Grey relational analysis was used to compare the long-term outcomes of endovascular repair (EVAR) versus open repair for patients with abdominal aortic aneurysm (AAA). Patients with AAA undergoing open repair (n = 133) or EVAR (n = 88) from July 1995 to January 2009 were studied retrospectively. Compared with EVAR, longer periods of postoperative intubation and hospital stay (P < 0.001) were required for open repair. The operation time was significantly longer in open surgery than in EVAR (P < 0.001). Patients in the open repair group required larger volumes of intraoperative blood transfusion than those in EVAR (P < 0.001), and they had more of a trend of cardiac failure after surgery than those in the EVAR group. The operative mortality was similar in both groups. On follow-up, the all-cause mortality and the rates of ischemic legs within 5 years had no significant differences between the 2 procedures (P > 0.05). The grey relational grades in EVAR and open repair were 0.673 and 0.936, respectively. Compared with open repair, patients with AAAs undergoing EVAR had fewer complications in the short term and had a similar all-cause mortality in the long term.
采用灰色关联分析比较腹主动脉瘤（AAA）患者血管腔内修复术（EVAR）与开放修复术的长期疗效。对1995年7月至2009年1月期间接受开放修复术（n = 133）或EVAR（n = 88）的AAA患者进行回顾性研究。与EVAR相比，开放修复术需要更长时间的术后插管和住院时间（P < 0.001）。开放手术的手术时间明显长于EVAR（P < 0.001）。开放修复组患者术中输血量大于EVAR组（P < 0.001），且术后发生心力衰竭的趋势高于EVAR组。两组的手术死亡率相似。随访时，两种手术的全因死亡率和5年内缺血性下肢发生率无显著差异（P > 0.05）。EVAR和开放修复的灰色关联度分别为0.673和0.936。与开放修复相比，接受EVAR的AAA患者短期并发症较少，长期全因死亡率相似。
