... Abstract Anterior cerebral artery (ACA) territory strokes account for 0.5-3% of all ischemic strokes. The etiological mechanisms of ACA territory strokes vary by race; ACA dissection is a frequent cause in Japan. The most prevalent symptom of such strokes is contralateral hemiparesis...

... and the location of the anterior ethmoidal artery (AEA). The frontal recess cells and the AEAs were retrospectively evaluated in CT scans of the nasal and paranasal sinuses for 89 patients. The prevalence of agger nasi cells was 90.7%. The frequency of frontal cell types 1, 2, 3 and 4 was 28.8, 0.6, 2.6 and 0...

... Abstract The optical coherence tomography angiography (OCTA) microvascular features of branch and central retinal artery occlusion are described and correlated with fluorescein angiographic and clinical findings. There may be differences in the distribution of reduced vascular perfusion/flow...

... Abstract For many years clopidogrel was the ‘gold standard’ ADP receptor antagonist in patients with coronary artery disease in combination with acetylsalicylic acid, i.e. in elective/stable patients after coronary stent implantation and in patients with acute coronary syndromes with/without...

... animals was required. To this end, changes in isometric tension of isolated rings of the common digital artery of the fallow deer, killed for the venison market, in response to selected NO-NSAIDs and their parent NSAIDs (notably aspirin, ibuprofen, diclofenac and flurbiprofen) were measured...

... Abstract Retinal artery occlusions (RAO) are characterized by the sudden obstruction of the arterial blood flow in the retinal circulation with consequent ischemic damage to the retina. RAO can be subdivided into several forms, including central retinal artery occlusion (CRAO) and Branch...

... Abstract Occlusions of the central retinal artery or of its branches are mostly due to an embolism of carotid or cardiac origin. In younger people, inflammatory diseases or thrombophilia may also be involved in rare cases. So far, no treatment has proved effective in restoring visual acuity...

... Abstract The superficial middle cerebral artery (MCA) territory includes the greater part of the lateral surface of the cerebral hemisphere. It is the most frequent infarct in MCA ischemic cerebrovascular pathology. It is divided into 12 areas supplied by 12 different arteries referred...

... Abstract The anterior choroidal artery (AChA) originates from the posterior wall of the internal carotid distal to the posterior communicating artery and proximal to the intracerebral carotid bifurcation. This thin artery is rarely the cause of aneurysm and only accounts for 2-5% of all...

... Abstract Infarctions in the territory of the posterior cerebral artery (PCA) occur in about 5-10% of all ischemic strokes. The PCA can be divided into ‘deep' (P1 and P2 segments) and ‘superficial' (P3 and P4) segments. Occlusion of paramedian perforating arteries arising from P1 causes rostral...

... Abstract Large middle cerebral artery (MCA) and panhemispheric stroke represent a minority of cerebral ischemic events, yet they are responsible for a disproportionate share of morbidity and mortality. Malignant infarction with formation of cerebral edema is a common cause for secondary...

... Abstract The strongest independent risk factors for coronary artery disease (CAD) are increasing age and male gender. Whilst a wide variation in CAD mortality exists between countries, a male to female ratio of approximately 2:1 is consistently observed. These observations have led...

... Abstract To mimic cerebral ischemia leading to stroke in man, many animal models have beenmade which occlude brain arteries, transiently or permanently. These models are aimed atstudying the morphological changes and the pathophysiology of stroke, and at screening andtesting new neuroprotective...

... Abstract Ultrasound allows the reliable exclusion of spontaneous dissection of the cervical internalcarotid artery (sICAD) in patients with carotid territory ischemia. The possibility offalsely positive ultrasound findings indicates that cervical magnetic resonance imaging(MRI) and angiography...

... Abstract We developed a canine model of arterial dissection and serially observed morphological changes angiographically and histopathologically to clarify the causes and mechanisms resulting in dissecting aneurysm formation or arterial occlusion. Intimal defects of various sizes and shapes...
