Multicenter StudySurgical resection for oral tongue cancer pulmonary metastases.
The aim of this study was to evaluate the efficacy of surgical resection of oral tongue cancer (OTC) pulmonary metastases. Between 1977 and 2003, 23 OTC patients who developed 1-3 pulmonary metastases underwent metastasectomy. There were 14 men and nine women with a median age at the time of first metastasectomy of 56 years. ⋯ The median interval to systemic recurrence after lung resection was 4.1 months, and 21 out of 23 patients died of OTC (median, 9.5 months) after metastasectomy. Most patients who underwent pulmonary metastasectomy died of the disease within two years of metastasectomy. Even for patients with a solitary metastasis, surgical metastasectomy is not a recommended treatment option.

Randomized Controlled Trial Multicenter Study Comparative StudyA prospective randomized multicenter trial shows improvement of sternum related complications in cardiac surgery with the Posthorax support vest.
Sternal instability, dehiscence and mediastinitis are major causes of morbidity and mortality in cardiac surgery. The aim of this analysis is to determine the effect of a Posthorax support vest (Epple Inc, Vienna, Austria) after median sternotomy. One thousand five hundred and sixty cases were included in a prospective randomized multicenter trial. ⋯ Reoperation rates were as follows: 3.9% in group A and 0.6% in group B (P<0.05). The use of the Posthorax sternum support vest is a valuable adjunct to prevent sternum-related complications after cardiac surgery. In the 90 days follow-up period, additional surgical procedures were significantly reduced by the use of the support vest.

Multicenter Study Comparative StudySurgical ventricular reconstruction with different myocardial protection strategies. A propensity matched analysis.
The aim of this study is to compare outcomes of patients undergoing surgical ventricular reconstruction (SVR) with normothermic cardiopulmonary bypass (CPB) and beating heart or hypothermic CPB and cardioplegic arrest. Between 2001 and 2008, 588 patients underwent SVR. A propensity score matching was performed and 91 matched pairs were created: group 1 (G1) operated with normothermic CPB and beating-heart technique, and group 2 (G2) operated with hypothermic CPB and cardioplegic arrest. ⋯ Left ventricular volume reduction, ejection fraction and New York Heart Association (NYHA) class improvement were significant in the overall population; no significant differences were found between groups. The following independent risk factors for cardiac death were identified: mitral valve regurgitation, surgery <3 months from myocardial infarction, NYHA class III-IV. This study showed that outcomes following SVR are not affected by myocardial protection strategies neither in cardiac function and clinical status nor in survival.

Multicenter Study Comparative StudyIs advanced age a contraindication for emergent repair of acute type A aortic dissection?
With the general increase in human lifespan, cardiac surgeons are faced with treating an increasing number of elderly patients. The aim of our study was to investigate whether advanced age poses an increased risk for major morbidity and mortality with repair of acute type A aortic dissection. Between 2000 and 2008, 119 patients underwent emergency operation for acute type A aortic dissection at two institutions; 90 were younger than 70 years of age and 29 patients were 70 years or older. ⋯ No significant differences in operative mortality, major morbidity and actuarial 5-year survival were observed between patients >or=70 years and younger patients although there was a trend toward a lower actuarial 5-year survival in older patients. Surgery for type A acute aortic dissection in patients 70 years or older can be performed with acceptable outcomes. Hemodynamic instability portends a poor prognosis, regardless of age.

Multicenter StudyAnomalous left coronary artery from the pulmonary artery: intermediate results of coronary elongation.
A two coronary system is preferred for correcting anomalous left coronary artery from the pulmonary artery (ALCAPA); however, translocation is not always possible. In countries where neonatal arterial switch operations have not been perfected coronary transfer can be difficult. The purpose of this report is to describe the intermediate results using the coronary elongation and translocation technique in developing countries. ⋯ Color Doppler showed a patent left coronary artery; echocardiography estimated a normal left ventricular ejection fraction and improved mitral regurgitation in all patients. The technique provides an alternative approach to translocation for ALCAPA in countries where routine neonatal coronary transfer techniques may not be perfected. Intermediate results are comparable to translocation.
