Antoniou GA, et al. - Researchers herein examined if better clinical outcomes are conferred by a percutaneous approach vs surgical access for standard endovascular repair of abdominal aortic aneurysms. Using the Healthcare Databases Advanced Search interface developed by the National Institute for Health and Care Excellence, they searched MEDLINE and Embase identifying four randomised controlled trials (RCTs) that compared percutaneous and cutdown endovascular aneurysm repair (EVAR); the RCTs reported on a total of 368 patients and 530 access sites. The RCTs yielded very uncertain evidence concerning the effect of percutaneous EVAR on clinically important outcomes.
