Penetrating atherosclerotic ulcer involving the aortic arch has rarely been reported on in the literature. Acute rupture of a penetrating atherosclerotic ulcer involving the distal arch and the proximal descending thoracic aorta was found in a 78-year-old male, and he originally presented with acute-onset shoulder pain and hoarseness. Patch repair of the perforated arch and the proximal descending thoracic aorta was successfully done under total circulatory arrest.

A left ventricular rupture might be one of the most disastrous complications after a mitral valve replacement. An acute atrioventricular groove rupture (type I) was detected in a 54-year-old female diagnosed with a mitral stenosis combined with severe tricuspid regurgitation. She had a prior medical history of an open mitral commissurotomy in Japan at 30 years ago. The surgical findings suggested that the previous procedure was not a simple commissurotomy but a commissurotomy combined with a posteromedial annuloplasty procedure. After a successful mitral valve replacement and a measured (De Vega type) tricuspid annuloplasty, the weaning from a cardiopulmonary bypass was uneventful. However, copious intraoperative bleeding from the posterior wall was detected and the cardiopulmonary bypass was restarted. Exposure of the posterior wall of the left ventricle showed bleeding from the atrioventricular groove 3 cm lateral to the left atrial auricle. Under the impression of a Type I left ventricular rupture, epicardial repair (primary repair of the Teflon felt pledgetted suture, continuous sealing suture using auto-pericardial patch and application of fibrin-sealant) was attempted. Successful local control was made and the patient recovered uneventfully. The patient was discharged at 14 postoperative days without complications. We report this successful epicardial repair of an acute type I left ventricular rupture after mitral valve replacement.

PURPOSE: By virtue of advances in scientific methods and technical systems, there has been a rapid growth in the number of end stage renal disease (ESRD) patients treated using continuous ambulatory peritoneal dialysis (CAPD) as their primary renal replacement therapy. However, there are various catheter related complications that are limiting factors in patient and catheter maintenance. This study was aimed at introducing of the techniques of CAPD catheter implantation designed for reducing the complication rate, as well as conducting an investigation of the incidence of CAPD catheter related complications and patient survival and catheter survival rates. METHODS: We performed 234 cases of CAPD catheter implantation using a conventional surgical method (n=162, between January 1993 and December 1997) or a modified surgical method (n=72, between January 1998 and December 1999), and retrospectively reviewed the patient's medical records to elucidate the incidence of early catheter related complications and the catheter removal rate in relation to the surgical methods. RESULTS: There were 21 cases (23.8%) of peritonitis in the modified group, which was less than that in the conventional group (79 cases, 48.8%) (P=0.036). There were 9 cases (12.5%) of exit site and tunnel infection in the modified group, which was less than that in the conventional group (36 cases, 22.2%) (P=0.019). We were able to reduce the peritonitis as well as exit site and tunnel infection by a long segment of tunneling and immobilization of the catheter to the skin. Nine cases of leakage (5.5%) have occurred in the conventional group and one case (1.3%) in the modified group; the difference was statistically significant (P=0.046). CONCLUSION: These results indicate that our modified surgical methods can reduce the rate of early catheter related complications.
