Off-pump coronary artery bypass graft (CABG) surgery has become a widely used modality and has received recognized as a minimally invasive surgery with few complications. However, for patients with severely impaired pulmonary function, further considerations have to be given to reduce the complications associated with general anesthesia. We have accumulated(More)
OBJECTIVE To evaluate the changes in cerebral blood flow during awake off-pump coronary artery bypass grafting and compare with the changes during off-pump coronary artery bypass grafting under general anesthesia, using continuous monitoring of regional cerebral oxygen saturation. METHODS The study population comprised 3 groups of patients who had(More)
Mycotic aneurysms of the coronary artery are extremely uncommon and can be very difficult to diagnose. We report a unique case of a mycotic aneurysm of the left anterior descending coronary artery with a history of two-vessel off-pump coronary artery bypass graft surgery 9 months previously. The aneurysmectomy was successful.
OBJECTIVES : The technique used to harvest the radial artery was modified, with improved results. Skeletonized radial artery conduits prepared with phosphodiesterase-III inhibitor were compared with pedicled conduits by angiography. METHODS : Isolated coronary artery bypass graft surgery that used the radial artery for conduits was performed on 83(More)
A 68-year-old man presented with a chief complaint being a cough. Based on a bronchoscopic biopsy, it was diagnosed at a nearby clinic as an advanced left lung cancer, and he was referred to our hospital. Chest computed tomography (CT) scans demonstrated a giant mass of the left lower lobe, 14 × 12 cm in size, which appeared to have invaded the left atrium(More)
PURPOSE We report our initial experience with the PAS-Port proximal anastomosis system (Cardica Inc, Redwood City, CA) using full-skeletonized radial artery (RA) in patients requiring off-pump coronary artery bypass grafting. DESCRIPTION The PAS-Port system (Cardica Inc) was used in 25 patients undergoing off-pump coronary artery bypass surgery. All(More)
Robotic skeletonizing and harvesting of the internal thoracic artery, using the da Vinci surgical system, has a number of advantages over robotic pediculed ITA harvesting. The advantages include greater blood flow, a longer conduit, and less bleeding. The technique is facilitated by use of the EndoWrist spatula cautery and fine tissue forceps (Intuitive(More)
BACKGROUND The radial artery (RA) is a useful conduit for coronary artery bypass grafting (CABG) but is susceptible to vasospasm during harvesting. We evaluated the usefulness of fasudil, a Rho kinase inhibitor, in dilating the RA graft and increasing graft free flow (GFF) compared with the conventional graft-dilating agents papaverine and(More)
OBJECTIVE It is important for coronary active perfusion systems to avoid myocardial ischemia during off-pump coronary artery bypass grafting. We have developed a new concept for a perfusion system to pump blood based on changes in helium gas volume. This system uses a conventional intra-aortic balloon pump to activate the perfusion pump. Our study used(More)
Since the development of drug-eluting stents, the conditions of coronary artery surgery have changed. The selection criteria for candidates for coronary artery bypass grafting (CABG) have become more stringent. In this era, surgeons should perform less invasive surgery to save such candidates. Off-pump coronary artery bypass (OPCAB) will become the gold(More)
