common carotid artery

A major artery to the head. The left common carotid usually arises from the aortic arch proximal to the left subclavian; the right common carotid is a branch of the brachiocephalic artery. Each common carotid artery runs rostrally in the carotid sheath and enters the neck (behind the sternocleidomastoid muscle) without branching; in the neck, between the level of the top of the trachea and the floor of the mouth, each common carotid artery divides into an internal and an external carotid artery.

A, High-resolution gray-scale sonography revealed a plaque (arrow) in the front wall of the right internal carotid artery, and C, an increase in the intima-media thickness of the left common carotid artery (arrow; the measured value was 1.07 cm).
We introduced the guiding catheter guide wire to the proximal end of the right common carotid artery with continued infusion of heparinized saline, after which we introduced a guide wire with a Cordis stent (10 * 60mm) to completely cover the right common carotid artery dissection site with stenosis and released the stent gradually until it completely filled the stenosis area (Figures 5(a)-5(d))).
CIMT was quantified for right and left common carotid arteries (R-CIMT and L-CIMT, resp.).
CT angiography of the cervical vessels which demonstrated a 50% left common carotid artery stenosis at its bifurcation and an 85% left internal carotid artery sever stenosis
Common Carotid Artery Intima-media thickness (CCA IMT) was observed significantly high throughout group C but it was more profound in Group-C-III.
The regression in maximum left, maximum right, mean left, and mean right common carotid artery intima-media thickness was significantly greater with cilostazol compared with aspirin (_0.088_0.260 versus 0.059_0.275 mm, P_0.001; _0.042_0.274 versus 0.045_0.216 mm, P_0.003; _0.043_0.182 versus 0.028_0.202 mm, P_0.004; and _0.024_0.182 versus 0.048_0.169 mm, P_0.001).
Internal carotid artery (ICA, 36.6%) and common carotid artery (CCA, 19.5%) were most commonly involved, followed by external carotid artery (ECA, 17.1%), vertebral artery (VA, 17.1%), and subclavian artery (SA, 9.8%) [Figure 1].
Ultrasonographic examination of the cervical region revealed the presence of intraluminal calcification at the level of the bifurcation of the left common carotid artery (Figure 2a-c).
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.
(b) Debranching graft's proximal anastomosis was performed end to side to right common carotid artery; graft's carotid leg was anastomosed to left common carotid artery end to end; graft's left subclavian artery leg was anastomosed to the left subclavian artery end to side; and left subclavian artery was simply ligated proximally.
Laboratory tests revealed increased inflammatory markers (erythrocyte sedimentation rate, C-reactive protein) and epiaortic ultrasound showed a significant stenosis of the left subclavian artery and right common carotid artery and a nonsignificant stenosis of abdominal aorta, renal artery, and mesenteric artery.
The common carotid intima-media thickness (cIMT) was determined using conventional ultrasound procedures as measured from the media-adventitia interface to the intima-lumen interface.
