Cell-based therapies involving tissue engineering represent interesting and potentially important strategies for the treatment of patients with various disorders. In this study, using a detergent-enzymatic method, we prepared an intact three-dimensional scaffold of an extracellular matrix derived from a human cadaver donor trachea, which we repopulated with(More)
Emptying of the gallbladder was studied by the simultaneous use of 99mTc-labeled diethyl-iminodiacetic acid [HIDA] scanning and real-time ultrasonography. In response to a liquid test meal the gallbladder volume was reduced for 80 min and then increased again, but the radionuclide evacuation continued and was more complete than could be explained by the(More)
PURPOSE To report an initial experience with endovascular stent-graft implantation for diseases of the descending thoracic aorta in high-risk patients. METHODS Forty-three patients (28 men; mean age 67 years, range 17-82) with 16 descending thoracic aortic dissections, 14 aneurysms, 7 contained ruptures, 3 mycotic aneurysms, 2 posttraumatic(More)
PURPOSE Endovascular stent-graft treatment for true aneurysms of the descending thoracic aorta is a valid and effective alternative to conventional surgery. A review of our experience with 21 consecutive patients is reported and technical considerations are discussed. METHODS Twenty-one patients (mean age 73 years) with true aneurysms of the descending(More)
We evaluated the antianginal effects of endoscopic transthoracic sympathicotomy (ETS) in 24 patients not eligible for coronary bypass surgery or angioplasty. In this procedure, the sympathetic chain is electrocoagulated under general anaesthesia. No major surgical complications occurred. The frequency of anginal attacks was significantly reduced (p =(More)
Fluid phase markers like erythritol and mannitol have been used to study canalicular bile secretion in the liver. It has recently been suggested that these molecules cross the ductular epithelium and thereby their biliary clearance may underestimate the canalicular bile flow. In the present study, the hepatic clearance of polyethylene glycol 900 (PEG 900),(More)
High-dose aprotinin reduces bleeding after cardiac surgery, but has also evoked concern with regard to potential side effects and hospital costs. To evaluate the effects of reduced-dose aprotinin on blood loss and need for blood transfusion, 40 patients undergoing myocardial revascularization were studied (double-blind, placebo-controlled). Postoperative(More)
PURPOSE Small pulmonary subpleural nodules are sometimes difficult to localise at thoracotomy. With the advent of minimal invasive surgery, thoracoscopic resection avoiding anterolateral thoracotomy is an attractive procedure. Since this technique does not allow manual palpation, preoperative indication of lesions is mandatory. A simple and cost-effective(More)
Pregnancy and contraceptive steroids are associated with a raised incidence of cholesterol gall stone disease. In pregnancy there is an increase in the size of the gall bladder. Investigation of hepatobiliary function in man and mammals has not established if the enlarged gall bladder is simply dilated, or if the absorptive capacity of the mucosa has(More)
