Case Reports
Aberrant right subclavian artery and axillary artery cannulation in type a aortic dissection repair.
Currently, right axillary artery cannulation and unilateral antegrade cerebral perfusion through the same cannula are preferred choices for acute type A aortic dissection repair. However, the existence of an aberrant right subclavian artery can jeopardize cerebral perfusion through the right axillary artery cannula. In this study, we intended to explain the repair of acute type A aortic dissection using right axillary artery cannulation in a patient with aberrant right subclavian artery.

Randomized Controlled Trial Comparative Study
The no-touch saphenous vein as the preferred second conduit for coronary artery bypass grafting.
Injury incurred while saphenous veins are being obtained results in poor graft patency and impairs the results of coronary artery bypass grafting. A novel method of obtaining veins, the no-touch technique, has shown improved long-term saphenous vein graft patency. ⋯ No-touch saphenous vein grafts showed a significantly higher patency rate than the radial artery grafts and the patency was comparable to the patency for left internal thoracic artery grafts. This highlights the improvement in saphenous vein graft quality with the no-touch technique and increases the number of situations in which saphenous veins may be preferable to radial artery grafts as conduits in coronary artery bypass grafting.

Comparative Study
Hypoxemia during one-lung ventilation for robot-assisted coronary artery bypass graft surgery.
Robot-assisted coronary artery bypass grafting requires continuous one-lung ventilation (OLV) to evacuate the thoracic cavity. Whether this ventilatory mode subjects patients to serious hypoxemia remains underinvestigated. ⋯ Robot-assisted two-stage coronary artery bypass surgery employing OLV could be complicated by serious hypoxemia especially at the minithoracotomy grafting stage and in patients with specific risk factors. Thus, when managing such patients, invasive monitoring and aggressive treatment of arterial desaturation are mandatory to ensure the patient's safety and procedural smoothness.
