Surgical revascularization may be beneficial in patients with ischemic stroke caused by intracranial stenosis or occlusion who are ineligible for thrombolysis. Objective To evaluate the outcome of superficial temporal artery to middle cerebral artery (STA-MCA) bypass in ischemic stroke caused by intracranial artery stenosis or occlusion. Methods We retrospectively studied successive case series of 19 patients who underwent surgical treatment between 2013–2017 of STA-MCA bypass. Surgical procedure was performed for the patients with acute ischemic stroke who were ineligible for thrombolysis. Results Of the 19 patients enrolled, symptom aggravation occurred during medical treatment, the patients were ineligible for thrombolysis despite being within 8 hours of symptom onset. Bypass significantly improved National Institutes of Health Stroke Scale scores, mean patient age was 78.05 years (range, 39–78 y). However, male 11 (57.95%) out of nineteen patients were presented with left-sided-lesions while female 8 (42%) had right-sided lesions with significant infarction growth by diffusion weighted imaging achieved, after surgical maneuver. No major complications occurred intraoperatively, in contrast to 2 (10.5%) minor manifestation were suffering minor complications probably they included the remote infarction (posterior cerebral artery territory). Pooled analysis with our patients showed a significant neurological improvement and a good outcome in 13 (68.4%) patients without hemorrhage or any other complication, 6 (31.6%) patients with unfavorable outcome (severe disability 2; vegetative state 4, non of them are died 0;). Conclusion STA-MCA bypass may be beneficial to patients with acute stroke or stenosis in progress who are ineligible for medical therapy. Furthermore, it appears safe when the infarction is small. These findings indicate that STA-MCA bypass could be considered as a treatment option in selected patients with ischemic stroke caused by intracranial stenosis or occlusion.

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: Intracranial artery stenosis is the most common cause of acute ischemic stroke, especially among people in Asia. About its epidemiology, however little is understood. The goal of our research is to establish the prevalence of intracranial artery stenosis in patients with acute ischemic stroke in a tertiary care hospital. Methods: A descriptive cross-sectional study was done in 1006 acute ischemic stroke patients at Affiliated Zhongda Hospital, School of Medicine, Southeast University China from May 2018 to May 2019. Ethical approval was taken from the Ethical review committee of the institution. A convenient sampling method was done. Intracranial artery stenosis was diagnosed when evidence of acute ischemic stroke was found in the territory of approximately 2 50% stenosis identified by Transcranial Doppler ultrasound and confirmed by magnetic resonance angiography or computed tomography. Statistical analysis was done using the Statistical Package for the Social Sciences version 20. Results: The prevalence of intracranial artery stenosis was found in 331 (32.90%) patients at 95% Confidence interval (0.24-0.42%). Among 331 cases the anterior circulation artery stenosis was present on 201 (19.98%) patients, followed by posterior circulation artery stenosis on 80 (7.95%) patients, then anterior plus posterior circulation artery stenosis on 50 (4.97%) patients. Conclusions: Intracranial artery stenosis is one of the most causes of acute ischemic stroke in China. The proportion of anterior circulation artery stenosis was higher than that in the posterior circulation.

AbstractIn-stent restenosis (ISR) represents a major complication after stenting of intracranial artery stenosis (ICAS). Biomarkers derived from routine blood sampling including C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and mean platelet volume (MPV) have been associated with progressive atherosclerosis. We investigated the role of CRP, NLR, PLR and MPV on the development of intracranial ISR and recurrent stroke risk. We retrospectively included all patients who had undergone stenting of symptomatic ICAS at our university hospital between 2005 and 2016. ISR (≥ 50% stenosis) was diagnosed by regular Duplex sonography follow-up studies and confirmed by digital subtraction angiography or computed tomography angiography (mean follow-up duration: 5 years). Laboratory parameters were documented before stenting, at the time of restenosis and at last clinical follow-up. Of 115 patients (mean age: 73 ± 13 years; female: 34%), 38 (33%) developed ISR. The assessed laboratory parameters did not differ between patients with ISR and those without (p > 0.1). While ISR was associated with the occurrence of recurrent ischemic stroke (p = 0.003), CRP, NLR, PLR and MPV were not predictive of such events (p > 0.1). Investigated blood biomarkers of progressive atherosclerosis were not predictive for the occurrence of ISR or recurrent ischemic stroke after ICAS stenting during a 5-year follow-up.

Abstract Background The neutrophil-to-lymphocyte ratio (NLR) has emerged as an inflammatory marker. However, the associations of NLR with intracranial artery stenosis (ICAS) and ischemic stroke remain unclear. This study aimed to examine the associations of NLR with ICAS and ischemic stroke among a large and high-risk population. Methods Participants with records of clinical characteristics were prospectively recruited from the Neurology Department and Health & Physical Examination Center of Qingdao Municipal Hospital. Logistic regression analysis was used to examine the associations of NLR with ICAS and ischemic stroke. Moreover, we also conducted parametric mediation analysis to estimate the effect of NLR on the risk of ischemic stroke mediated through ICAS. Results A total of 2989 participants were enrolled in this study. After adjusting for covariates, NLR (OR = 1.125, 95%CI 1.070–1.183) and ICAS (OR = 1.638, 95%CI 1.364–1.967) were significantly associated with ischemic stroke. Compared with the first quartile NLR, the second, third and fourth quartiles NLR were independent risk predictors for ischemic stroke (P for trend < 0.001); the third and fourth quartiles were independent predictors for ICAS (P for trend < 0.001). The mediation analysis showed that ICAS partially mediated the association between NLR and ischemic stroke, accounting for 14.4% of the total effect (P < 0.001). Conclusions NLR was significantly associated with ICAS and ischemic stroke. Besides, ICAS partially mediated the association between NLR and ischemic stroke.
