purpose: to compare ipsilateral and contralateral carotid wall thickness in patients with acute unilateral non-arteritic anterior ischemic optic neuropathy (naion). methods: this prospective case series included 17 (10 male and 7 female) patients with unilateral naion of less than 8 weeks' duration who underwent b-mode ultrasonography to measure intima-media thickness (imt) in the common c...

Changes of regional cortical blood flow (rCBF) was monitored by the heat clearance method during the operation of cervical carotid ligation combined with superficial temporal artery and middle cerebral artery anastomosis for the treatment of inaccessible aneurysms of the internal carotid artery in eight patients. There were three types of rCBF responses upon closure of the internal carotid arte...

AIM In surgeries involving clamping, opening and repairing the carotid artery such as carotid endarterectomy (CEA) and proximal anastomosis at radial artery (RA) grafting, back-bleeding, often due to insufficient occlusion of the ascending pharyngeal artery (APA), must be avoided. In 96% of cases the APA originates at the dorsal side of the external carotid artery, while in 2% each it arises at...

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. ...

The first successful reconstruction of a stenotic internal carotid artery was performed in 1951 by Carrera et al.1 The first successful carotid reconstruction was performed by Carrera et al. in 1951 in a male patient suffering from stroke2. During this procedure, they cut out the stenosed area of the proximal internal carotid artery and made an end-to-end anastomosis using the transected proxim...

Carotid stenosis is a major cause of stroke and timely intervention with stenting manipulation can significantly reduce the risk of secondary stroke. The impact of stenting procedures on patient functional capabilities has not yet been explored. The primary aim of this study was to examine associations between periprocedural carotid sonography parameters and post-treatment functional capabiliti...

Carotid artery stenosis is relatively common and is a significant cause of ischemic stroke, but carotid revascularization can reduce the risk of ischemic stroke in patients with significant symptomatic stenosis. Carotid endarterectomy has been and remains the gold standard treatment to reduce the risk of carotid artery stenosis. Carotid artery stenting (CAS) (or carotid artery stent implantatio...

The left superior laryngeal artery was observed arising from the external carotid artery instead of the superior thyroid artery in the cadaver of an approximately 70 year-old Asian man. In addition, on the same side, the superior thyroid artery arose from the common carotid artery 2 cm before the bifurcation instead of its usual origin from the external carotid artery. From the external carotid...

background diabetes mellitus is a widespread disease. its vascular complications can be characterized by arteriosclerosis formation in carotid arteries. due to its delayed diagnosis resulting in more complications in iran, it seems that screening diabetic patients is mandatory. objectives the aim of this study was to compare the intima-media thickness (imt) of carotid artery in diabetic and non...

BACKGROUND Renovascular disease is the most frequently encountered secondary cause of hypertension and is one of the few potentially reversible causes of chronic renal failure. These patients are at increased risk of having cerebrovascular events following operative management for atheromatous renal-artery stenosis. We studied the prevalence of carotid-artery disease in patients with atheromato...
