Moore WS, Kashyap VS, Vescera CL, et al. Abdominal Aortic Aneurysm: A 6-Year Comparison of Endovascular Versus Transabdominal Repair.Ann Surg. 1999;230:298-308. To compare endovascular repair of abdominal aortic aneurysm (AAA) with conventional transabdominal reconstruction in terms of mortality, resource utilization, cost, and long-term survival, the first 100 consecutive patients undergoing endovascular repair (mean age, 74.7 years; AAA size, 5.6 cm) were contrasted with 100 patients undergoing transabdominal repair (mean age, 72.9 years; AAA size, 5.9 cm). The device used was manufactured by Endovascular Technologies, Inc (Menlo Park, Calif). Follow-up was prospective. Although the 2 groups were similar, surgical time, blood loss, median intensive care unit stay, and hospital stay were all significantly reduced in the endovascular group. The surgical mortality (2%) and 5-year survival rate (65%) were equivalent in the 2 cohorts. Thus, it was concluded that in suitable candidates endovascular repair of AAAs can be successfully accomplished using fewer resources and at a lower cost than open repair while maintaining equivalent mortality and long-term (6-year) survival results.
