Carotid artery atherosclerotic disease impacts over 2 million Americans annually. Since the advent of the carotid endarterectomy by Debakey in 1953, the surgical management of carotid artery stenosis has prevented cerebrovascular accidents. The technology utilized to manage carotid artery stenosis continued to evolve with the utilization of carotid artery stenting in 1989 and more recently transcarotid artery revascularization (TCAR). This review discusses the modern management of carotid artery stenosis with an emphasis on transcarotid artery revascularization (TCAR) and reversal of flow for reversal of flow for embolic protection.

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.

Background: Carotid artery stenosis (CAS) is a marker of atherosclerosis, a disease mediated by abnormalities in platelet and monocyte function, and a significant cause of stroke. Moreover, the effect of carotid artery revascularization via carotid endarterectomy (CEA) on platelet and monocyte markers is unknown. Objective: This study aims to investigate platelet activity, monocyte subsets and monocyte platelet aggregates (MPA) in CAS and changes with CEA. Methods: This prospective cohort study evaluated 48 patients who underwent non emergent CEA. Peripheral venous blood samples were obtained before, immediately postoperative and at 24 hours postoperative. Twenty healthy subjects served as controls. Platelet surface expression of P-selectin and PAC-1, monocyte subsets, and MPA were assessed using flow cytometry. Three distinct monocyte subsets were measured: anti-inflammatory (i.e. classical CD14 ++ CD16 - ) and pro-inflammatory (i.e. intermediate CD14 ++ CD16 + and nonclassical CD14 + CD16 ++ ) monocytes. Differences between two matched samples and between the study and control groups were statistically analyzed. Results: Compared to healthy subjects, CAS subjects had significantly greater markers of platelet activity (P-selectin [p=0.003] and PAC-1 [p=0.01]), pro-inflammatory monocytes (intermediate [p<0.0001] and nonclassical [p=0.009]) and MPA (p=0.0002). Following CEA, anti-inflammatory monocytes increased and pro-inflammatory monocytes decreased (Figure 1A). Platelet expression of P-selectin and MPA did not change, while PAC-1 transiently increased but then returned to baseline by 24 hours postoperative (Figure 1B &C). Conclusions: Subjects with CAS have elevated markers of thrombosis, inflammation, and their interface. However, only the pro-inflammatory monocytes are significantly reduced following CEA. Future studies investigating the clinical consequences of this reduction are warranted.

A patient of ischemic heart disease (IHD) with additional carotid artery stenosis (CAS) has been distinguished as a high risk group for both heart and cerebral inconveniences following surgical intervention. We aimed to review the outcome of concurrent carotid endarterectomy (CEA) and off-pump coronary bypass graft (OPCABG)in a patient undergoing surgical revascularization for IHD and CAS at our institute.In the vicinity of 2014 and 2016, fifteen patients experienced OPCABG and CEA associatively in a single Surgeon's Practice. Six (40%) patients had a history of myocardial infarction (MI), four (26.66%) had unstable angina (USAP), and three (20%) had USAP together with MI, though two (13.33%) were asymptomatic. Nine (60%) patients demonstrated no neurological manifestations, three (20%) had transient ischemic assaults (TIAs), two (13.33%) experienced stroke, and 1 (6.66%) experienced both. Majority 7 (46.66%) patients had 75-90% carotid artery stenosis and 6(40%) patients experienced right though 8 (53.33%) experienced left CEA and only 1 (6.66%) had bilateral CEA. Five (33.33%) patients were found left main disease (>50% lesion) and 100% patients have had significant Left Anterior Descending (LAD) lesion in this study. Twelve (80%) patients show significant lesion in Right Coronary Artery (RCA) and ten (66.66%) patients had Obtuse marginal (OM) branch disease. CEA was performed before OPCABG in all cases. There were 15 patients (mean age 62.5±2.8 years; 80% were male), two (13.33%) had a perioperative stroke while one of them had TIAs (6.6%). Mean ICU stay was 36.6±4.5 h and patients were released in 10 days. There was no mortality in the early postoperative period and co-morbidity was less significant (6.6% myocardial ischemia, 13.33% atrial fibrillation, 6.66% TIA, 13.33% Stroke). There was 1 (6.66%) postoperative acute renal failure evidenced by raised serum creatinine level. Two (13.33%) patients showed respiratory complications; only 6.6% of them suffered from wound infection. A combined strategy by means of CEA with OPCABG is safe and savvy in view of the satisfactory consequences of morbidity and mortality rates and also short ICU and hospital stay status.Faridpur Med.
