Case Reports
Nonmycotic false aneurysm of aortic cannulation site presenting 26 years postoperatively.
We report the case of a 64-year-old woman who presented with a false aneurysm in the ascending aorta where arterial cannulation was done in an operation 26 years earlier. The aneurysm was excised with the ascending aorta and successfully replaced with a prosthetic graft during deep hypothermic circulatory arrest and retrograde cerebral perfusion, accompanied with concomitant procedures of mitral valve replacement and maze procedure. When the aneurysm, 3.5 x 3.0 x 4.5 cm, was removed, it showed a remarkable sharp line of demarcation between the normal aorta. Microscopic examination of the specimen was consistent with the features of a pseudoaneurysm.

Extracorporeal membrane oxygenation (ECMO) to support cardiopulmonary resuscitation (CPR) has been shown to improve survival in children and adults. We describe outcomes after the use of ECMO to support CPR (E-CPR) in adults using multiinstitutional data from the Extracorporeal Life Support Organization (ELSO) registry. ⋯ The use of E-CPR was associated with survival in 27% of adults with cardiac arrest facing imminent mortality. Further studies are warranted to evaluate and better define patients who may benefit from E-CPR.

Case Reports
Silicone y-stent placement on the carina between bronchus to the right upper lobe and bronchus intermedius.
Airway stenting using a silicone stent has become widespread for the palliation of airway stenosis. We often encounter patients with tumors involving the carina between the bronchus to the right upper lobe and bronchus intermedius. ⋯ We report three cases of malignant disease inserted with a Y-stent so that the bronchial limbs of the stent saddle the involved carina between the bronchus to the right upper lobe and bronchus intermedius. The respiratory symptoms improved immediately after the procedure.

We performed thoracoscopic surgery for pneumothorax using two-lung ventilation with low tidal volume and evaluated the feasibility and safety of this procedure. ⋯ Thoracoscopic surgery for primary spontaneous pneumothorax using two-lung ventilation with low tidal volume was technically feasible.

Hybrid revascularization has been used in minimally invasive coronary artery bypass grafting and percutaneous coronary intervention for multivessel coronary artery disease (CAD). Very few endoscopic robotic coronary bypasses on the beating heart have been reported. The aim of this study was to assess hybrid revascularization by endoscopic robotic coronary artery bypass on the beating heart with percutaneous coronary intervention in a staged approach. ⋯ Our preliminary study shows that hybrid coronary revascularization by endoscopic robotic coronary artery bypass grafting on a beating heart and subsequent stent placement is a feasible integrated approach for patients with multivessel CAD.
