Usefulness of Doppler Sonography of Ophthalmic Artery for Occlusive Internal Carotid Artery Diseases

Doppler ophthalmic blood pressure measurement in the hemodynamic evaluation of occlusive carotid artery disease.

In 102 patients with angiographically proven occlusive carotid artery disease of 60-100% diameter reduction, Doppler ophthalmic artery pressure and blood flow direction were recorded by the recently developed ophthalmomanometry-Doppler technique. Among these 102 patients, 50 presented with complete carotid artery occlusions and 52 with carotid artery diameter stenoses of greater than or equal t...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Japanese Registry of Neuroendovascular Therapy: Extracranial Steno-occlusive Diseases except for Internal Carotid Artery Stenosis

Although utilization of endovascular treatment of extracranial steno-occlusive lesions except for internal carotid artery stenosis continues to increase, there is no consensus regarding the natural course and standard treatment of these lesions. The aim of this study was to characterize the utility of endovascular treatment for extracranial steno-occlusive lesions except for internal carotid ar...

Carotid artery occlusive disease

• Stroke is the third most common cause of death following cardiovascular disease and cancer and is the most common cause of neurological disability. 70-85% of stroke is ischemic and 20-30% is due to atherosclerosis of CCA. • Pathogenesis: endothelial injury or dysfunction-platelet aggregation and inward migration of mononuclear cells and lymphocytes-release of growth factors-migration and prol...

Diagnosis of internal carotid artery stenosis greater than 70% with power Doppler duplex sonography.

BACKGROUND AND PURPOSE Duplex sonography is an effective tool for evaluating internal carotid artery (ICA) stenosis, and power Doppler imaging has improved its value in this regard. Our goal was to elucidate which parameters, such as linear stenosis, area stenosis, and peak systolic velocity (PSV), are the most reliable predictors of ICA stenosis greater than 70% using the method proposed by th...
