conclusions the relationship between cac found on dental panoramic radiographs and two cva risk factors--hypertension and mi-- was significant. therefore, it seems that detection of cac on panoramic images of dental patients must be considered by dentists. results among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. in total, 5...

The purpose of this study was to investigate whether the anatomic origin of micro-emboli influences their intracranial distribution. In twenty-two baboons, we examined the distribution of 99-Technetium labelled albumin aggregates (5 to 40 microns in size) after injection into the circulation at the left atrium (LA), carotid trifurcation (CA), and anterior and posterior common carotid artery (CC...

OBJECTIVE To determine site specific carotid intima-media thickness: common-carotid artery and carotid bifurcation in hypercholesterolemia patients as a marker for atherosclerosis. METHODS Fifty patients with hypercholesterolemia and twenty controls were selected after getting informed consent regarding the investigation of carotid- intima media thickness by B-mode ultrasound. All the patient...

This report describes a patient with right-sided aortic arch, aberrant left subclavian artery and Kommerell diverticulum, who presented aneurysmal degeneration of the root to descending aorta, in addition an acute Type B 2-10 dissection. He underwent hybrid treatment valve-sparing replacement, transverse arch replacement reattachment right artery, bilateral common carotid arteries, thoracic end...

BACKGROUND Decreased large artery function, as reflected by increased brachial artery pulse pressure and increased carotid artery diameter and stiffness, may contribute to the increased mortality risk that is observed in subjects with impaired glucose tolerance. We therefore investigated the association between brachial artery pulse pressure and carotid artery diameter and stiffness, which are ...

in this study we investigated the effects of endothelium removal and l-name on responses to α-adrenoceptor agonists. male wistar rats were killed by overdose with pentobarbitone sodium, after which the left and right common carotid arteries were removed. rings of arteries 3-4 mm in length were cut from each vessel and then mounted in 10 ml isolated organ bath, bathed in krebs maintained at 37°c...

Though the variations in the carotid arteries and their branches are common in the carotid triangle, it is important for the clinicians, surgeons and the radiologists to be aware of all possible variations of these arteries. A case of abnormal origin of 2 important arteries encountered during routine dissection of carotid triangle of the neck is reported. The superior thyroid artery that normal...

The results for blood flow in the carotid artery bifurcation on the basis of numerical simulation of Navier-Stokes equations are presented in this study. Four cases of carotid bifurcation are considered: common carotid artery (CCA) bifurcation without stenoses and cases with one, two and three stenoses are also presented. The results are obtained by performing numerical simulations considering ...

BACKGROUND Coronary artery bypass grafting ranks as one of the most frequent operations worldwide. The presence of carotid artery stenosis may increase the stroke rate in the perioperative period. Routine preoperative noninvasive assessment of the carotid arteries are recommended in many institutions to reduce the stroke rate. METHODS 271 consecutive patients undergoing coronary artery bypass...

In a retrospective study, ultrasonic Doppler findings obtained with directional continuous wave equipment were evaluated in 51 patients in whom subsequently the diagnosis of an internal carotid artery occlusion was confirmed by angiography or autopsy. The evaluation was based on the registration of mean velocity analogues of medial frontal (supratrochlear) and common carotid artery blood flow. ...
