BACKGROUND AND PURPOSE Prevalence of carotid artery stenosis in patients with coronary artery disease (CAD) is unknown in Japanese population. METHODS The study populations consisted of 632 consecutive patients who underwent coronary angiography because of suspicion of CAD. All patients underwent carotid ultrasonography to screen carotid artery stenosis before coronary angiography. We defined...

The purpose of this study was to evaluate the feasibility and accuracy of combined coronary and perfusion cardiovascular magnetic resonance (CMR) in the assessment of coronary artery stenosis. Thirty-five consecutive patients (27 men, eight women, age range 34-81 years), undergoing cardiac catheterization, were assessed with 3D coronary CMR and rest-stress perfusion CMR. Significant coronary st...

Abstract We report a case of 4-year-old boy who presented with moyamoya disease associated midaortic syndrome. He had been treated for severe persistent hypertension until he suffered multiple episodes seizure and cerebral ischemic attack. Cerebral angiography showed bilateral terminal internal carotid artery stenosis. Angiographic survey stenosis abdominal aorta proximal renal arteries. This i...

BACKGROUND AND PURPOSE The risk of ischemic stroke in patients with asymptomatic vertebral artery stenosis is unknown. We examined the incidence of posterior circulation ischemic stroke in patients with asymptomatic stenosis of the vertebral artery origin (VAo). METHODS We studied a hospital-based cohort of 3717 patients (median age, 60 years; interquartile range, 52 to 68 years) with atheros...

INTRODUCTION Branches from the cervical portion of the internal carotid artery are rare. In most cases, atherosclerotic stenosis is found at the bifurcation of the internal and external carotid arteries. However, when associated with atherosclerotic carotid artery disease, the origin of the rare branches arising from the internal carotid artery can be another site of stenosis. This report descr...

Introduction Approximately one-quarter of ischaemic strokes involve the posterior or vertebrobasilar circulation. 1,2 Stenosis of the vertebral artery can occur in either its extra-or intracranial portions, and may account for up to 20% of posterior circulation ischaemic strokes. 3–6 Stenotic lesions, particularly at the origin of the vertebral artery, are not uncommon. In an angiographic study...

Renovascular disease includes renal artery stenosis, renovascular hypertension, and azotemic renovascular disease (ischemic nephropathy). It is important to distinguish between renovascular hypertension and renal artery stenosis. Stenosis of the renal artery is common in nonhypertensive elderly persons and is an associated but noncausative finding in a number of hypertensive patients. Renovascu...

The incidence of stroke would be decreased if the vertebral artery stenosis could be diagnosed early and therapy effectively. Presently, the Digital Subtraction Angiography (DSA) is a new computer-assisted radiographic procedure to diagnose the vertebral artery stenosis, and can provide clinical information for therapy. In this paper, the hemodynamic characteristics of the vertebral artery sten...
