conclusion results reinforced the pivotal role of vascular geometry, with respect to hemodynamics, together with the importance of performing patient-specific cfd analyses, through which the effect of different blood flow conditions on the aneurysm hemodynamics could be evaluated. objectives this study aimed to investigate the effects of variations in heart rate and internal carotid artery (ica...

A 65-year-old man developed subacute horizontal diplopia due to left abducens nerve (AN) palsy and excessive eye tearing. Brain MRI revealed a hyperintense T2 lesion with an elongated course within the carotid canal, presenting homogenous contrast enhancement (figure 1). The imaging findings were characteristic for internal artery sympathetic plexus (ICSP) schwannoma compressing AN. Subsequent ...

Two main vascular routes supply the brain, internal carotid arteries (ICAs) and vertebral arteries. The external artery (ECA) mainly supplies skin, muscle, skull; thus, neurointerventionalists should be aware of ECA‐ICA, ECA‐vertebral artery, extracranial–intracranial anastomoses. These anastomoses are not newly formed but that remnants developmental processes. During development, ICA has with ...

We developed new methods for isolating in situ baroreceptor regions of carotid sinus and aortic depressor nerves in halothane-anesthetized rats. After ligation of the root of the external carotid artery, the internal carotid and pterygopalatine arteries were embolized with two ball bearings of 0.8 mm in diameter. Bilateral carotid sinus pressures were changed between 60 and 180 mmHg in 20-mmHg ...

there are epidemiologic evidences suggested an increased carotid intima/media thickness (imt) as a predictor of cardiovascular disease events. the purpose of this study was to determine the differences of imt means in patients with positive and negative coronary angiographic findings. background: we conducted a case control study on patients with typical stable angina pectoris. the case group i...

NEUROGENIC hypertension can be produced in dogs by denervation of the carotid sinus and disruption of the vago-aortic nerves. This procedure usually results in severe hypertension, the hemodynamics of which were studied by several investigators.' Chronic disruption of the carotid sinus nerves alone, was thought not to effect the blood pressure. This Avas attributed to sufficient buffer action o...
