Background: For patients with symptomatic intracranial artery stenosis (sICAS), endovascular treatment has been shown to be feasible and safe in recent studies. However, in-stent restenosis (ISR) risks the recurrence of ischemic stroke. We attempt to elucidate the risk factors for ISR.Methods: We retrospectively analyzed 97 patients with sICAS from a prospective registry trial that included 20 centers from September 2013 to January 2015. Cases were classified into the ISR≥ 50% group or the ISR < 50% group. The baseline characteristics and long-term follow-up were compared between the two groups. Binary logistic regression analyses were identified as an association between ISR and endovascular technique factors.Results: According to whether ISR was detected by CT angiography, 97 patients were divided into the ISR group (n = 24) and the non-ISR group (n = 73). The admission baseline features and lesion angiography characteristics were similar, while plasma hs-CRP (mg/L) was higher in the ISR≥ 50% group at admission (8.2 ± 11.4 vs. 2.8 ± 4.1, p = 0.032). Binary logistic regression analysis identified the longer stents (adjusted OR 0.816, 95% CI 0.699–0.953; p = 0.010), balloon-mounted stents (adjusted OR 5.748, 95% CI 1.533–21.546; p = 0.009), and local anesthesia (adjusted OR 6.000, 95% CI 1.693–21.262; p = 0.006) as predictors of ISR at the 1-year follow-up.Conclusions: The longer stents, balloon-mounted stents implanted in the intracranial vertebral or basilar artery, and local anesthesia were significantly associated with in-stent restenosis. Further studies are required to identify accurate biomarkers or image markers associated with ISR in ICAS patients.Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT01968122.

Purpose: A low ratio of serum eicosapentaenoic acid to arachidonic acid (EPA/AA) has been associated with atherosclerotic disease. Few studies investigate the association of serum fatty acid (FA) composition with the acute ischemic stroke so far. Our aim of this study is to evaluate the relationships between FA composition and stroke subtypes, extra-/intracranial atherosclerotic stenoses, and other cerebrovascular indicators Methods: This study included 154 consecutive patients who were admitted to our hospital because of acute ischemic stroke between April 2011 and March 2012. We examined the FA composition and classical vascular risk factors. We conducted brain MRI/MRA, carotid ultrasonogram, transthoracic echocardiogram, 24hr Holter electrocardiogram, ankle brachial index (ABI) and pulse wave velocity (PWV) in order to evaluate the severity of atherosclerotic change, stroke subtype, and cardiovascular status. Results: The mean value of EPA/AA was 0.33±0.22 in all patients with acute cerebral infarction. The 154 patients in this study (mean age 71 years) were categorized as follows; large artery atherosclerosis (LA; n=57), small artery occlusion (SA; n=48), cardiogenic embolism (CE; n=18), and others (n=31). We found intracranial artery stenosis greater than 50% in 70 patients (45%). The intracranial artery stenosis was associated with low EPA/AA ratio (P=0.013) and low EPA concentration (P=0.013). This association remained significant (P<0.05) after controlling for classical atherosclerotic risk factors. We could not find a significant correlation between FA composition and stroke subtype. However, there was a tendency for the EPA/AA ratio of LA patients to be the lowest among all subtype groups. The EPA/AA ratio was not associated with ABI, PWV, prevalence of arrhythmia, or cardiac function. Conclusions: A low EPA/AA ratio was significantly associated with intracranial stenosis in patients with acute ischemic stroke. This study shows the EPA/AA ratio might be an important marker to reflect the cerebral artery stenosis.

Introduction: Community-based studies that report prevalence of intracranial artery stenosis (ICAS) assessed with magnetic resonance imaging (MRI) are scarce. Hypothesis: We aim to describe the prevalent ICAS using MRI in a general population of Japanese men, and tested the hypothesis that ICAS was associated with conventional cardiovascular risk factors. Methods: The Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA) randomly recruited and examined participants from Kusatsu City, Shiga, Japan in 2006-2008. Among 853 male participants in the follow-up exam (2012-2015), we performed 1.5-tesla MRI. All images were evaluated by two board-certified neurosurgeons (by the Japan Neurosurgical Society) who were blinded to participant clinical background. Each artery was graded as no stenosis, <50% stenosis, <99% stenosis and complete occlusion. We defined any-ICAS as ICAS of any grade and heavy-ICAS as ≥50% stenosis. We used multivariable logistic regression to assess independent association between ICAS and risk factors including hypertension, diabetes mellitus (DM), dyslipidemia, smoking, drinking, obesity (body mass index ≥30kg/m 2 ) and history of stroke. Results: We analyzed 740 men (47-85 years old, mean age 70.0 years) who completed MRI with no missing pertinent information. Thirty-one individuals (4.2%) had history of stroke. We observed at least one lesion of any-ICAS and heavy-ICAS in 30.5% and 6.5% of the participants, respectively. Any-ICAS was most commonly identified in internal carotid artery (21.6% of the entire participants) followed by middle cerebral artery (11.7%). Older age, hypertension, DM, dyslipidemia and prevalent stroke was associated with ICAS. Hypertension and DM were particularly strongly associated with heavy-ICAS (Table). Results were similar when excluding those with stroke history. Conclusions: This is the first study on prevalence of ICAS and its association with conventional cardiovascular risk factors in a general population of Japanese men. The prevalence of ICAS in Japanese men and the association with primary risk factors of cardiovascular diseases are revealed and they could be a target for prevention of stroke.
