Intra-abdominal pectus bar migration – a rare clinical entity: case report

We present the case of a 20-year-old male who underwent successful surgical correction of pectus excavatum with the Highly Modified Ravitch Repair (HMRR). At 29 months the attempted operative removal of the Ravitch bar was unsuccessful despite the impression of adequate bar location on chest x-ray. Subsequent imaging with computed tomography was unclear in determining whether the bar was supra or infra-diaphragmatic due to the tissue distortion subsequent to initial surgery. Video assisted thoracoscopic surgery (VATS) successfully retrieved the bar and revealed that it was not in the thorax, but had migrated to the intra-abdominal bare area of the liver, with no evidence of associated diaphragmatic defect or hernia. Intra-abdominal pectus bar migration is a rare clinical entity, and safe removal can be facilitated by the use of the VATS technique

Seasonal-to-interannual climate prediction: ENSO, IOD and South Africa

Background: We sought to evaluate the hospital and midterm results of different surgical revascularization techniques in pediatric patients within the European Congenital Heart Surgeons Association. Methods: From 1973 to 2011, 80 patients from 13 European Congenital Heart Surgeons Association centers underwent 65 pediatric coronary artery bypass grafting (PCABG) and 27 other coronary artery procedures (OCAP; 12 patients had combined PCABG and other coronary artery procedures). Excluded were patients with Kawasaki disease. Median age at the time of coronary procedure was 2.3 years (range, 2 days to 16.9 years); 33 patients (41.2%) were younger then 12 months. An emergency procedure was necessary in 34 patients (42.5%). Results: Twelve patients (15%) died in the hospital; age at surgery (p = 0.02) and the need for an emergent procedure (p = 0.0004) were related to hospital mortality. Median follow-up time was 7.6 years (range, 0.9 to 23 years). There were 3 late cardiac deaths, all after a median time of 4 years (range, 9 months to 8.8 years) after PCABG. Fourteen patients (20.5%) presented with symptoms, including congestive heart failure (n = 10) and angina (n = 4), that were significantly associated with a low ejection fraction (p < 0.001) and the presence of moderate or severe mitral valve regurgitation (p = 0.0003). Six patients underwent a reintervention for impaired myocardial perfusion; all of them had a stenotic or atretic PCABG (p = 0.001), and the majority were symptomatic (5 of 6 patients; 83.3%; p = 0.001). Conclusions: Both PCABG and other coronary artery procedures are suitable surgical options in pediatric patients with impaired myocardial perfusion, which increases operative and midterm survival. Such population of patients needs to be followed for life to prevent and treat any possible cause of further myocardial ischemia

The vacuum bell for conservative treatment of pectus excavatum: the Basle experience

Surgical repair of pectus excavatum (PE) in childhood is a well-established procedure. Previously used operative techniques to correct PE were largely based on the Ravitch technique. Since about 10 years, the minimally invasive repair (MIRPE) by Nuss is well established. Conservative treatment with the vacuum bell to elevate the funnel in patients with PE represents a potential alternative to surgery in selected patients
