Surgical management of traumatic rupture of aortic isthmus: a 25-year experience.
Traumatic rupture of the thoracic aorta is a surgical emergency with a high mortality rate. This condition requires prompt diagnosis and expeditious evaluation to improve patient survival. The aim of this study is to evaluate the outcomes of early and late management of traumatic rupture of aortic isthmus in patients with blunt thoracic trauma. ⋯ Traumatic aortic rupture remains a potentially lethal injury and an ongoing therapeutic challenge. Open surgical technique to repair the traumatic rupture of aorta is a safe procedure: postoperative outcome was excellent and the complications observed that were with aortic endoprosthetic stent-grafts were avoided.

Case ReportsEarly acute thrombosis of bioprosthetic mitral valve presenting with cardiogenic shock.
Early thrombosis of bioprosthetic mitral valves is an extremely rare occurrence. We present an unusual case of a patient with polycythemia presenting with cardiogenic shock, secondary to acute thrombosis of a bioprosthetic mitral valve which was placed 14 months prior to presentation. Our report also reviews predisposing factors and treatment options for bioprosthetic mitral valve thrombosis.

ReviewRobot-assisted thoracoscopic surgery: current status and prospects.
The most favorable advantage of robotic surgery is the markedly free movement of joint-equipped robotic forceps under 3-dimensional high-vision. Accurate operation makes complex procedures straightforward, and may overcome weak points of the previous thoracoscopic surgery. The efficiency and safety improves with acquiring skills. ⋯ Moreover, problems concerning the cost and education have not been solved. Although evidence is insufficient for robotic thoracic surgery, it may be an extension of thoracoscopic surgery, and reports showing its usefulness for primary lung cancer, myasthenia gravis, and thymoma have been accumulating. Advancing robot technology has a possibility to markedly change general thoracic surgery.

ReviewChronic lung allograft dysfunction after lung transplantation: the moving target.
Chronic lung allograft dysfunction is a major challenge in long-term management of lung transplant recipients. Both alloimmune-dependent factors (rejection) and alloimmune-independent factors contribute to the development of chronic lung allograft dysfunction. Thus, use of the term "chronic rejection" tends to be intentionally avoided among specialists in the field, although "chronic rejection" is still an acceptable lay word understood by many patients. ⋯ Until preventive and therapeutic options are refined, chronic lung allograft dysfunction will remain a major life-limiting factor. It has significant psychological, physical, social, and economic impacts. Early introduction of palliative care is another important strategy to improve patients' quality of life.

ReviewPerioperative control of blood glucose level in cardiac surgery.
It is well recognized that poor perioperative blood glucose (BG) control can increase the risk of infection, cardiovascular accidents, and even death in patients undergoing cardiac surgery. Since it has been reported that tight BG control (80-110 mg/dL) yields better outcomes in critically ill patients, it became a standard of care to control BG using intravenous insulin infusion in ICU. However, it has been debated in terms of the optimal target range whether a strict control with intensive insulin therapy is better than liberal control. ⋯ In fact, a meta-analysis of randomized clinical trials concluded that tight BG control was not associated with significantly reduced hospital mortality but was associated with an increased risk of hypoglycemia. According to the current published guidelines, it seems to be optimal to control BG level of 140-180 mg/dL in ICU. In terms of more strict BG control (110-140 mg/dL), it may be appropriate in selected patients as long as this can be achieved without significant hypoglycemia.
