mycotic aneurysm could be divided into three types according to their etiology: septic-embolic, cryptogenic and traumatic type. during the period from 1972 to 1974 two cases of mycotic aneurysms have been seen at the ohio valley medical center - one following a sub acute bacterial endocarditic and another one was two years following surgery for aortofemoral bypass graft. the clinical course of ...

Introduction: In this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. A window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. Material and Methods: The program was...

In this paper, radiated sound from low Mach number turbulent boundary layers is studied using Lighthill’s analogy. The focus is on investigating the behavior of wall pressure fluctuations on a flexible wall boundary. Comparisons are made between the results from rigid and flexible walls. At low frequencies, the flexible wall results have shown much higher levels of power spectra. At high freque...

PURPOSE We aimed to visualize the retinal arterial wall thickness, assisted by noninvasive adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS The arterial wall thickness was measured and compared between one normal subject and one patient suffering from malignant hypertensive retinopathy. RESULTS Increased arterial wall thickness was revealed with a newly developed AO-SLO syste...

BACKGROUND AND PURPOSE The aim of the study was to determine the effects of thromboembolism and mechanical thrombectomy on the vessel wall magnetic resonance imaging (VW-MRI) appearance of the intracranial arterial wall. METHODS This was a cross-sectional study of consecutive patients with acute intracranial arterial occlusion who underwent high-resolution contrast-enhanced VW-MRI within days...

BACKGROUND AND PURPOSE Prospective differentiation between reversible cerebral vasoconstriction syndrome and central nervous system vasculitis can be challenging. We hypothesized that high-resolution vessel wall MRI would demonstrate arterial wall enhancement in central nervous system vasculitis but not in reversible cerebral vasoconstriction syndrome. METHODS We identified all patients with ...

Arterial stiffness has independent predictive value for cardiovascular events. We review data concerning the heritability of arterial stiffness, and propose an integrated view of the structural and genetic determinants of arterial stiffness, based on a candidate gene approach and recent studies on gene expression profile. Arterial stiffness seems to have a genetic component, which is largely in...

We have performed numerical simulations to examine saccular cerebral aneurysm formation at the outer curve of a bent artery. A U-shaped arterial geometry with torsion, which was modeled on part of the human internal carotid artery, has been employed. A new numerical model was proposed to take into account proliferation as well as degradation of the arterial wall. Proliferation of the arterial w...
