the carotid sinus is a modification in the vascular wall near the bifurcation each common carotid artery and acts as baroreceptor. in this study 16 adult and apparently healthy buffaloes ie. 8 male and 8 female used for the as well as macroscopic orientation microscopic study of the carotid sinus. our study revealed that in the buffalo, carotid sinus is a dilatation in common carotid artery at ...

In vitro studies have demonstrated that geometry of the carotid bifurcation predicts blood flow alterations associated with atherosclerotic plaque formation. We investigated intraindividual asymmetry of carotid atherosclerosis by measuring geometric aspects of the carotid bifurcation. We measured diameter stenosis, the internal carotid artery/common carotid artery area ratio, and the angle of t...

normal 0 false false false en-us x-none ar-sa carotid body tumor (cbt) is paraganglioma and mainly found in the carotid bifurcation. the manifestations of the tumor are variable; in most cases, it presents as a non-symptomatic slow-growing mass, rarely compression of carotid body induces bradycardia and hypotension and repeated syncope, prolonged syncope can cause convulsion. convulsive syncope...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

OBJECTIVE To determine site specific carotid intima-media thickness: common-carotid artery and carotid bifurcation in hypercholesterolemia patients as a marker for atherosclerosis. METHODS Fifty patients with hypercholesterolemia and twenty controls were selected after getting informed consent regarding the investigation of carotid- intima media thickness by B-mode ultrasound. All the patient...

The results for blood flow in the carotid artery bifurcation on the basis of numerical simulation of Navier-Stokes equations are presented in this study. Four cases of carotid bifurcation are considered: common carotid artery (CCA) bifurcation without stenoses and cases with one, two and three stenoses are also presented. The results are obtained by performing numerical simulations considering ...

Surgical anatomy of carotid bifurcation is of unique importance for numerous medical specialties. Despite extensive research, many aspects such as precise height of carotid bifurcation, micrometric values of carotid arteries and their branches as their diameter, length, and degree of tortuosity, and variations of proximal external carotid artery branches are undetermined. Furthermore carotid bi...

Aneurysms of the supra-aortic trunks are rare conditions that can cause peripheral neurological conditions or embolization resulting in stroke. The upper airways can even be affected and rupture is potentially fatal. We present a case of a patient with an aneurysm of the carotid bifurcation who was treated conventionally with reconstruction of the carotid bifurcation using a venous patch. Surgi...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

The common carotid artery usually bifurcates into the internal and external carotid arteries at the level of C3-C4. Injury to common carotid artery during neck dissection is encountered rarly. Knowing the anatomical variation of common carotid like low lying bifurcation would prevent inadvertent injury especially by budding head-neck surgeons. We report a case of 46-yearold male undergoing surg...
