Objectives: We hypothesized that long-term morbidity and mortality can be identified by the presence of comorbidities in patients with carotid artery stenosis. In our study we aimed to investigate the relationship between clinical characteristics, laboratory findings and long-term prognosis in carotid artery stenosis patients after stenting Patients and Methods: We retrospectively enrolled 212 patients whom underwent carotid artery stenting (CAS) between January 2010 and December 2012 at Kartal-Kosuyolu Training and Research Hospital. CAS was performed in symptomatic patients with >60% stenosis and in asymptomatic patients with >80% stenosis of extracranial carotid artery. Symptoms were defined by an ipsilateral cerebral or ocular minor or major ischemic event within the past 6 months. Results: Mean age of study population was 67.4 ± 7.9 years and 158 patients (74.5%) were male. In the follow-up period 18 patients had MI, 18 patients had major stroke, 23 patients had transient ischemic attack. Twenty-one patients (9.9%) died from cerebral-cardiovascular causes. All MACCE was found in 64 patients (30.2%). Multivariate analysis revealed that age (OR: 1.09, 95% CI: 1.02-1.17, p = 0.05), heart failure (OR: 3.78, 95% CI: 1.48-9.62, p = 0.005), creatinine (OR: 3.54, 95% CI: 1.16-10.82, p=0.026) and neutrophil-lymphocyte ratio (OR: 2.88, 95% CI: 1.90-4.36, p < 0.0001) were independent predictors of the MACCE. Conclusion: Although, the short-term risk of patients undergoing CAS dominated by lesion-related factors, pre-existing comorbidities may be even more important for the long-term event. Age, heart failure, creatinine and neutrophil-lymphocyte ratio were found as the most important risk factors of MACCE.

Objectives Platelet/lymphocyte ratio is considered to be a recent biomarker which is not only related with inflammation but also associated with the atherosclerotic process. In this study, we aimed to investigate the relationship between carotid artery stenosis, platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, and mean platelet volume in patients undergoing carotid endarterectomy. Methods A total of 160 patients (127 males, 33 females; mean age 69.98 ± 9.76 years; range 48–92 years), who were undergoing carotid endarterectomy due to severe carotid artery stenosis, were evaluated and compared with 201 patients (140 males, 61 females, mean age 66.30 ± 9.24 years, range 41–90 years) without severe carotid artery stenosis. The patients were divided into four groups with respect to the carotid artery stenosis as: Group I (<50% stenosis), Group II (50–70% stenosis), Group III (70–90% stenosis), and Group IV (90–99% stenosis). Results Platelet/lymphocyte ratio, neutrophil/lymphocyte ratio and mean platelet volume were found higher in Group IV (patients with severe carotid artery stenosis) (p < 0.01) and were positively correlated with the degree of stenosis (p < 0.01). Platelet/lymphocyte ratio is an independent predictor for post operative stroke (p = 0.047) at multivariate analysis. A threshold level of 145.304 of platelet/lymphocyte ratio combined with a sensitivity 83.3% and specificity 73.8% (95% CI, 0.802–0.921, area under the curve = 0.862 ± 0.03; p = 0.002) for the identification of post operative stroke. Conclusions This retrospective study suggests that platelet/lymphocyte ratio in the blood which was taken preoperatively could be considered as an additional, easy, and inexpensive method to predict a possible higher incidence of postoperative stroke after carotid endarterectomy.

Background: Carotid artery stenosis is an important cause for stroke. Carotid endarterectomy (CEA) reduces the risk of stroke in patients with symptomatic carotid stenosis and to some extent in patients with asymptomatic carotid stenosis. More than 20 years ago, carotid artery stenting (CAS) emerged as an endovascular treatment alternative to CEA. Objective and Methods: This review summarises the available evidence from randomised clinical trials in patients with symptomatic as well as in patients with asymptomatic carotid stenosis. Results: CAS is associated with a higher risk of death or any stroke between randomisation and 30 days after treatment than CEA (odds ratio (OR) = 1.74, 95% CI 1.3 to 2.33, p < 0.0001). In a pre-defined subgroup analysis, the OR for stroke or death within 30 days after treatment was 1.11 (95% CI 0.74 to 1.64) in patients <70 years old and 2.23 (95% CI 1.61 to 3.08) in patients ≥70 years old, resulting in a significant interaction between patient age and treatment modality (interaction p = 0.007). The combination of death or any stroke up to 30 days after treatment or ipsilateral stroke during follow-up also favoured CEA (OR = 1.51, 95% CI 1.24 to 1.85, p < 0.0001). In asymptomatic patients, there is a non-significant increase in death or stroke occurring within 30 days of treatment with CAS compared to CEA (OR = 1.72, 95% CI 1.00 to 2.97, p = 0.05). The risk of peri-procedural death or stroke or ipsilateral stroke during follow-up did not differ significantly between treatments (OR = 1.27, 95% CI 0.87 to 1.84, p = 0.22). Discussion and Conclusion: In symptomatic patients, randomised evidence has consistently shown CAS to be associated with a higher risk of stroke or death within 30 days of treatment than CEA. This extra risk is mostly attributed to an increase in strokes occurring on the day of the procedure in patients ≥70 years. In asymptomatic patients, there may be a small increase in the risk of stroke or death within 30 days of treatment with CAS compared to CEA, but the currently available evidence is insufficient and further data from ongoing randomised trials are needed.

Background: Extra cranial carotid disease due to arteriosclerosis is usually associated with hypercholesterolemia and hyperlipidemia. Extra cranial carotid stenosis has been found to be less prevalent in black American and in Egyptians while intracranial disease is far more common Various methods includes transcranial doppler (TCD) ultrasonography, cerebral angiography, computed tomography angiography (CTA) and magnetic resonance angiography (MRA).Methods: All patients with ischaemic stroke of acute onset admitted in the medical wards of Konaseema institute of medical sciences between June 2018 and January 2019 were included in the study. All patients were subjected to CT scan brain study and colour Doppler study of extra cranial carotid arteries and vertebral arteries. Systolic and diastolic velocity of blood flow, carotid intimal medial thickness, presence of athermanous plaque and thrombus was looked for and then the percentage of stenosis of the affected arteries was calculated.Results: In the present study 0ut of 23 patients with carotid stenosis 9 patients had mild carotid stenosis, 8 patients had moderate stenosis and 6 patients had severe stenosis. Out of 23 patients with carotid stenosis the 11 patients have stenosis in the right carotid and 12 patients had stenosis in the left side. The site of stenosis is ICA in 17 patients and CCA in 6 patients.Conclusions: In present study every patient with carotid artery stenosis had one or the other risk factor for carotid atherosclerosis. In other words, there was no patient with carotid artery stenosis, without any risk factor in present study. Hence asymptomatic patients with these risk factors should be screened for carotid stenosis to prevent stroke.

Revascularization Procedures

Background: Carotid revascularization procedure, carotid endarterectomy (CEA) and carotid stent placement (CAS), are some of the most common procedures performed in United States and expected to change due to wider adoption of CAS. We performed this study to determine the changes in utilization of CEA and CAS in United States using nationally representative data. Methods: We used the National Inpatient Sample (NIS) from 2005 to 2014 to assess the changes in utilization of CEA and CAS over last 10 years in patients with symptomatic and asymptomatic carotid artery stenosis. NIS is the largest all payer dataset that includes diagnoses, admissions and discharge, demographics, and outcomes data of patients admitted to short stay non-Federal hospitals in the United States. We analyzed patterns of changes in utilization in various subsets of patients with carotid artery stenosis. Results: A total of 1,186,182 patients underwent carotid revascularization procedures during study period; 1,032,148 (87.1%) and 154,035 (12.9%) were CEA and CAS, respectively. The overall carotid revascularization procedures decreased over last 10 years (11.1% in 2005 to 8.4%in 2014, trend test p <.0001). Carotid revascularization in symptomatic patients increased (7.64% in 2005 to 11.01% in 2014, trend test p <.0001) while it decreased in asymptomatic patients (92.36% in 2006 to 88.99% in 2014, trend test p <.0001). There was an overall decrease in CEA (11.6% in 2005 to 8.3% in 2014, trend test <.0001) while in CAS remained unchanged (8.1% in 2005 to 8.9% in 2014, p=NS). There was an increase in carotid revascularization in teaching hospitals (40.9% in 2005 to 67.1% in 2014, trend test p <.0001) while decrease in non-teaching hospitals (50.9% in 2006 to 27.1% in 2014, trend test p <.0001). There was a decrease in carotid revascularization procedures in patients aged ≥80 years (19.8% in 2005 to 18.7% in 2014, trend test p <.0001) and CEA (19.6% in 2006 to 18.8% in 2014, trend test P<.0001) and CAS (21.2% in 2006 to 18.6% in 2014, trend test p=<.0001). Conclusion: Although CAS is increasing in a disproportionate manner within patient subgroups in United States, overall carotid revascularization procedures have decreased for unclear reasons.

PurposeTo report the results of a retrospective analysis of prospectively collected data evaluating the safety and efficacy of a double layer stent engineered for carotid artery occlusive disease.MethodsBetween January 2014 and February 2017, 138 patients (25.4% women; median age 71 years) underwent Casper stent implantation for carotid artery stenosis. Eligibility criteria included stenosis >70% of vessel diameter (or >50% diameter with ulceration) in symptomatic patients or asymptomatic patients with >80% stenosis at the carotid bifurcation or in the proximal internal carotid artery. For all procedures, a distal embolic protection device was used. The primary endpoint was the rate of 90 day major adverse neurological events, defined as minor stroke, major stroke, or death by independent neurological assessment.ResultsStent deployment was completed successfully in all cases without documented technical failure. There were no adverse neurological events or mortalities within 90 days. One thromboembolic occlusion of a small distal branch of the anterior cerebral artery occurred during the procedure and resolved with systemic recombinant tissue plasminogen activator administration. New ischemic lesions, all clinically silent, were seen in 6.5% of patients on post-procedure cerebral MRI.ConclusionThe Casper carotid stent demonstrated safety and efficacy in the treatment of carotid stenosis, with no technical failures and no adverse neurological events seen throughout the 90 day follow-up period. Its double layer structure seems to combine adequate plaque scaffolding with high vessel adaptability.
