Common Carotid Artery Agenesis: Duplex Ultrasonographic Findings
BACKGROUND Agenesis of the common carotid artery (CCA) resulting in separation of the origin of the external carotid artery (ECA) and internal carotid artery (ICA) from the aortic arch is rare. Fewer than 25 cases have been reported, and correlative ultrasound data were available for only 1 of them. CASE REPORT A 52-year-old woman visited the hospital with a 3-day history of vertigo and heada...
متن کاملReport of a Variation of the Right Common Carotid Artery
Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...
متن کاملMechanical properties of the common carotid artery in Williams syndrome.
OBJECTIVE To determine whether arterial wall hypertrophy in elastic arteries was associated with alteration in their mechanical properties in young patients with Williams syndrome. METHODS Arterial pressure and intima-media thickness, cross sectional compliance, distensibility, circumferential wall stress, and incremental elastic modulus of the common carotid artery were measured non-invasive...
متن کاملVariations in the anatomical relationship between the common carotid artery and the internal jugular vein: an ultrasonographic study.
INTRODUCTION The internal jugular vein locates anterior or anterolateral to the common carotid artery in two-thirds of the subjects studied by ultrasound when the head is in a rotated position. AIM To identify variables associated with the anterior location of the internal jugular vein. METHODS Ultrasound examinations were performed with the patients in the supine position, with the head ro...
متن کاملNoninvasive Angiography for the Diagnosis of Carotid Artery Disease Using Doppler Ultrasound (Carotid Artery Doppler)
To detect stenosis in the carotid artery with a bidirectional continuous-wave Doppler ultrasound device, the following noninvasive procedure, applied on 800 patients and compared with 249 angiograms of 186 patients, has proved to be about 90% reliable. Measurements of flow signals were taken over the terminal branches of the ophthalmic artery (supratrochlear and supraorbital arteries) and avera...
