We report a hybrid surgery including endovascular aneurysm repair and debranching procedures to treat a patient with a complex right subclavian artery aneurysm. The patient was a 70-year-old woman who presented with dry cough and hoarseness. The aneurysm was characterized by the absence of a proximal neck, and involvement of the origin of the right vertebral artery. She underwent carotid-verteb...

OBJECTIVE To assess whether the intima-media thickness of the common carotid artery of patients with coronary artery disease is greater than that of individuals without that disease. METHODS Case-control prospective study of prevalence assessing the thickness of the intima and media layers of 29 patients with coronary artery disease and 29 individuals without that disease by using ultrasonogr...

Adequate intracranial collateral circulation reduces risk of stroke in carotid artery surgery. To evaluate their relative accuracies in assessing intracranial collateral blood flow, we prospectively compared transcranial Doppler and continuous-wave Doppler of the cervical carotid arteries combined with compression of the common carotid artery in 28 consecutive patients before carotid endarterec...

Duplex ultrasound is currently used both for screening and for preoperative assessment of the carotid arteries and has completely replaced carotid angiography for the latter purpose in many institutions. The study aimed to identify resistivity index abnormalities in the common carotid arteries in patients with occluded or severely stenosed internal carotid arteries. Sixteen patients with severe...

beta-adrenergic receptors were measured in cerebral microvessels of gerbils and rats after ligature of the right or left common carotid artery. The results indicate a decrease in the number of beta-adrenergic receptors in brain microvessels of both ipsilateral and contralateral hemispheres. This event may reflect altered patterns of the neuronal regulation of brain microvasculature and may be r...

Bovine aortic arch refers to the most common variant of aortic arch branching in humans. This configuration can be found in approximately 27% of the population and can be further divided into 2 subtypes. In the less usual subtype (7%, Figure 1 – panel A), the innominate artery (usually 1-2.5 cm long) trifurcates into the left common carotid artery, the right common carotid artery and the right ...

Aneurysms of any part of the extracranial carotid artery are uncommon lesions [1-6], and those involving just the common carotid segment may appropriately be considered rare. Although fusiform enlargement of the mediastinal segment of the left common carotid artery can occur in atherosclerotic disease and in association with syphilitic and other forms of aortitis, a saccular form of aneurysm in...

The aim of this study was to identify the main factor affecting compliance and intima-media thickness of the elastic common carotid artery in continuous ambulatory peritoneal dialysis patients. Increased intima-media thickness and decreased arterial compliance are associated with elevated risk of cardiovascular disease. This study included 20 patients and 20 age- and sex- matched healthy contro...
