Carotid artery stenosis is the narrowing of lumen (inner surface) carotid artery. Usually caused by atherosclerosis, which an atheromatose plaque due to inflammation consisting necrotics, fats and cholesterol crystals. Occlusion arterial lumens makes brain lack blood supply causing damage function. Sometimes, a long period can cause permanent vascular tissue in brain. Stenosis also poses danger...

objective: lumbar spinal canal stenosis (lscs) has prominent position in spinal disorders of the elderly. ligamentum flavum hypertrophy plays a dominant role in narrowing of the lscs. there are some clues that ligamentum flavum hypertrophy is associated with diabetes mellitus. our objective was comparison of histological properties of ligamentum flavum in lumbar spinal canal stenosis patients w...

Background: The purpose of this study was validation of the Persian translation of the Swiss Spinal StenosisQuestionnaire in order to be used by Iranian researchers.Methods: A total of 104 patients with spinal stenosis diagnosis, who were candidates for operative treatment wereentered into the study. The patients completed the translated questionnaire in the 1st and the 7th days of admissionand...

background: discrete subaortic stenosis (dss) is a progressive condition. controversy still rumbles on as to whether the subaortic membrane causes aortic regurgitation (ar) and whether membrane resection reduces ar severity. we investigated the association between the left ventricular outflow tract peak gradient (lvot-pg) and ar severity preoperatively and changes in ar severity and obstruction...

background differences in causes, severities, areas of stenosis, and the association with swallowing and phonation of larynx and trachea can result into laryngotracheal stenosis (lts).this study evaluated the healing effect of bone marrow stem cells (bmscs) in experimentally induced lts dog model. methods seven dogs were enrolled. bmscs were isolated from proximal humerus and shoulder of a dog ...

background: the present study aims to evaluate the cost-effectiveness of dynamic interspinous spacer (coflex®) and static spacer (x-stop ®) compared to laminectomy (lami) in patients with lumbar spinal stenosis.   methods: a decision-analysis model was developed to estimate the cost-effectiveness. the effectiveness parameters were obtained from a systematic literature review in relevant databas...

an 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-st-elevation myocardial infarction. echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. the patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pu...

Carotid stenosis is a multidisciplinary problem that requires the involvement of specialists’ team, including cardiovascular surgeons, neurosurgeons, endovascular cardiologists, neurologists, and internists. In this consensus statement, group experts considered main stages diagnosing carotid stenosis, as well discussed, necessary prevention methods features choosing optimal treatment approach. ...

conclusions: the current study presents the highest accuracy value to diagnose the lad stenosis in the literature. results: bagging and c4.5 classification algorithms were drawn upon to analyse the data, the former reaching accuracy rates of 79.54%, 61.46%, and 68.96% for the diagnosis of the stenoses of the left anterior descending (lad), left circumflex (lcx), and right coronary artery (rca),...
