BACKGROUND The anatomy of carotid stenosis may influence the outcome of endovascular treatment or carotid endarterectomy. Whether anatomy favors one treatment over the other in terms of safety or efficacy has not been investigated in randomized trials. METHODS In 414 patients with mostly symptomatic carotid stenosis randomized to endovascular treatment (angioplasty or stenting; n = 213) or ca...

OBJECTIVE Ischemic stroke and hyperperfusion (HP) are the most frequent and important complications in carotid artery stenosis surgery. Carotid artery stenting (CAS) has replaced carotid endarterectomy in high medical risk patients. Prior to CAS, initial angiographic findings disclose a small caliber internal carotid artery (IC) due to stenosis, but after the stenosis is relieved, the diameter ...

BACKGROUND Sickle cell anemia is one of the commonest causes of stroke in children. It is usually, but not always, associated with intracranial vasculopathy. We have assessed the value of ultrasound screening for extracranial internal carotid artery disease. DESIGN AND METHODS Using Doppler ultrasound scanning, we assessed peak systolic blood velocity, tortuosity and stenosis in the extracran...

To investigate how cognitive impairment is affected by the relief of bilateral carotid stenosis, chronic cerebral hypoperfusion was established through stenosis of the bilateral carotid common artery in adult Sprague-Dawley rats. Subsequently, the model rats received the intragastric placebo, donepezil (5 mg per kg), or surgery to relieve carotid stenosis after bilateral carotid common artery s...

BACKGROUND AND PURPOSE Eccentric stenosis of the coronary artery is associated with plaque disruption and acute coronary syndrome. The purpose of the present study was to determine whether eccentric stenosis of the carotid artery contributes to cerebrovascular events. MATERIALS AND METHODS Of 6859 patients with vascular diseases who underwent duplex carotid ultrasonography, we studied 512 int...

Background: Carotid artery stenosis occurs in 8–13% of patients with degenerative aortic stenosis. The risk of new postoperative stroke after cardiac surgery is thought to be twoto four-fold higher in patients with concomitant carotid stenosis. We evaluated the results of carotid stenting in patients with aortic valve stenosis. Methods: We retrospectively analysed internal database containing p...

A 58-year-old man presented for re-evaluation of an asymptomatic right-sided carotid stenosis. Besides conventional ultrasound techniques, we could confirm a moderate right internal carotid artery stenosis by the innovative inverse fly-through technique (figure). Regular checkups were initiated. There is growing evidence that 3D ultrasound may provide new possibilities for evaluating carotid di...

BACKGROUND Carotid endarterectomy is the most common surgical procedure used to treat stenosis of the extracranial precerebral carotid artery. Data from several randomized controlled trials are available to help guide its use in specific patient subgroups. Carotid angioplasty with stenting is also being performed, and clinical trials comparing this procedure with carotid endarterectomy are in p...
