Intraoperative echographic studies of the ascending aorta were carried out on 100 of 222 patients having primary coronary bypass surgeries between May 1987 and December 1988. The purpose of this study was to investigate the feasibility of echographic study in evaluating the nature of atherosclerotic disease of the ascending aorta and its incidence and relationship to perioperative cerebrovascular complications in coronary bypass surgery. It was possible to obtain clear echographic images of the aortic wall in these 100 patients which were divided into two groups according to the degree of the degenerative process. Three of 13 patients (23%) (Group II) with severe atherosclerotic changes, suffered perioperative cerebrovascular complications, and early surgical mortality in 2 patients (15%) was caused by cerebrovascular complications. These complications were not seen in 87 patients with less than moderate atherosclerotic changes (Group I).
1987年5月至1988年12月期间，在222例行初次冠状动脉搭桥手术的患者中，对其中100例进行了升主动脉术中超声检查。本研究的目的是探讨超声检查在评估升主动脉动脉粥样硬化疾病性质、其发生率以及与冠状动脉搭桥手术围手术期脑血管并发症关系方面的可行性。在这100例患者中能够获得主动脉壁清晰的超声图像，根据退变程度将其分为两组。13例有严重动脉粥样硬化改变的患者（第二组）中有3例（23%）发生围手术期脑血管并发症，2例（15%）患者的早期手术死亡是由脑血管并发症所致。87例动脉粥样硬化改变程度较轻的患者（第一组）未出现这些并发症。
