Filter by:The study evaluates the use of a biomimetic stent (SUPERA®) and a drug eluting balloon (DEB - Passeo 18 Lux) for the treatment of recurrent and tight cephalic arch stenosis in patients with brachiocephalic fistulas. All participants will undergo angioplasty with stated devices, and be followed up with over 12 months.
In this study, we used the covered metallic segmented airway stent to treat malignant strictures involving carina and bronchi distal to carina and aimed to determine the feasibility, efficacy and safety of this technique.
POISE I study is a feasibility study for evaluating the safety and efficacy of DCB.
INGEST I Pilot study is a feasibility study for evaluating the safety and efficacy of DCBs.
Around 1-2% of people are born with a 'bicuspid' aortic valve, with only two cusps instead of the common 'tri-leaflet' valve. People with this valve develop dysfunction of the valve (narrowing or leakage) at a much earlier age. It is also more common for them to develop enlargement of the main blood vessel coming out of the heart, the aorta, and some studies suggest that they are also at higher risk of life-threatening tears in the aortic wall. Current guidelines recommend surgical replacement of the aorta at an earlier stage in these patients. The exact mechanism for the dilatation is not clear, and some studies have suggested greater 'stiffness' in the wall of the aorta. In this study, the investigators propose to 1.) study aortic size, stiffness and flow patterns using MRI in patients with bicuspid and tricuspid valves with a narrowing (aortic stenosis, 2.) measure markers in patients' blood that may be important in the process of expansion, 3.) compare the change in MRI and blood markers at before and 12 months after surgery, in patients who are due to have aortic valve replacement surgery.
A prospective observational study investigating the effectiveness and safety of integrative Korean medicine treatment in lumbar stenosis or spondylolisthesis patients with low back pain or sciatica at 3 locations of Jaseng Hospital of Korean Medicine as assessed through of pain, functional disability, walking ability, and quality of life patient-reported outcomes
This is a randomized control trial aimed to decreased radiation-induced vaginal stenosis in patients with endometrial or cervical cancer treated with post-operative external beam radiation therapy with or without brachytherapy. The intervention is an enhanced vaginal dilator model, including a silicone band placed at the desired depth of dilator insertion. The new model will be compared against the traditional vaginal dilator model used as our institutional standard of care. We hypothesize the enhanced model will improve adherence, correct use and efficacy of vaginal dilator use.
Percutaneous epidural neuroplasty (PEN) is an effective interventional treatment for radicular pain. But in some cases with wire catheter like Racz catheter, contrast runoffs were not shown to the foramen. This study will show that contrast runoff will affect the results of PEN and in cases which contrast runoff are not shown, additional transforaminal epidural blocks will affect the results of PEN by reviewing medical record, retrospectively.
To assess the effect of chiropractic distraction manipulation on postural sway and simple measures of performance in patients with the clinical diagnosis of lumbar spinal stenosis.
Aim of this study is to evaluate whether microsurgical repair or replacement of the aortic valve is a treatment option for a subgroup of patients suffering from aortic Stenosis.
