Randomized Controlled Trial Comparative Study Clinical Trial
Feasibility and results of awake thoracoscopic resection of solitary pulmonary nodules.
General anesthesia with single-lung ventilation is considered mandatory for thoracoscopic pulmonary resection. We assessed in a randomized study the feasibility and results of awake thoracoscopic resection of solitary pulmonary nodules. ⋯ In our study, awake thoracoscopic resection of solitary pulmonary nodules proved safely feasible. It resulted in better patient satisfaction, less nursing care and shorter in-hospital stay than procedures performed under general anesthesia.

Previous studies have shown that intraoperative transesophageal echocardiography provides important preoperative and postoperative information in various cardiac and noncardiac surgeries that may alter patient management and outcome. The role of intraoperative transesophageal echocardiography in patients in whom isolated coronary artery bypass graft surgery is anticipated has been reported only in small selected groups. This study was designed to prospectively evaluate the role of intraoperative transesophageal echocardiography in a large, nonselected group of patients undergoing primarily coronary artery bypass graft surgery. ⋯ This large consecutive, nonselected, prospective study reveals the significant impact of intraoperative transesophageal echocardiography in patients having coronary artery bypass graft surgery as a primary procedure. New findings (prebypass and postbypass) were found in 13% of patients overall, and the surgical plan was altered in 5.5% of patients. This study supports the use of intraoperative transesophageal echocardiography in patients undergoing primarily coronary artery bypass graft surgery.

Clopidogrel (Plavix) is a potent inhibitor of platelet aggregation used concomitantly with percutaneous coronary interventions and in patients with acute coronary syndromes. Its favorable effects on preventing thrombus formation may have deleterious effects on hemostasis in patients undergoing coronary surgery. ⋯ Clopidogrel within 4 days of coronary bypass surgery is associated with increased blood losses and reoperation for bleeding and, according to multivariable models, is an independent risk factor for increased transfusion requirements and prolonged ICU and hospital length of stay.

Comparative Study
The impact of aortic manipulation on neurologic outcomes after coronary artery bypass surgery: a risk-adjusted study.
Cerebral embolization of atherosclerotic plaque debris caused by aortic manipulation during conventional coronary artery bypass grafting (CABG) is a major mechanism of postoperative cerebrovascular accidents (CVA). Off-pump CABG (OPCABG) reduces stroke rates by minimizing aortic manipulation. Consequently, the effect of different levels of aortic manipulation on neurologic outcomes after CABG surgery was examined. ⋯ Aortic manipulation during CABG is a contributing mechanism for postoperative stroke. The incidence of postoperative stroke increases with increased levels of aortic manipulation.

Axillary artery cannulation for cardiopulmonary bypass is becoming increasingly used for surgery of aortic dissections for reoperations and extensively diseased ascending aortas. This can be achieved either directly or with a graft. We describe a case with a repair of chronic type A dissection in which axillary cannulation was achieved by placing the arterial cannula into a saphenous vein graft that had been anastomosed end-to-side to the axillary artery. This provides a natural, inexpensive, readily available, and more hemostatic alternative to the use of prosthetic grafts.
