Purpose and Method : In order to prevent stroke in perioperative period of cardiovascular surgery, we analyzed silent cerebrovascular factors. Seventy-seven patients with Coronary Artery Bypass Graft Surgery (CABG) and forty-three patients with other cardiac operations (non-CABG) were recruited and evaluated by MRI, MRA and cervical duplex ultra-sonography.<BR>Result : The frequency of the silent brain infarction in CABG group (49.4%) was not statistically significant from that in non-CABG group (41.9%). In both groups, almost all of lesions were lacunar infarctions locating in deep carebral white matter.<BR>Severe stenosis or occlusive lesions in intra and/or extracranial major arteries were more frequently found in CABG group than in non-CABG group (29.9% vs 11.6%, p=0.026). The intracranial vascular lesions rather than extracranial ones were more predominantly revealed in our series.<BR>Conclusion : To reduce the peri-and postoperative complications of patients underwent cardiovascular surgery, preoperative evaluation of stenotic vascular lesions in cervical and intracranial areas is very important.
