There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This prospective observational pilot study investigates transpharyngeal ultrasonography (TPU) as an additional neuromonitoring strategy to assess cerebral perfusion during on-pump cardiovascular surgery. In the first part of the study the investigators will investigate the feasibility of TPU for visualization of aortic arch branches including the innominate and the carotid arteries in twenty patients undergoing coronary artery bypass grafting with extracorporeal circulation (cohort 1.). In the second part the investigators plan to adopt the investigators previous experiences on TPU to a selected population of twelve patients undergoing ascending aortic and/or arch repair in deep hypothermic circulatory arrest (DHCA, cohort 2.). In contrast to cohort 1., patients in cohort 2. are exposed intraoperatively to intermittent cerebral perfusion stops or reductions due to surgical procedure, perfusion technique and their underlying disease (aortic dissection or aortic aneurysm). The investigators hypothesize that cerebral perfusion monitoring using TPU as a non-invasive technique provides a simple and real-time adjunct to assess blood flow velocity in the extracranial cephalic vessels with Doppler ultrasound. Especially in aortic arch surgery with its inherent risk of cerebral hypoperfusion TPU might be a valuable adjunct to routine.
This is a multicentre, prospective, observational post-market registry (follow-up 1 month, 1 year, 2 years, 3 years, 4 years and 5 years) to monitor the post-market clinical safety and effectiveness of the Vascutek AnacondaTM Custom Fenestrated Stent Graft in patients with a short infrarenal neck of <15mm or juxta-renal abdominal aortic aneurysms who, in the opinion of the treating physician, are anatomically suitable for the AnacondaTM Custom Fenestrated Stent Graft and for whom a customised medical device is required.
The purpose of this study is to determine whether the new RNActive®-derived prostate cancer vaccine CV9104 prolongs survival in patients with asymptomatic or minimally symptomatic metastatic prostate cancer that is castrate resistant.
The purpose of this study is to the assess the clinical performance of the BIOTRONIK PRO-Kinetic Energy stent in subjects with atherosclerotic disease of native coronary arteries.
The primary objective is the observation and description of the preliminary efficacy of resiquimod gel 0.06% on a single nodular basal cell carcinoma (nBCC) in a small group of patients.
We hypothesize that local ultrasound guided injection with corticosteroid and local anaesthetic are effective on the symptoms of GTPS.
Determine the recurrence rate of actinic keratosis (AK) lesions in patients with complete clinical clearance at the end of the previous trial SP848-AK-1101 at 6 and 12 months of follow-up.
This registry is a post market observational, prospective, multi-center registry. It is designed to evaluate patient experience with the endobronchial coil system for the relief of the emphysema symptoms and the continued collection of safety and effectiveness data on this CE Mark product.
The purpose of this study is to test the efficacy of a single injection of Canakinumab on AF recurrences within 6 months after electrical cardioversion in patients with persistent AF.
In patients undergoing laparotomy, the incidence of abdominal wall related complications such as incisional hernia is very high. In particular in patients with peritonitis undergoing laparotomy the incidence of incisional hernia is up to 54.3%. Furthermore, these patients are at great risk for development of postoperative fascial dehiscence. The gold standard of abdominal wall closure is a running slowly absorbable suture irrespective of the presence of peritonitis. Implantation of an intraperitoneal mesh potentially reduces the incidence of incisional hernia. In a series of high risk patients in which we implanted non-absorbable intraperitoneal mesh prophylactically we reduced the incidence of incisional hernia down to 3.2%.
