Objective To test the hypothesis that endovascular repair of abdominal aortic aneurysm (AAA) will result in a significant reduction in mortality and morbidity rates and cost when compared with open transabdominal repair.
Background Data Since the introduction of endovascular repair of AAA this decade, multiple groups have evaluated different endovascular grafts.
Despite the excellent results reported initially, there has been a paucity of well-controlled, comparative studies looking at long-term outcome.
Methods From 1992 to 1998, the first 100 consecutive patients undergoing endovascular AAA repair (mean age 74.7, AAA size 5.6 cm) were compared to 100 patients undergoing transabdominal repair (mean age 72.9, AAA size 5.9 cm).
All patients undergoing endovascular repair received a device manufactured by Endovascular Technologies, Inc. (Menlo Park, CA) and were prospectively followed with periodic examination, contrast-enhanced computed tomography, and duplex scanning.
Of the 200 patients, 198 have been available for long-term follow-up.
Results The two groups had similar preoperative risk factors.
Surgical time (211 vs. 256 minutes, p<0.005), blood loss (326 vs. 1010 ml, p<0.005), and blood replacement (0.4 vs. 1.6 units, p<0.005) were all decreased in the endovascular group.
Median intensive care unit stay (0 vs. 2 days) and hospital stay (2 vs. 7 days) were significantly reduced in the endovascular group. (...)
