Hemodynamic characteristics of hyperplastic remodeling lesions in cerebral aneurysms
BACKGROUND & PURPOSE Hyperplastic remodeling (HR) lesions are sometimes found on cerebral aneurysm walls. Atherosclerosis is the results of HR, which may cause an adverse effect on surgical treatment for cerebral aneurysms. Previous studies have demonstrated that atherosclerotic changes had a correlation with certain hemodynamic characteristics. Therefore, we investigated local hemodynamic char...
متن کاملHemodynamic Effects of Cerebral Arteriovenous Aneurysms.
PERIPHERAL arteriovenous aneurysms cause chronic increases in cardiac work load and heart failure may result. These phenomena have been widely observed in patients1 4 and in experimental animals.0 However, there still appears to be doubt concerning the cardiovascular effects of such aneurysms when they are located above the heart.8-12 Hemodynamic measurements in eight patients with cerebral art...
متن کاملReactive Hyperplastic Lesions of the Oral Cavity
Introduction: Peripheral reactive lesions of soft tissue are common oral lesions that dentists face during routine examinations. Diagnosis and development of a treatment plan is difficult if dentists are not aware of the prevalence and clinical symptoms of these lesions. The frequency of these lesions differs across various populations. The aim of this study was to determine the frequency and d...
متن کاملHemodynamic Characteristics of Cerebral Arteriovenous Malformation Feeder Vessels With and Without Aneurysms.
BACKGROUND AND PURPOSE The pathogenesis of aneurysms associated with cerebral arteriovenous malformation (AVM) feeder vessels is poorly understood. We sought to determine the hemodynamic characteristics of AVM feeder vessels with and without aneurysms. METHODS Patients with AVMs associated with feeder aneurysms who had flow, vessel diameter, and wall shear stress measured before treatment usi...
متن کاملHemodynamic characteristics at the rupture site of cerebral aneurysms: a case study.
BACKGROUND AND IMPORTANCE Hemodynamics play an important role in the mechanisms of aneurysm formation, growth, and rupture. However, little is known about the hemodynamics of rupture sites. CLINICAL PRESENTATION We incidentally acquired 3-dimensional images before and at the moment of rebleeding of a cerebral aneurysm in a patient. Comparison of these 2 images enabled precise identification o...
