Both vertebral arteries were hypoplastic. The patient underwent carotid endarterectomy and, thereafter the episodes of syncope completely disappeared. It was supposed that global ischemia including the brain stem occurred because of stenosis of the left internal carotid artery attributable to the presence ...
Carotid artery disease is a disease in which a waxy substance called plaque builds up inside the carotid arteries1. You have two common carotid arteries (see Figure 1. Common carotid artery), one on each side of your neck. They each divide into internal and external carotid arteries (see Fi...
Figure 1.The common carotid artery divides into the internal and external carotid arteries. The bifurcation (green circle) is the most common site of plaque buildup. What is carotid stenosis? Carotid stenosis is a progressive narrowing of the carotid arteries in a process called atherosclerosis. N...
According to the results of the research, the incidence of internal carotid stenosis was 81%. The incidence of severe stenosis (>70%) was 20%, moderate stenosis (30-69%) was 36%, and mild stenosis (<29%) was 44%. There was a significant relationship between hyperlipidemia, diabetes ...
This is a prospective descriptive research which was carried out in Imam Khomeini Hospital related to Tehran University during two years (1375-1377) in order to study the incidence of internal carotid stenosis in patients who suffered from TIA ot minor stroke. It was evaluated by duplex sonography...
The superimposition of bilateral vertebral artery and contralateral carotid artery occlusion lowered the level of critical stenosis to 72% luminal constriction. When both exter nal carotid arteries were ligated and common carotid artery flow represented internal carotid flow, critical stenosis was determined...
In comparison with the gold standard DSA, DE-CTA-MPR had a slightly better agreement in measuring the degree of stenosis of the internal carotid arteries than CE-MRA. In DE-CTA-PS-MIP images, a systematic overestimation has to be taken into account due to partial extinction of the lumen ...

The aim of this paper was to determine the correlation between calcium burden (expressed as a volume) and extent of stenosis of the origin of the internal carotid artery (ICA) by CT angiography (CTA). Previous studies have shown that calcification in the coronary arteries correlates with signifi...
There were 34 (79%) patients with coronary artery disease and out of them 31 (68%) patients had undergone coronary artery bypass grafting. All patients with common carotid artery, 13 (81%) patients with right internal carotid stenosis and 12 (66%) patients with left internal carotid artery ...
