Background and purpose: Recommended treatment for patients with carotid stenosis, is Carotid Endarterectomy (CEA) that is more effective in preventing stroke compared to other therapies. The purpose of this study was to evaluate morbidity and mortality rate in patients with carotid stenosis after CEA. Material and Methods: In this descriptive study, 138 patients undergoing CEA admitted in the ...
OBJECTIVES To describe our management of complex glottic stenosis in tracheotomy dependent children with severe recurrent respiratory papillomatosis. METHODS Retrospective chart review at a tertiary care children's hospital. RESULTS Three children with complex glottic stenosis secondary to severe recurrent respiratory papillomatosis were treated at our institution since 2011. Two patients h...
Abstract Objective: Diabetes mellitus (DM) is a systemic disease affecting different tissues. Hyperglycemia due to DM can lead to degenerative changes in spinal tissue. Also low data have examined the prevalence of diabetes mellitus in lumbar spinal canal stenosis individuals. Therefore the purpose of this study was determining the frequency of DM in lumbar spinal canal stenosis patients. ...
Abstract Backgraound: Renal artery stenosis is a cause of secondary hypertension. Regarding known complication of this disease and possible positive effects of renal artery angioplasty on diastolic function, this study performed among patients with renal artery stenosis. Methods: This clinical trial, with before and after design, was performed on 35 eligible patients. Patients with renal a...
Background: Balloon valvuloplasty is a relatively new technique for relief of obstruction of aortic valve. The primary results of this procedure are similar to surgical valvotomy with fewer complications and mortality. Materials and methods: One hundred fifty-five patients with congenital aortic stenosis were enrolled in this study over a period of 6 years (1991-1997). Participants were all un...
Background: The significance of cTfh cells and their subsets in atherosclerosis is not well understood. We measured the frequency of cTfh subsets in patients with different degrees of stenosis using flow-cytometry. Methods: Participants included high (≥50%; n = 12) and low (<50%; n = 12) stenosis groups, as well as healthy controls (n = 6). Results: The frequency of CCR7loPD-1hiefficient-cTfh w...
BACKGROUND AND PURPOSE A promising method for identifying hemodynamic impairment that may serve as a biomarker for stroke risk in patients with intracranial stenosis is cerebrovascular reactivity (CVR) mapping using noninvasive MRI. Here, abilities to measure CVR safely in the clinic using hypercarbic hyperoxic (carbogen) gas challenges, which increase oxygen delivery to tissue, are investigate...
this is retrospective double-blind research, which was carried out in imam khomeini hospital in order to study the accuracy of color doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color doppler before dsa angiography. the most common sites of stenosis were left internal carotid (39.5%) and right...
conclusions according to the results, there were no significant and meaningful differences comparing acs and csa groups of patients by ecds using three indicators of stenosis, plaque morphology and imt as indicators of atherosclerosis. results also display that patients with acs had more stenosis, more plaque and thicker intima–media, but these differences were not statistically significant (p ...
Background & Aim :Low density lipoprotein (LDL) particles are heterogenous with respect to their size,density and lipid composition. Among LDL particles ,the smaller and denser LDLs (small dense (sd)LDL) are believed to be atherogenic since these particles are taken up more easily by arterial wall.They are readily oxidized and have reduced affinity for LDL receptor and increased affinity for ...
