OBJECTIVE: The management of intraluminal carotid thrombus is not well defined. Medical and surgical management carry a relatively high risk of thromboembolism. Although endovascular options also carry the risk of thromboembolism from manipulation of the lesion, successful carotid stent placement using various methods of flow restriction has been reported anecdotally. ...

Cardiovascular and cerebrovascular disease are reported to be major risk factors to Alzheimer's disease (AD). These risk factors mainly affect the elderly (over age 60) and previously were believed to only promote vascular dementia (VaD). Cardiovascular and cerebrovascular pathology involving structural lesions of the heart and carotid or vertebral artery ...

Knowledge of carotid bifurcation (CB), common carotid artery (CCA) and its branches and their recognition during diagnostic imaging are also important for vascular surgical procedures in the region, such as carotid endarterectomy or radical neck dissection, catheterization and aneurysms. The surgical anatomy of the carotid arteries was studied in 20 ...

Intrathoracic carotid bifurcation is rare with only five other cases reported. This anatomic variant with posteromedial origin of the internal carotid artery (ICA) appears to be part of the Klippel-Feil syndrome, a rare congenital defect characterized by fusion of the cervical vertebrae. Caution is advised when planning thoracic and cervical ...

BACKGROUND: The resistive index (RI) of the carotid artery is a hemodynamic parameter that depends on the degree of vascular resistance in hypertensive patients. The pulsatility index (PI) of the carotid artery was shown to be associated with microangiopathy in diabetic patients. In contrast to carotid intima-media thickness (IMT), no ...

We present a case of an 83-year-old male without previous history who presented with a cervical hematoma, initially misdiagnosed as a neck phlegmona. In the course of the diagnostic workup, the hematoma enlarged, thereby causing respiratory distress because of upper airway compromise. The endotracheal intubation was lifesaving. Later, contrast enhanced ...

Angioplasty and stenting of the carotid artery has become an accepted procedure in properly selected patients with carotid artery stenosis. The potential for devastating neurologic complications and significant hemodynamic changes separates endovascular treatment of the carotid artery from other percutaneous peripheral vascular procedures. In this article, the technique for carotid ...

Carotid artery disease is the most frequently identified cause of ischemic stroke and is mostly due to atherosclerotic disease. Landmark trials have demonstrated that surgical intervention in cases of high-grade carotid stenosis can reduce the risk of subsequent stroke. Endovascular approaches continue to be evaluated in ongoing trials. Careful patient ...

BACKGROUND: Carotid surgery in asymptomatic subjects with carotid stenosis is effective to prevent ischemic stroke. There is, however, uncertainty how to find such persons at risk, because mass screening with carotid artery ultrasonography (US) is not cost-effective. Signs of carotid bruits corresponding to the carotid arteries may serve as a ...

OBJECTIVE: We sought to determine differences with cardiovascular magnetic resonance (CMR) in the morphology and composition of the carotid arteries between individuals with angiographically-defined obstructive coronary artery disease (CAD, > or = 50% stenosis, cases) and those with angiographically normal coronaries (no lumen irregularities, controls). METHODS AND RESULTS: 191 participants ...

Arteriosclerosis, i.e. degrading arterial elasticity, causes cerebral infarction and myocardial infarction. Premonition of arteriosclerosis is important because arteriosclerosis is never cured completely. We therefore propose a method to track the carotid diameter to evaluate the initial carotid elasticity accompanied with a person's heartbeat using the longitudinal B-mode ultrasonic images. If ...

Severe bradycardia is a common untoward effect during balloon angioplasty when performing carotid artery stenting. Therefore atropine injection even before dilatation and the presence of an anesthesiologist are advocated in all patients. In the surgical literature, injection of a local anesthetic agent into the carotid sinus before carotid endarterectomy was ...
