Filter by:The primary objective of this study is to proof the concept of EP 1645 as a diagnostic tool for carotid artery atherosclerosis and plaque instability and to assess the safety and tolerability of this diagnostic agent, a monoclonal antibody fragment (Fab') conjugated with the diagnostic radionuclide 99mTc. Safety and tolerability will be determined by adverse events (AEs) observed and reported upon administration of the product and the absorbed dose of radiation.
The investigators hypothesize that the confocal endomicroscopy imaging of the biliary strictures during ERCP will differentiate between benign and malignant strictures in vivo and has increased sensitivity compared to biliary brushing/biopsy, and that direct cholangioscopic guidance of pCLE is more accurate than fluoroscopic guidance.
The objective of this study is to conduct a pilot study using biologic agents Avastin and Gleevec to treat progression of multivessel intraluminal pulmonary vein stenosis in children.
The primary purpose of the study is to measure the change in severity of symptoms and ability to function in every day activities in patients suffering from degenerative lumbar spinal stenosis after treatment with the Aperius® device.
All patients referred for coronary angiography will simultaneously be evaluated for renal artery stenosis and then stenosis more than 50% will be analyzed according to clinical conditions, risk factors and lab data.
This prospective randomized study included 60 consecutive patients suffering from anal stenosis in the period from April 2002 to December 2008. They admitted to colorectal surgery unit, Mansoura university hospital, Egypt. According to the classification proposed by Milson and Mazier(5), all patients had moderate to severe anal stenosis. There were 43 males and 17 female with a mean age 34 + 5.2 years ranging from 18 up to 63 years.
This study will evaluate the effectiveness of CorCTA by comparing the results of the test with another imaging method called Fractional Flow Reserve (FFR), which is done as a part of the cardiac catheterization.
The purpose of the study is to see if statin therapy will optimize myocardial response to cardiopulmonary bypass during aortic valve replacement (AVR) for aortic valve stenosis (AVS) (Phase I) and optimize left ventricular reverse remodeling following AVR (Phase II). Preliminary evidence indicates that perioperative statin therapy reduce mortality and morbidity following cardiac surgery. Pleiotropic effects of statins may induce myocardial preconditioning and optimize myocardial and systemic responses to cardiopulmonary bypass during AVR. Furthermore statin therapy after AVR may contribute to an optimal left ventricular reverse remodeling.
The aim of this study is to determine whether optimal medical treatment can postpone carotid endarterectomy.
Patients with severe aortic stenosis often suffer from an acquired Von Willebrand syndrome by degeneration of the polymers during passage through the narrow valve leading to turbulences. We hypothesized that the diagnosis of acquired von Willebrand syndrome influence perioperative blood loss in patients undergoing open cardiac valve replacement.
