In 38 patients who underwent cerebrovascular evaluation followed by angiography the Doppler ultrasound scanning technique was found to be an excellent screening procedure for detecting marked stenosis (>50%) or occlusion of the internal carotid artery (93% correlation). It is noninvasive, easily reproducible and can be performed by a qualified technician. The major problems are: the inability t...

In 38 patients who underwent cerebrovascular evaluation followed by angiography the Doppler ultrasound scanning technique was found to be an excellent screening procedure for detecting marked stenosis (greater than 50%) or occlusion of the internal carotid artery (93% correlation). It is noninvasive, easily reproducible and can be performed by a qualified technician. The major problems are: the...

Carotid Arterial Supply of the Feline Brain • A study of the supply to the feline brain by the carotid-middle cerebral arteries was conducted using in vivo transcardiac injection with a mixture of micropaque and carbon black. Modifications in the filling pattern of the arterial vessels were visualized following short-term occlusion of a middle cerebral artery. A modified surgical method to indu...

Although inflammatory periodontal disease has been proven to be related to carotid intima media thickness, it has been recently suggested that even an alteration of carotid hemodynamics might contribute to atherosclerosis in patients with periodontal disease. A 52-year-old female patient was referred to periodontology department due to painful alveolar mucosa. On the basis of dental history, we...

AANA Journal/June 2007/Vol. 75, No. 3 193 Carotid endarterectomy is a procedure used to treat severe atherosclerotic occlusive disease involving the internal carotid arteries, most often at the common carotid artery bifurcation. The operation is performed by opening the common carotid arteries and the proximal internal carotid arteries in the neck, removing plaques from the inside of the arteri...

A 66-year-old man suffering from neurologic symptoms caused by acute embolic total occlusion of the left middle cerebral artery was treated successfully with balloon angioplasty, and an ipsilateral carotid stenosis subsequently was dilated with stenting. The patient's clinical outcome 30 days later was favorable. This therapeutic option may prove to be a useful means of treating a patient with ...

We studied the role of cardiopulmonary vagal afferents in the cardiovascular responses to coronary artery occlusion in conscious dogs with intact carotid sinuses and following functional denervation of the arterial baroreceptors. The contributions of vagal afferents were determined by cold blocking the vagi. In dogs with intact carotid sinuses, coronary artery occlusion produced small decreases...
