A 2-year-old girl presented with cutaneous facial, palpebral, back, perianal, and perineal hemangiomas and a subcutaneous neck and parotid voluminous hemangioma, associated with several extracranial vascular abnormalities, such as the absence of the ipsilateral internal carotid artery and hypoplasia of the common carotid arteries. Both vertebral arteries showed an embryonic appearance, without ...

Several recent results obtained in hypertensive animals and subjects under in vivo isobaric conditions do not confirm the classic view of stiffer arteries in hypertensive subjects. We compared the mechanical behavior of in situ isolated common carotid arteries from normotensive Wistar-Kyoto rats (WKY) and age-matched spontaneously hypertensive rats (SHR) under both static and dynamic conditions...

BACKGROUND In-stent restenosis due to intimal hyperplasia is an important clinical problem. Animal models of stent injury are limited by inconsistent arterial responses to stenting, and less intimal hyperplasia than diseased human vessels. To address these issues, we aimed to compare the degree of intimal hyperplasia in stented rabbit jugular-carotid interposition grafts (vein grafts) versus st...

PURPOSE To document a case of central retinal artery occlusion after chiropractic treatment. METHODS An 87-year-old man suffered a central retinal artery occlusion immediately after chiropractic neck manipulation. RESULTS A magnetic resonance angiogram showed an atherosclerotic plaque in the ipsilateral carotid artery, which probably shed emboli during cervical joint mobilization. CONCLUS...

BACKGROUND AND PURPOSE We tested the hypothesis that transcranial Doppler embolic signal (ES) detection identifies an increased risk of ipsilateral carotid stroke or transient ischemic attack (TIA) in subjects with asymptomatic severe carotid stenosis. METHODS Subjects with duplex-determined 60% to 99% carotid stenosis, without other apparent cerebroembolic sources, underwent 6-monthly neurol...

introduction: the present study evaluated morphological changes of ca1 hippocampal neurons following transient bilateral common carotid and permanent left middle cerebral arteries occlusion, also the neuroprotective effects of aspirin i.p injection was inducing assessed after ischemia in male rat. material and methods: in this experiment, 4 groups of animals were used including; control, sham, ...

OBJECTIVE The purpose of our study was to assess prevalence of carotid intraplaque hemorrhage (IPH) and associations between territorial acute infarction and IPH on magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) in patients with acute neurologic symptoms. METHODS 83 patients with suspected acute neurologic symptoms were evaluated with both brain diffusion weighted imagin...

INTRODUCTION Only a few studies have investigated the structural and functional characteristics of carotid arteries bilaterally. Furthermore, there is controversy as to whether inflammation in paired vascular beds is a local or systemic phenomenon. We aimed to examine, in patients with coronary artery disease, whether intra-subject left and right carotid arteries have similar inflammatory statu...

plastic adhesives, normal butyl cyanoacrylate monomer, isobutyl cyanoacrylate monomer and methyl 2 _ cyaooacrylate monomer, have been utilized in a comparative study with 5-{) silk suture in the repair of transected carotid arteries. follow _ up arteriog rams indicate isobutyl cyanoacrylate monomer and normal butyl cyanoacrylate monomer as having the most impressive rerults with only two thromb...

PURPOSE To assess the effectiveness of self-expanding, cobalt-alloy stents in the treatment of aneurysms in a canine model and to observe the pattern of blood flow and formation of fibrotic scar tissue. METHODS Porous metallic stents were endovascularly placed across the necks of experimentally created side aneurysms in the carotid arteries of three dogs; aneurysms were also created in the op...
