introduction: the purpose of this retrospective study was to evaluate the outcome following stenting over a period of 10 years in patients with chronic laryngotracheal stenosis.   materials and methods: between 2000–2010, out of 111 patients with laryngotracheal trauma, 71 underwent tracheal        t-stenting for laryngotracheal stenosis in the department of otorhinolaryngology at the governmen...

Abstract The paper deals with a theoretical study on blood flow in stenosed segment of an artery, when is mixed nano-particles. Blood treated here as couple stress fluid. Stenosis known to impede and be the cause different cardiac diseases. Since arterial wall weakened due stenosis, it may lead dilatation /aneurysm. homotopy perturbation technique employed determine solution problem for case mi...

Introduction: Mitral stenosis is a prevalent valvular disease in developing countries. Percutaneous mitral balloon valvuloplasty (PMBV) is the gold standard treatment. The main objective of this study was to assess the initial results of PMBV in patients with mitral stenosis during 16 years (2002-2018) in Mashhad, Iran. Materials and Methods: From April 2002 to March 2018, 770 patients underwen...

To investigate whether abdominal scar characteristics could predict the occurrence of cervical stenosis after abdominal radical trachelectomy (ART), we conducted a retrospective study and investigated the relationship between abdominal scar characteristics and the occurrence of cervical stenosis in patients one year after undergoing ART. The abdominal scars were evaluated using the Vancouver Sc...

Carotid Endarterectomy and the Measurement of Stenosis To the Editors: We thank Drs Barnett and Warlow for their extensive commentary on our article; we will paraphrase and briefly reply to their key points. 1. There were a limited number of high-grade stenosis pathology specimens for analysis. We did not include lesser degrees of stenosis because these are rarely subjected to endarterectomy. H...

OBJECTIVES The shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis. However, no study has evaluated changes in the F-V curve according to the degree of bronchial stenosis in patients with unilateral main bronchial stenosis. METHODS We performed an analysis of F-V curves in 29 patients with unilateral ...

OBJECTIVE To observe the relationship between coronary and carotid/cerebral atherosclerotic stenosis. METHODS Carotid/aortocranial angiography and coronary angiography were performed in 34 CAD patients complicated with symptomatic cerebral ischemia. Patients were divided into 3 subgroups according to the extent of arterial stenosis determined by angiography. There were 5 light, 4 moderate and...

This study examined the application of 64-slice spiral double-low computed tomography (CT) to evaluate the degree of coronary artery stenosis. We examined 45 patients with coronary heart disease by 64-slice spiral double-low CT and coronary angiography (CAG) to determine CT accuracy in evaluating coronary artery stenosis. Imaging analysis from 64-slice spiral double-low CT identified 199 segmen...
