In addition to severe hypoxia and hypercapnia, acute respiratory distress syndrome (ARDS) can present with substantial hemodynamic compromise, requiring inotropic or vasopressor support or both. Either venovenous (VV) or venoarterial (VA) extracorporeal membrane oxygenation (ECMO) can be offered in this situation. However, a contemporary comparison of these two cannulation strategies has yet to be well described. ⋯ In this review of ARDS patients requiring pre-ECMO hemodynamic support, VV ECMO was not associated with worse survival or complication rates compared with VA ECMO. These data suggest that, in appropriately selected patients, it may be reasonable to initially institute VV ECMO support, reserving VA ECMO for conversion for refractory hypotension.

Coronary Artery Bypass Graft Surgery Using the Radial Artery, Right Internal Thoracic Artery, or Saphenous Vein as the Second Conduit.
It is not clear whether radial artery (RA), right internal thoracic artery (RITA), or saphenous vein (SV) is the preferred second bypass graft during coronary artery bypass graft surgery using the left internal thoracic artery (LITA) in patients aged less or greater than 70 years. ⋯ For patients aged less than 70 years, the optimal grafting strategy is using either RA or RITA as the second preferred graft. In patients aged 70 years or more, RA and RITA grafting should be used selectively. Multiple arterial grafting using either RA or RITA should be more widely utilized during coronary artery bypass graft surgery for patients less than 70 years of age.

Long segment tracheobronchial stenosis is a rare congenital anomaly that can also occur in combination with abnormal bronchial arborization. Long segment tracheal reconstruction in the setting of a supernumerary bridging bronchus has been reported; however, these repairs can be particularly complex. We present our experience using the bridging bronchus to augment long segment tracheal stenosis with a side-to-side tracheobronchoplasty. ⋯ Side-to-side tracheal reconstruction is feasible in severe cases of long segment tracheal stenosis with a right upper lobe bronchus and a bridging bronchus. This technique can be successfully applied in high-risk patients and in the neonatal period and can provide excellent midterm results.

Navigational bronchoscopy and other imaging modalities have improved the ability to evaluate pulmonary nodules/mass. Many of these lesions are located outside the bronchial airway and are difficult to access even with these devices. The Transbronchial Access Tool (Medtronic, Minneapolis, MN) allows the bronchoscopist to create a pathway from the bronchial airway, across the lung parenchyma, and into the target lesion. We are reporting the feasibility and safety of this new device. ⋯ The Transbronchial Access Tool is safe and permits access to pulmonary nodules/masses with navigational bronchoscopy.

Review
Clinical Trials in Thoracic Surgery: A Report From Ginsberg Day 2017 and Early Risers at STS 2017.
No unified source lists clinical trials relevant to general thoracic surgery. This description summarizes the current offerings across the National Cancer Institute Cooperative Group-sponsored clinical trials, and includes trials involving surgery for lung cancer and esophageal cancer, and in some instances, perioperative management of patients undergoing thoracic surgery.
