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.
