For the evaluation of the prevalence of carotid stenosis
, all participants (≥40 years) underwent bilateral carotid duplex sonography in a supine position by expert operators who were blinded to the goal of the study, clinical data, and laboratory findings.
Among the 60 patients 41% (68) had unilateral extracranial stenosis of which 19 (31%) showed unilateral intracranial stenosis, 1 (2%) showed bilateral intracranial stenosis and had middle cerebral artery territorial stroke on the side of intracranial internal carotid stenosis
. 21 patients (35%) did not show stenosis in the intracranial part of internal carotid artery.
[1,21] Our results showed that the patients with ischemic heart disease or carotid stenosis
had more frequently progressing neurological deficits than those without these diseases.
Unilateral carotid stenosis
was present in 49 cases, bilateral stenosis was found in 39, and the contralateral carotid artery was occluded in 12 cases (Figure 1).
Upon review of the medical records (including baseline and clinical characteristics), the candidates for this study were recruited from among the patients with symptomatic, moderate, or severe carotid stenosis
with atherosclerotic etiology, treated between January 2003 and March 2010 at the Department of Neurology of Southwest Hospital, which is affiliated to the Third Military Medical University.
Next, we had to choose a type of treatment for severe symptomatic carotid stenosis
. Because of the contralateral internal carotid occlusion, endarterectomy was not possible, although patients with symptomatic internal carotid artery stenosis of 70-99% are recommended to undergo carotid endarterectomy for the prevention of ischemic stroke recurrence (Class I indication).
Retinal artery occlusion and ischemic optic neuropathy may also be related to carotid stenosis
, as mentioned above.
in itself with altered blood flow around the area of stenosis would cause increased risk of FFT.
 reported bilateral occipital infarcts associated with carotid stenosis
in a patient with a PTA.
We describe a successful hybrid treatment for a proximal critical lesion of the innominate and left common carotid artery in a high-risk patient with a tandem symptomatic right internal carotid stenosis
and a concentric vulnerable plaque in the bicarotid common trunk.

Several studies have shown benefit of carotid endarterectomy (CEA) in symptomatic (i.e., ipsilateral stroke or TIA) and asymptomatic patients with carotid stenosis
. There are two major trials to date that compare the benefit of CEA versus medical management in primary prevention of stroke in patients noted to have carotid stenosis
