Introduction: Colour Doppler sonography is a well-established widely available,noninvasive, cost effective and a reliable method for assessing cerebrovascular circulation.It has become a valuable completion of the sonographic workup in patients with cerebralischaemia and infarction. Its accuracy is close to angiography. Objectives: To determine thefrequency of significant carotid artery stenosis in patients of cerebral ischaemia/stroke and itscharacterized sonographic appearance of plaque. Study Design: Cross sectional study, basedon nonprobability convenience sample technique. Setting: Department of Radiology, CombinedMilitary Hospital Lahore, using Colour and Power Doppler Ultrasound machine ALOKA SSD-5500. Period: 14 October 2006 to 15 March 2007. Methodology: Total of 50 diagnosed patientsof either gender, aged 30 to 70 years with cerebral ischaemia and stroke were included in thestudy. Carotid Doppler examination was conducted in each patient and findings were recorded.Results: Among 50 patients who underwent carotid Doppler examination for diagnosis ofclinically significant carotid artery stenosis, 35 patients had carotid plaques. 08 patients werediagnosed to have more than 70 % stenosis, 07 patients with more than 50 % and 20 patientsless than 50 % carotid artery stenosis. 15 patients did not show any carotid artery disease.12 patients had bilateral stenosis while 23 had unilateral disease. Mean age of the patientswith and without carotid artery disease was 52 ± 7.87 years. Conclusion: Majority of patientswith Cerebral ischemia/stroke showed carotid artery stenosis on colour Doppler ultrasound.Common age group who developed cerebral ischemia/stroke was above 50years.

Artery Disease

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.

Angioplasty And Stenting

Following the favorable results obtained in the treatment of coronary artery disease, combined angioplasty and stenting has been advocated for the treatment of carotid artery stenosis as well. Although widespread application of angioplasty and stenting for carotid artery disease is neither indicated nor recommended, it may be a viable alternative therapy for select patients who are high-risk patients for surgery. The results of early series have suggested that endoluminal revascularization in these high-risk patients can be performed with an acceptable degree of safety. Although the incidence of death and major stroke rates following angioplasty and stenting procedures compares favorably with surgery, results of more recent clinical series have suggested that the incidence of perioperative transient neurological events and minor strokes may be higher than suggested by earlier reports, especially in patients with recent neurological symptoms and “unstable” plaques. In this article, the authors review the current potential indications for and preliminary results of angioplasty and stenting and describe their procedural technique. In addition, potential applications of stenting to intracranial thromboocclusive carotid artery disease are reviewed.

Coexisting carotid artery stenosis and coronary artery disease is common and there is currently no consensus in treatment guidelines on the timing, sequence and methods of revascularization. We report a case of a patient with symptomatic triple vessel coronary artery disease as well as asymptomatic severe right internal carotid artery stenosis. Our patient underwent myocardial revascularization first, because she presented with unstable angina and was asymptomatic neurologically. This article summarizes current literature about the approach to carotid and coronary artery revascularization and addresses the decision-making process regarding the timing and sequence of revascularization.

Abstract: This chapter discusses the medical and surgical management of carotid artery disease, including both surgical and endovascular revascularization. Surgical treatment for symptomatic cervical carotid artery stenosis is one of the most effective means of preventing ischemic stroke. It has been validated through multiple high-quality prospective surgical trials. There is substantial reduction of stroke risk versus best medical management with treatment of carotid stenosis via carotid endarterectomy. Although endovascular management with carotid artery angioplasty and stenting has emerged as another high-quality treatment, carotid endarterectomy remains the treatment of choice for patients who are of acceptable medical risk for surgery. The details of the carotid endarterectomy procedure and its perioperative management are discussed.

: The management of asymptomatic atherosclerotic carotid artery disease and the role of antithrombotic therapy is of increasing importance for stroke prevention. Non-invasive imaging of carotid plaques can identify high-risk plaque features that are associated with the risk of plaque rupture. Carotid plaque necrosis, hemorrhage, fibrous cap thinning, and the presence of foam cells have all been correlated with the risk of rupture and onset of neurological symptoms in patients with carotid stenosis. Antiplatelets are currently recommended for patients with a history of ischemic stroke and/or significant carotid artery stenosis, with aspirin and clopidogrel being the most widely used and studied agents. The role of dual antiplatelet therapy remains controversial. Moreover, there is scarce evidence on the role of newer anticoagulant agents in stable patients with carotid artery stenosis. In this review article, we discuss the pathophysiology of carotid atherosclerosis, the use of non-invasive imaging for detecting the vulnerable carotid plaque and summarize the existing clinical evidence on the use of antiplatelet and antithrombotic agents in carotid artery disease.

<b><i>Background:</i></b> The coincidence of coronary artery disease (CAD) and carotid artery stenosis (CAS) was observed. However, the association between pre-existing CAD and ischemic stroke (IS) outcome in patients with high-grade CAS remains unclear. We aimed to investigate the association between pre-existing CAD and outcomes of acute IS patients with high-grade CAS. <b><i>Methods:</i></b> From January 1, 2007, to April 30, 2012, we enrolled 372 acute IS patients with high-grade CAS and prospectively observed them for 5 years. Demographic features, vascular risk factors, comorbidities, and outcomes were compared between patients with and without pre-existing CAD. <b><i>Results:</i></b> Among 372 individuals, 75 (20.2%) patients had pre-existing CAD and 297 (79.8%) patients did not have pre-existing CAD. The prevalence rates of hypertension, congestive heart failure, chronic kidney disease, and gout in patients with pre-existing CAD were significantly higher than in those without pre-existing CAD (<i>p</i> = 0.017, <i>p</i> &#x3c; 0.001, <i>p</i> = 0.002, and <i>p</i> &#x3c; 0.001, respectively). The multivariate Cox proportional hazards model revealed that pre-existing CAD was a significant risk factor for a 5-year all-cause mortality in acute IS patients with high-grade CAS (hazard ratio = 2.26; 95% confidence interval = 1.35–3.79; <i>p</i> = 0.002). <b><i>Conclusion:</i></b> Pre-existing CAD was associated with an increased risk of 5-year mortality in acute IS patients with high-grade CAS. Intensive treatment for the pre-existing CAD may reduce long-term mortality in acute IS patients with high-grade CAS.

Background: Extracranial vertebral artery disease is seen in patients with internal carotid artery stenosis although the clinical significance not well understood. Methods: We analyzed data that was collected as part of the Stent-Protected Angioplasty versus Carotid Endarterectomy (SPACE) trial which recruited patients with recently symptomatic internal carotid artery stenosis. We used Cox proportional hazards analysis to compare the relative risk of various endpoints between the three categories of extracranial vertebral artery disease (normal/hypoplastic, moderate/severe stenosis, and occlusion). The multivariate analyses were adjusted for age, gender, basic demographics and severity of carotid stenosis. Results: Of the 1181 subjects who had extracranial vertebral artery ultrasound evaluation, moderate to severe stenosis and occlusion of one of both extracranial vertebral arteries was diagnosed in 152(12.9%) and 57(4.8%) subjects, respectively. During the mean follow up period (±SD) of 22.1±7.1 months 102(8.6%) and 60(5.1%) experienced a stroke or died, respectively. Compared with subjects with normal or hypoplastic vertebral artery, there was a non-significant 30% higher risk of any stroke among subjects with moderate to severe vertebral artery stenosis (relative risk [RR]1.3, 95% confidence interval [CI]0.7-2.3) after adjusting for potential confounders. There was a 40% and 50% higher risk of ipsilateral stroke (RR 1.4, 95% CI0.7-2.5) and death (RR 1.5, 95% CI 0.7-3.1) among subjects with moderate to severe vertebral artery stenosis after adjusting for potential confounders. In Kaplan Meir analysis, the estimated 1 and 2 year stroke free survival for subjects with moderate to severe vertebral artery stenosis was 88% (standard error [SE]2.6%). In comparison, the estimated 1 and 2 year stroke free survival for subjects with normal or hypoplastic vertebral artery was 92.5%(SE0.8%)and 91.6%(SE0.9), respectively. Conclusions: There appears to be an increased risk of stroke and death in patients with symptomatic internal carotid artery stenosis with concurrent asymptomatic extracranial vertebral artery stenosis.
