To investigate superiority of off - pump CABG over on-pump CABG in terms of reducing risk ot the complication, we reviewed frequency of cerebral infarction of 698 patients who underwent CABG at our hospiati for a recent decade. Magnetic resonance angiography (MRA) of internal carotid artery (ICA) and vertebral artery (VA) was performed and the blood flow volumes were obtained in 47 patients for identifying those at the increased risk of postoperative cerebral infarction. Serum S-100β release was also measured in 18 patients to investigate early postoperative brain damage. Postoperative cerebral infarction occured in 9 of 598 (1.5%) on-pump CABG patients and 1 of 100 (1.0%) off-pump CABG patients. There was no difference in the frequency between the two procedures. The blood flow volumes of ICA and VA were significantly smaller (P < 0.05) in 25 off-pump CABG patients (ICA : 373.6 ± 86.3 ml/min, VA : 148.6 ± 52.9 ml/min) than 22 on-pump CABG patients (ICA 441.1 ± 98.9 ml/min, VA :165.1 ± 56.2 ml/min). Concentration of serum S-100β 30 minutes after surgery in off - pump CABG patients was lower in spite f the smaller blood flow volumes of neck arteries suggested that off-pump CABG is superior to on-pump CABG to reduce the risk of postoperative cerebral infarction., 原著, Original}, pages = {153--161}, title = {冠動脈バイパス術後脳梗塞予防におけるOffPump術式の有用性について : 特に術前のMagnetic Resonance Angiography (MRA)による頸動脈,椎骨動脈血流量及び血清S-100蛋白の周術期変動からみて}, volume = {30}, year = {2003}, yomi = {イノウエ, ユウホウ} }
