PURPOSE The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA). MATERIALS AND METHODS We retrospectively reviewed the medical records and image findings of all patients who were diagnosed...

1 1.05 and arched palate. Neither skin abnormalities nor hyperextensible joints were found. She was treated with aspirin at 250 mg daily. Three days later, she suddenly became comatose and was transferred to the neurological intensive care unit for respiratory assistance. Her Glasgow Coma Scale rated 6, she presented with spastic tetraparesis. Cerebral CT scan, Doppler sonography and cerebral M...

A 60-year-old man visited the outpatient clinic due to one month of recurrent exertional chest pain. Eleven years earlier he had undergone off-pump coronary artery bypass grafting using bilateral internal thoracic artery (ITA) Y-composite grafts based on the left ITA. Preoperative coronary angiography showed patent distal graft anastomoses and visualized the left ITA retrogradely. The arch aort...

Carotid artery stenosis (CAS) is one of the main causes stroke, as internal carotid (ICA) a major source cerebral blood supply. A common surgical intervention for CAS endarterectomy (CEA), which carries high risk stroke and mortality. CEA indicated 50% to 99% in symptomatic patients 60% asymptomatic patients. duplex ultrasound frequently used estimate peak systolic velocity (PSV), end diastolic...

A pathological examination was performed on normotensive rats (NTR) and spontaneously hypertensive rats (SHR) following bilateral common carotid artery ligation. After ligation, diffuse and extensive cerebral infarcts in the carotid artery territory occurred frequently in SHR, while NTR occasionally had well-circumscribed small infarcts. The posterior communicating arteries, which are the major...

BACKGROUND Brief antecedent periods of coronary artery occlusion improve subsequent vessel patency in damaged and stenotic coronary arteries via release of adenosine from ischemic/reperfused myocardium and resultant adenosine receptor stimulation. However, the site of receptor stimulation-circulating blood-borne elements (ie, platelets) versus vessel-wall components of the culprit artery-remain...
