Atherosclerosis is a systemic disease affecting the coronary, carotid, and lower limb arteries. Cerebrovascular accidents and lower limb ischemia are devastating postoperative complications. We aimed to evaluate the role of non-selective routine arterial duplex scanning in patients undergoing coronary artery bypass grafting (CABG).
This non-randomized clinical trial included 360 patients scheduled for elective isolated CABG who were divided into two groups: low-risk (n = 180) and high-risk (n = 180). Both groups underwent preoperative carotid and lower limb ultrasound screening for associated arteriopathy.
16 (8.9%) patients and 22 (12.2%) patients showed ≥70% carotid artery stenosis while 11 patients (6.1%) and 20 patients (11.1%) showed ≥50% lower limb arterial stenosis in the low-risk group and the high-risk group, respectively; though the difference was not statistically significant in both the cases (p > 0.1).
Routine preoperative peripheral arterial screening by sonography is a feasible and effective strategy to avoid unnecessary post CABG complications.

动脉粥样硬化是一种全身性疾病，可影响冠状动脉、颈动脉和下肢动脉。脑血管意外和下肢缺血是术后毁灭性的并发症。我们旨在评估非选择性常规动脉双重扫描在冠状动脉旁路移植术（CABG）患者中的作用。
本非随机临床试验纳入了 360 例拟行择期单纯 CABG 的患者，将其分为低危组（n=180）和高危组（n=180）。两组患者均接受术前颈动脉和下肢超声筛查，以发现相关动脉疾病。
在低危组和高危组中，分别有 16 名（8.9%）和 22 名（12.2%）患者颈动脉狭窄≥70%，11 名（6.1%）和 20 名（11.1%）患者下肢动脉狭窄≥50%；但在这两种情况下，差异均无统计学意义（p>0.1）。
术前常规外周动脉超声筛查是避免 CABG 后并发症的可行且有效的策略。
