background & aim: lumbosacral pain is extremely common as age increases. spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. this study aimed at studying the frequency of instrumentation in patients referring to our center. methods & materials/patients: this retrospective cross-sectional study included 1200 patients with low back and/or radicul...
introduction: prevalence of stroke following coronary artery bypass graft surgery (cabg) is % 2.1-5.2 and associated with high mortality. the purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing cabg surgery. methods: this cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (cabg) in ima...
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
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 ...
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...
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 ...
