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...

BACKGROUND Takayasu arteritis is a rare, chronic large vessel vasculitis involving the aorta and its primary branches. As the disease progresses, the active inflammation of large vessels leads to dilation, narrowing and occlusion of the arteries. Arterial dissection is due to separation of the layers of the arterial wall resulting in a false lumen, where blood seeps into the vessel wall. Neurol...

Blunt traumatic occlusion or stenosis of the internal carotid artery is a rare complication of whiplash injury and may not be recognized until the onset of neurological symptoms. The clinical course can vary considerably, with regard to both the symptoms and the interval between injury and manifestation. A dissecting aneurysm and intimal tear are usually observed after blunt internal carotid ar...

A 3-year-old child was examined because of otorrhagia. CT scans showed an unusual vessel, confirmed by angiography, related to a persistent pharyngohyostapedial artery. This embryonic persistent artery associated with the normal internal carotid artery would explain the "duplication" aspect of the internal carotid artery.

Objective: Most large-vessel occlusions (LVOs) amenable to acute recanalization occur in the internal carotid or middle cerebral artery. However, few LVOs with a multivessel disease can be difficult treat. This study aimed determine outcomes of mechanical thrombectomy patients both anterior and artery occlusions.

In this study, Doppler signals recorded from internal carotid artery of 45 subjects were processed by PC-computer using classical (fast Fourier transform) and model-based (autoregressive, moving average, autoregressive moving average (ARMA) methods) methods. Power spectral density estimates of internal carotid arterial Doppler signals were obtained using these spectral analysis methods. The var...

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...

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...

Spontaneous dissections of the extracranial internal carotid artery are diagnosed more frequently as their clinical and angiographic features are more widely recognized. Familial occurrence of spontaneous dissection of the internal carotid artery has not been previously reported. We describe the occurrence of this entity in a mother and daughter and also in a father and son. The familial occurr...
