    Predictive Values of the CHA2DS2-VASc Score and Left Atrial Diameter for Cerebral Small Vessel Disease in Geriatric Patients With Atrial Fibrillation
    (2023) Tanburoglu, Anil; Karluka, Ismail; Diker, Sevda; Gelener, Pinar; 0000-0002-5760-1777; 37899899; ACL-8451-2022
    Objective The objective of this study was to determine whether the CHA2DS2-VASc (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, age, sex) score and left atrial diameter (LAD) could predict the presence of cerebral small vessel disease (cSVD) in patients older than 65 years with atrial fibrillation as the cause of ischemic stroke. Materials and methods In this study, we included patients over 65 years of age who had suffered an ischemic stroke caused by atrial fibrillation within 30 days after the onset of symptoms. The data recorded included demographics, electrocardiograms, Holter monitors, and echocardiography reports. The anteroposterior LAD, determined by transthoracic echocardiography, was analyzed. Each patient's CHA2DS2-VASc score was calculated. Brain magnetic resonance imaging (MRI) assessed white matter hyperintensities (WMH) on fluid-attenuated inversion recovery (FLAIR) images and cerebral microbleeds (CMBs) on susceptibility-weighted sequences. The Fazekas score, based on WMH on MRI, was used to grade the severity of gliosis. Participants were categorized into three groups according to their quantitative CMB burden. Findings The study included 60 participants, with a mean age of 80 years (range 65-99), and 43.3% (n = 26) were male. The CHA2DS2-VASc score had a mean value of 4.21 (range 2-8), and the mean LAD was 4.17 (range 2.6-5.3) cm. The CHA2DS2-VASc score did not predict CMBs (OR, 1.389; 95% CI, 0.961-2.008, p = 0.08) in geriatric stroke patients with atrial fibrillation. However, in the subgroup of patients with diabetes mellitus, the CHA2DS2-VASc score was higher in those with CMB 1-4 and CMB >= 5 than in those without CMB. Additionally, the risk of CMBs 1-4 increased with higher LAD compared to patients without LAD. Conclusion The LAD and CHA2DS2-VASc scores were not significantly associated with CMB prediction in elderly stroke patients with atrial fibrillation. In a diabetes mellitus subgroup, the CHA2DS2-VASc score was indicative of CMB. An increased LAD elevates the risk of CMBs in patients with coronary artery disease.

    Safety and efficacy of angio-seal use in patients with acute ischemic stroke who received thrombolytic therapy and underwent mechanical thrombectomy
    (2022) Tanburoglu, Anil; Karluka, Ismail; Mazican, Mustafa; Andic, Cagatay
    Purpose: This study aims to evaluate the efficacy and safety of closure of the femoral artery access site using the Angio-Seal Vascular Closure Device in patients who underwent bridging intravenous thrombolytic therapy and subsequent mechanical thrombectomy (MT). Materials and Methods: The retrospective, observational study was performed in patients who were diagnosed with acute ischemic stroke and treated with MT after bridging IVT between September 2018 and September 2021. A total of 97 patients whose femoral artery access sites were closed with Angio-Seal after the procedure was performed were included in the study. Primary demographic data, accompanying risk factors, major and minor complication rates, frequency distributions of categorical variables, and descriptive statistics of quantitative data were calculated and recorded. Results: It was found that 96.9% of the patients did not have major complications, where 97.9% did not have minor complications either. Successful hemostasis was achieved in the groin region in all patients. Major complications observed were recorded as follows: 1 (1%) pseudo-aneurysm, 1 (%) inguinal incision site infection, and 1 (1%) Angio-Seal placement failure. No major complications were observed in 98.2% of those using 6 Fr (French) Angio-Seal and 95.1% of those using 8 Fr Angio-Seal. Conclusion: The findings of the study indicate that Angio-Seal is an effective and safe method for providing groin hemostasis in patients with acute ischemic stroke
