OBJECTIVE Common carotid artery intima-media thickness (IMT) is considered a factor of cardiovascular risk and an early marker of coronary artery disease. This study aimed to investigate the existence of a correlation between IMT in the carotid arteries and at the origin of the right subclavian artery, as well as to evaluate IMT in the subclavian artery as an earlier marker of cardiovascular ri...

BACKGROUND Carotid artery stenting has recently been recommended as an alternative to carotid endarterectomy by some clinicians. OBJECTIVE To evaluate success rate, as well as in-hospital and 30-day adverse events in our first experience in Iran for carotid artery stenting with protection devices. METHODS From December 2003 through July 2004, we performed 12 consecutive (9 males and 3 femal...

OBJECTIVES We aimed to determine the relationship between carotid intima-media thickness (IMT) and brachial artery flow-mediated dilation (FMD) in healthy middle-age men. BACKGROUND Carotid IMT and brachial artery FMD are frequently used as surrogate measures of subclinical atherosclerosis. Whereas carotid IMT identifies early structural abnormalities, brachial artery FMD, considered a bioass...

Controversy exists concerning the best management of patients with coronary artery and carotid artery disease. Between June 1994 and July 2000, 88 patients with coronary artery and carotid artery disease underwent combined coronary artery surgery and carotid endarterectomy. Demographics and perioperative variables of these patients were compared with those of 266 patients undergoing isolated co...

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...

Background and Purpose: Ischemic episodes distal to an internal carotid artery occlusion are common. We undertook this study to look for evidence of transhemispheric passage of embolic material in this patient category as a mechanism for embolic events. Methods: Seven symptomatic patients with unilateral internal carotid artery occlusion and contralateral stenosis were examined by transcranial ...

BACKGROUND Conflicting information exists regarding the association between hsCRP and the progression of early stages of atherosclerosis. The purpose of the study was to investigate the association of high sensitiviy c-reactive protein (hsCRP) along with major cardiovascular (CV) risk factors on early carotid atherosclerosis progression in a large, population-based cohort study. METHODS The s...

BACKGROUND AND PURPOSE Many patient monitoring techniques have been used for detecting cerebral hypoperfusion during carotid endarterectomy. We compared middle cerebral artery blood flow velocities with carotid artery stump pressures to evaluate the indications for common carotid artery cross-clamp shunting and the probable hemodynamic causes of cerebrovascular complications. METHODS Blood fl...

Internal Carotid Artery Occlusion Diagnosed by Doppler Ultrasound • Using a transcutaneous Doppler ultrasonic blood velocity detector, retrograde ophthalmic artery blood flow was demonstrated in four patients, all of whom had angiographically confirmed occluded internal carotid arteries. In three, compression of the facial artery obliterated the ophthalmic artery signal. In a fourth patient com...

PURPOSE To describe the technique and results of percutaneous puncture of the external carotid artery or one of its branches distal to a surgical arterial ligation. METHODS Forty-three patients underwent 64 embolization attempts by percutaneous arterial puncture distal to an external carotid artery ligation. The punctured arteries were the trunk of the external carotid artery in 31 patients, ...
