Case ReportsSuccessful support and separation from veno-venous extracorporeal membrane oxygenation support in a three-month-old patient following bidirectional Glenn procedure.
While extracorporeal membrane oxygenation (ECMO) is a useful mechanism of providing support in pediatric patients with cardiopulmonary dysfunction following surgery for congenital heart disease, outcomes have varied dramatically between distinct cardiac diagnoses. Reported outcomes of ECMO support following a bidirectional Glenn procedure in patients with single ventricle physiology are uniformly poor due in part to physiological and anatomical challenges inherent to cannulation in this population. We describe a unique veno-venous cannulation that can be applied to this patient population and has allowed for successful decannulation in our practice.

Does off-pump coronary artery revascularization improve the long-term survival in patients with ventricular dysfunction?
Coronary artery revascularization with cardiopulmonary bypass (ONCAB) has been reported to carry several risks for patients with poor left ventricular (LV) function (ejection fraction <30%). Off-pump CABG (OPCAB) has been proposed to result in a better outcome, but mid- and long-term survival rates have never been compared. The aim of this study is to assess the effect of cardiopulmonary bypass on this group of patients. ⋯ Despite the reported benefits of OPCAB, there was no significant influence on the in-hospital mortality, mid-term survival or long-term survival in patients with LV dysfunction. With adequate myocardial protection in ONCAB and complete revascularization in OPCAB, similar results are achievable.

Outcomes of airway stenting for advanced lung cancer with central airway obstruction.
Approximately 30% of lung cancer patients will develop central airway obstruction (CAO). Interventional therapeutic bronchoscopy including airway stenting (AS) providing immediate and effective palliation is therefore essential to improve quality of life (QoL). However, no report has demonstrated the survival benefit of AS. ⋯ AS followed by adjuvant therapy provided a four-month increase in MST, although overall survival was not significantly changed. This study represents a single-institution experience. Although an aggressive strategy of AS is justified in order to improve symptoms and QoL, AS itself did not contribute to survival benefit.

Case ReportsThrombosis of the ascending aorta during mechanical circulatory support in a patient with cardiogenic shock.
Cardiogenic shock after percutaneous coronary intervention (PCI) is a life-threatening complication and is most often related to abrupt vessel closure. We present the case of a patient who developed cardiogenic shock after PCI and was supported with intra-aortic balloon counterpulsation and the Levitronix CentriMag short-term mechanical circulatory support. ⋯ Preoperative transesophageal echocardiography revealed a massive thrombus of the aortic root and ascending aorta despite optimal anticoagulation regimen. The patient succumbed due to multiorgan failure.

Case ReportsPneumocephalus following thoracic surgery: the implication of the epidural anesthesia is still exceptional.
Epidural analgesia is the gold standard for the management of pain after thoracopulmonary surgery. However, it is not without side-effects and complications. We report the case of a 52-year-old man who underwent left lower lobectomy for a carcinoid tumor. ⋯ Etiological assessment consisted of isotopic cisternography and cerebromedullar magnetic resonance imaging (MRI), revealing a breach in the fourth left spinal dural nerve sheath. Although it was initially suspected, the thoracic epidural was eventually excluded as the cause. Management consisted of prompt surgical repair.
