background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

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. ...

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...

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...

A rare morphology of an aberrant innominate artery (IA) is reported here, together with additional arterial variation encountered in the respective specimen. The IA originated in the aortic arch on the left side of the trachea, coursed on that side of the trachea to reach the left thyroid lobe, turned in at a right angle to pass anterior to the trachea and immediately inferior and parallel to t...

Percutaneous transluminal angioplasty was used to treat stenotic lesions in 10 external carotid arteries in nine patients. Four representative cases are described. Nine arteries were successfully dilated. One attempt failed because the catheter could not be passed through the stenosis. Spasm of the distal external carotid artery due to guide wire-catheter manipulation was seen in six patients. ...

Aneurysms at non-branching sites in the supraclinoid internal carotid artery (ICA) can be classified as "blood blister-like aneurysms" (BBAs), which have blood blister-like configurations and fragile walls. While surgical treatment for the BBA in the acute stage is recommended, the optimal surgical procedure remains controversial. In the study reported here, we describe the case of a 37-year-ol...

the carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. the aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in makouei sheep. fourteen heads of sheep from both sexes were collected from urmia public slaughter-house. the exact situation and nerve supply of ...

background sphenoid sinus is surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...

BACKGROUND In horses, the extracranial and intracranial pathway of the internal carotid artery has been described. The extracranial pathway of the internal carotid artery begins at the carotid termination and runs on the dorsal surface of the medial compartment of the guttural pouch. Thereafter the internal carotid artery passes through the foramen lacerum to continue intracranially, forming pa...
