Patches of glutaraldehyde-preserved porcine pericardium were transplanted orthotopically into 20 dogs to see if they might make a satisfactory pericardial substitute. Two dogs had mediastinal infections and were excluded from this study. All animals were reoperated on at regular intervals between 15 and 300 days. In 15 dogs there were no adhesions between(More)
Glutaraldehyde-treated porcine and bovine pericardium was used to close diaphragmatic defects in 15 dogs. The animals were reoperated upon between 15 days and 15 months. There were no adherences between the heterologous patch and the adjacent structures in any dogs except one, in which the omentum was attached to the pericardium. Microscopically, the graft(More)
Quality of life after bile duct injury is a relevant health issue besides physician-oriented outcomes. A prospective study was performed to explore short- and long-term outcomes after surgical repair. We studied a cohort of patients with Strasberg E injuries who underwent Roux-en-Y jejunal anastomosis from 1990 to 2008. The Short Form Health Survey (SF-36)(More)
Although a decrease in bone mass is a well-known side effect of hormone therapy for prostate carcinoma, its clinical significance is unclear, as there is only scanty information about the incidence of fractures. Therefore, the aim of this study was to determine the risk of non-metastatic fractures in patients with prostate cancer undergoing androgen(More)
This experimental study summarizes our experience with the use of a new polytetrafluoroethylene surgical membrane as a pericardial substitute in 24 dogs. Group I consists of 10 dogs who underwent simple pericardial closure with this membrane, and in Group II, 14 dogs had pericardial closure with this membrane after cardiac procedures. There were three early(More)
OBJECTIVE Mitral regurgitation due to prolapse of the mitral leaflets frequently compromises annuloplasty repair procedures. We present a new annuloplasty ring that overcomes this difficulty, preventing displacement of the leaflets into the atrium. METHODS The 'Valve Racket' is a prosthetic ring transformed into a racket by means of handmade mesh using(More)
Satisfactory long-term clinical results with heart valves have renewed the interest in the use of mitral homografts, despite the technical difficulties with their surgical implantation. This report describes the behavior and viability of the partial mitral homograft in the ortotopic position in a chronic sheep model (n = 25). The 20 surviving animals were(More)
Surgical repair of ruptured or elongated chordae tendineae of the mitral valve is one of the most complex reconstructive techniques in cardiac surgery. Various surgical procedures have been described to repair chordal abnormalities of the anterior leaflet of the mitral valve with unpredictable results. Mitral valve replacement is usually recommended in that(More)
