P<0.05). The median survival time of patients in the high NLR group and the low NLR group was 31.47 months and 35.28 months, respectively, and there was no statistically significant difference between the two groups (P>0.05). Conclusion NLR can be used as a reference predictor of complications after elective endovascular repair of AAA, but more research results are still needed to confirm.
