There is still a considerable controversy regarding optimal treatment for patients with acute type B aortic dissection. Patients with complicated disease are particularly challenging for cardiovascular treatment. Early surgery for acute dissections of the descending aorta with life-threatening complications is known to carry a high mortality. Endovascular stent grafting is developing as an alternative treatment mainly for chronic stages of type B aortic dissection. It is not clear whether endovascular stent grafting is safe and effective in emergency treatment of acute type B aortic dissection. ⋯ Our experience provides some evidence that early mortality of life-threatening acute type B aortic dissection may be reduced by emergency endovascular stent grafting and that this form of treatment is a promising therapeutic option. Refinements, especially in stent design and application, may further improve the prognosis of patients in the life-threatening situation of complicated acute type B aortic dissection.

Pulmonary resection after chemotherapy and concurrent full-dose radiotherapy (>59 Gy) has previously been associated with unacceptably high morbidity and mortality. Subsequently neoadjuvant therapy protocols have used reduced and potentially suboptimal radiotherapy doses of 45 Gy. We report a series of 40 patients with locally advanced non-small-cell lung cancer who successfully underwent pulmonary resection after receiving greater than 59 Gy radiation and concurrent chemotherapy. Operative results and midterm survival follow-up are presented. ⋯ Pulmonary resection may be performed safely after curative intent concurrent chemotherapy and radiotherapy to greater than 59 Gy. High pathologic complete response rates and sterilization of mediastinal lymph nodes were observed accompanied by highly favorable survival rates. This experience, though promising, will require confirmation in a prospective multiinstitutional clinical trial.

Esophagogastrectomy (EG) is a formidable operation with significant morbidity and mortality rates. Risk factor analyses have been performed, but few studies have produced strategies that have improved operative results. This study was performed in order to identify prognostic variables that might be used to develop a strategy for optimizing outcomes after EG. ⋯ Morbidity and mortality of EG are significant, but most complications, including anastomotic leak, are not independent predictors of mortality. The most important complication after EG is pneumonia. Strategies to decrease postoperative mortality should include careful assessment of swallowing abnormalities and predisposition to aspiration by cineradiography or fiberoptic endoscopy. After EG, acceptable pharyngeal function and airway protection should be verified before resuming oral intake.

The safety of training residents in complex procedures has not been elucidated. In particular, the impact of resident-performed mitral valve surgery on patient outcomes is unknown. ⋯ There were no significant differences in morbidity and mortality in patients undergoing mitral valve surgery between resident and staff surgeons. It is possible to train residents to perform complex cardiac cases without adversely affecting outcomes.

Our patient was diagnosed with complete atrioventricular canal and Tetralogy of Fallot with pulmonary atresia at the age of 1 month. Then he underwent right and left Blalock-Taussig shunts at the ages of 2 months and 5 years, respectively. His cyanosis had increased at 20 years of age. ⋯ Lung perfusion scintigram showed late phase perfusion in the left lung. Chest computed tomographic scan demonstrated the left pulmonary artery. We describe the operative technique of total correction.
