Minimal incision aortic surgery (MIAS)

This study evaluates the clinical and economic impact of using less extensive minimal invasive aortic surgery (MIAS) for elective treatment of infrarenal aortic aneurysms (AAA) and aortoiliac occlusive disease (AIOD) in two independent surgical departments. Surgeons from two institutions conducted a prospective consecutive, nonrandomized analysis of MIAS electively performed in 80 patients. MIAS outcomes were compared with 80 consecutive elective standard open aortic procedures (40 from each institution), which were performed during the same time period. Cost analyses for MIAS and standard open repair were performed at each institution. Our results indicated that MIAS is as safe as standard open repair, is more cost-effective, and has significantly shorter hospital stays than with standard open repair.
