Abstract：
BACKGROUND: Cognitive impairment affects nearly half of vascular surgery patients, but its association with postoperative outcomes remains poorly understood. This study explores the link between preoperative cognitive performance and postoperative complications, including postoperative delirium, in vascular surgery patients.
METHODS: A prospective cohort study was conducted on vascular surgery patients aged ≥65. Preoperative cognitive performance was assessed using the Montreal Cognitive Assessment, and postoperative complications were evaluated using the Comprehensive Complication Index. The association was analyzed through multivariable logistic regression.
RESULTS: Among 110 patients (18.2 % female, mean age 73.8 ± 5.7 years), cognitive impairment was evident in 48.2 %. Of the participants, 29 (26.3 %) experienced postoperative complications, among which 11 (10 %) experienced postoperative delirium. The adjusted odds ratio for the association between cognitive performance and postoperative complications was 1.19 (95 % CI 1.02-1.38; p = 0.02).
CONCLUSIONS: Worse preoperative cognitive performance correlated with increased odds of postoperative complications and postoperative delirium in vascular surgery patients.

摘要：
背景：认知障碍影响了近一半的血管手术患者，但其与术后结局的关系仍知之甚少.这项研究探讨了术前认知表现与术后并发症之间的联系，包括术后谵妄,血管手术患者。
方法：对年龄≥65岁的血管外科患者进行前瞻性队列研究。使用蒙特利尔认知评估评估术前认知表现，术后并发症采用综合并发症指数进行评估。通过多变量logistic回归分析其相关性。
结果：在110名患者中（18.2%为女性，平均年龄73.8±5.7岁)，48.2％的认知障碍明显。在参与者中，29人（26.3%）经历了术后并发症，其中11人(10%)出现术后谵妄。认知能力与术后并发症之间的校正比值比为1.19(95%CI1.02-1.38;p=0.02)。
结论：血管外科患者术前认知表现较差与术后并发症和术后谵妄发生率增加相关。
