Occlusion of the common carotid artery (CCA) is rare. CCA occlusion (CCAO) can present as drowsiness and right hemiplegia related to emboli after total arch replacement. Although we selected a follow-up at first because color duplex sonography showed retrograde flow from the left external carotid artery to the internal carotid artery, this patient had epilepsy and single-photon emission compute...

Purpose: We performed the present study to determine whether the site of cardioembolic occlusion in the carotid axis could be identified by end-diastolic velocity measurements of the common carotid arteries. Summary of Report: Using duplex carotid ultrasonography, we measured the flow velocity in the common carotid arteries and calculated the side-to-side ratios of the end-diastolic velocity (E...

Objective(s): The main goal of the current research was to examine the effects of Berberine (BBR) on apoptotic signaling and hippocampal oxidative stress induced by common carotid artery occlusion. Materials and Methods: Chronic cerebral hypoperfusion (CCH) model was created by occluding the two common carotid arteries (two-vessel occlusion [2VO]) permanently. BBR (50 and 100 mg/kg/daily) was i...

701 PREVIOUS STUDIES FROM THIS LABORATORY HAVE BROUGHT FORTH EVIDENCE SUGGESTING THAT IMBALANCES BETWEEN CAROTID AND VERTEBRAL blood flow and temperature underlie the increase in preoptichypothalamic temperature during rapid eye movement (REM) sleep in several mammalian species.1 Particularly relevant to the mechanism of such a temperature increase are the effects on preoptic-hypothalamic tempe...

Distal embolization resulting from carotid angioplasty and stenting (CAS) occurs mainly in the cerebral hemisphere. We report a case of ophthalmic artery occlusion after carotid revascularization. A 75-year old man received emergency CAS for cervical internal carotid artery occlusion. Two months later, the patient was readmitted for decreased visual acuity. We found ophthalmic artery occlusion ...

PURPOSE We performed the present study to determine whether the site of cardioembolic occlusion in the carotid axis could be identified by end-diastolic velocity measurements of the common carotid arteries. SUMMARY OF REPORT Using duplex carotid ultrasonography, we measured the flow velocity in the common carotid arteries and calculated the side-to-side ratios of the end-diastolic velocity (E...

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 ...

BACKGROUND AND PURPOSE Leptomeningeal collateral growth is a key factor that defines the severity of ischemic stroke. Patients with stroke generally have vascular risk factors, such as diabetes mellitus; however, consensus is lacking on how diabetes mellitus affects leptomeningeal arteriogenesis. We investigate the influence of diabetes mellitus on the leptomeningeal arteriogenesis. METHODS W...

Introduction: Subclavian steal syndrome refers to the reversal of vertebral blood flow in the setting of proximal subclavian or innominate artery severe stenosis or occlusion resulting in the symptoms of vertebrobasilar insufficiency related to exercise of the upper extremities. It is more common on the left side. Case report: We reported a case of subclavian steal syndrome on the right side in...

Doppler ultrasonic assessment of extracranial carotid occlusive disease has been modified to decrease the incidence of false positive and negative diagnoses. The technique, which assessed directional flow in the frontal artery and the influence of sequential compression of each temporal, infraorbital, facial and common carotid artery, was performed on 152 vessels visualized by contrast arteriog...
