    Abstract:
    Patients undergoing endovascular abdominal aortic aneurysm (AAA) repair have lower perioperative morbidity and leave the hospital earlier than patients undergoing open repair. However, potential complications require continuous surveillance of endografts and there are few data regarding their long-term fate. If an open operation were well tolerated, this might be a preferable alternative. The purpose of this study was to identify patients with lower morbidity and shorter hospital stay following open AAA repair and to analyze factors that might point to open repair as the preferred approach. We performed a retrospective review of all patients who underwent AAA repair between 1995 and 2000 at our institution. All patients with ruptured aneurysms and those that required renal, celiac, or superior mesenteric reconstructions during the AAA repair were excluded. Patient demographics, preoperative comorbid conditions, intraoperative data, and postoperative complications were analyzed in detail. A total of 115 patients fulfilled the inclusion criteria. There was only one perioperative death (0.9%). The mean hospital stay was 8.1 days. A history of chronic obstructive pulmonary disease (COPD) and longer operative time were independent factors associated with prolonged hospital stay. Forty-one patients (35.6%) left the hospital in 5 or less days. Compared to the group with hospital stay >5 days, these patients had a lower incidence of COPD (7.3% vs. 25.7%, p < 0.05) and smaller-size AAAs (5.6 vs. 6.4 cm, p < 0.0001), and were more often operated on via a retroperitoneal approach (61% vs. 40.5%, p < 0.05). Their time in the operating room was less (3.5 vs. 4.5 hr, p < 0.0001), and they had less estimated blood loss (750 vs. 1500 cc, p < 0.001) and fewer transfusions (0.95 vs. 2.45 units, p < 0.0001). Patients without COPD and smaller AAAs that can be repaired via a retroperitoneal approach have a lower incidence of perioperative complications and a shorter hospital stay following open AAA repair. Until long-term results for endografts are available, our data suggest that these patients are well served with an open repair.
