Abstract Background and Aims The management of complications arteriovenous fistula (AVF) for hemodialysis, principally stenosis, remains a major challenge clinicians with substantial impact on health resources. Stenosis not infrequently preludes to thrombotic events the loss AVF functionality. A frequent monitoring physical examination is at basis an appropriate clinical care. It includes regul...

We present a patients with persistent position-dependent productive cough and intermittent fever. He was first examined at 38 yrs of age. Chest X-ray showed a severe thoracic lordoscoliosis and an atelectasis of the right lower lobe. Bronchography revealed a total stenosis of the right lower lobe bronchus. Five years later had increased symptoms. Spirometry showed total lung capacity (TLC) 3.8 ...

Intracranial atherosclerotic stenosis (ICAS) is a risk factor for ischemic stroke, and the primary aim of management is stroke prevention. The natural history of ICAS is influenced by symptomatic versus asymptomatic status, with symptomatic ICAS having a high recurrent stroke risk. The risk of stroke in symptomatic ICAS is dependent on many factors which will be reviewed in this chapter, includ...

A computational study of the blood flow in a stenosed microvessel is presented using coupled discrete ghost-cell and continuous-forcing immersed boundary methods. This focuses on studying platelet behaviors near stenosis with deformable red cells (RBCs). The influence varying hematocrit, area blockage, shape, driving force characteristics, RBCs, particle considered. Distinct characteristics are...

Vascular stenosis mainly on the basis of arteriosclerotic disease represents one of the major problems in cardiovascular disease. Vascular stenosis contributes significantly to the clinical consequences of arteriosclerotic disease being the leading cause of death in western countries. The etiology of vascular disease is very complex and many factors have been implicated such as abnormalities of...

A 61 year old man presented with mitral regurgitation and glomerulonephritis caused by suspected infective endocarditis. His glomerulonephritis remitted on immunosuppression but mitral valve replacement with a Carpentier-Edwards porcine xenograft later proved necessary. The patient became dialysis dependent and cadaveric renal allografting was complicated by delayed graft function and refractor...

introduction pulmonary vein stenosis includes narrowing of one or more pulmonary veins that may have congenital or acquired causes. congenital pulmonary vein stenosis is a rare condition and also a rare cause for pulmonary hypertension. since identifying the etiology of pulmonary hypertension plays a crucial role in medical and surgical planning, we decided to introduce a rare case of pulmonary...

AIMS To investigate collagen remodelling in the interstitium of the heart in patients with diabetes. METHODS Immunohistochemical study of the biopsied myocardium using type specific anticollagen antibodies (I, III, IV, V, VI) was performed in 12 patients with non-insulin dependent diabetes mellitus and six non-diabetic patients. There was no history of hypertension or coronary artery stenosis...

A computational study is presented on the flow of deformable red blood cells in stenosed microvessels. It is observed that the Fahraeus-Lindqvist effect is significantly enhanced due to the presence of a stenosis. The apparent viscosity of blood is observed to increase by several folds when compared to non-stenosed vessels. An asymmetric distribution of the red blood cells, caused by geometric ...

cutis laxa is rare and hetrogenous group of disorders related to abnormalities in elastic tissue. it may be autosomal recessive, autosomal dominant, x linked or acquired. acquired cutis laxa has developed after a febrile illness, inflammatory skin disease such a lupus eryhymatosis or erythema multiform, amyloidosis, hypersensitivity reaction to penicillin and in infants born from women who were...
