Ischemia was induced by permanent occlusion of the middle cerebral artery in rats, via surgical insertion of a nylon filament into the internal carotid artery. (biomedcentral.com)
MRI of the head was performed on postoperative day (POD)1, disclosing cerebral ischemia of the right centrum semiovale and markedly reduced flow in the ipsilateral ICA. (bmj.com)

All patients with symptomatic or asymptomatic internal carotid stenosis for whom open surgery is advised are eligible. (ox.ac.uk)
[1] Approximately 8-10% of patients scheduled for coronary artery bypass graft (CABG) surgery, have significant but asymptomatic internal carotid artery (ICA) stenosis. (ejcvsmed.org)

We studied blood flow distribution in precerebral arteries by assessing flow velocity index in 56 patients with asymptomatic and symptomatic severe carotid stenosis. (oatext.com)
Simultaneous carotid and off-pump coronary artery bypass surgery is safe and effective method of treatment patients with severe concomitant carotid artery stenosis and ischemic heart disease with relatively low mortality rate. (ejcvsmed.org)
In this study we performed a retrospective analysis of safety and efficacy of CEA combined with CABG in patients with severe carotid stenosis requiring CABG surgery. (ejcvsmed.org)
Arteriosclerotic fusiform: caused by severe arteriosclerosis and arterial hypertension. (patient.info)

A patient is described with a right-sided tortuous siphon-like extracranial internal carotid artery leading to highly distressing ipsilateral heart beat synchronous pulsatile tinnitus, scoring 9/10 measuring loudness. (tinnitustalk.com)
Post-operative ICA stenosis secondary to an arterial kinking had been documented in patients who had a tortuous ICA. (irispublishers.com)
The risk of developing thrombosis at the site of PTP remains unknown, and little is known about the efficacy and effectiveness of the above techniques to prevent an arterial kinking stenosis during CEA in the presence of significantly tortuous ICA. (irispublishers.com)
The aim of this study is to present our experience in performing PTP in patients with a tortuous ICA during CEA for their symptomatic carotid disease. (irispublishers.com)
60% stenosis) as well as a significant tortuous ipsilateral ICA. (irispublishers.com)

Hemodynamically significant of internal carotid artery (ICA) stenosis is usually assessed by patterns of local hemodynamic changes in the area of ICA stenosis, which include: an increase peak systolic velocity (PSV), turbulence, pressure gradient, a decrease volumetric blood flow, changed spectrum in the pre- and post-stenotic segments [1-3]. (oatext.com)

Unilateral infarction in the watershed regions, and particularly the internal border zone region, raises the possibility of ipsilateral carotid or middle cerebral artery stenosis ( figure 2 ). (bmj.com)
arterial infarction can be due to either obstruction from thrombosis or embolism or to occlusion from blood vessel abnormalities such as vasculitis. (vin.com)

The exact etiology behind dissecting ICA aneurysms is unknown, although these have been linked to trauma and underlying arterial pathologies, causing a sudden tear in the intimal layer of the artery [3, 6]. (fortunepublish.com)

Carotid artery stenosis is a chronic atherosclerotic disease resulting in narrowing of the common and internal carotid arteries. (lecturio.com)

Traumatic Carotid Cavernous Fistula (TCCF) refers to the rupture of the arterial wall or branches of the cavernous sinus segment of the internal carotid artery caused by trauma, resulting in abnormal arteriovenous communication between the internal carotid artery and the cavernous sinus. (heraldopenaccess.us)
Direct spontaneous carotid-cavernous fistula (sCCF) is reportedly pathognomonic of vEDS. (biomedcentral.com)
It is therefore unsurprising that vEDS has been associated with the development of spontaneous direct carotid-cavernous fistula (sCCF). (biomedcentral.com)

Asahi Intecc Co., Aichi, Japan) was introduced into the common carotid artery. (bmj.com)

An estimated 88% of these are ischemic strokes, with 15% attributed to extracranial carotid occlusive disease. (radiologykey.com)

In about 25% of cases, there is co-existing arterial occlusive disease in the renal or lower extremity arteries. (patient.info)
