Patients with peripheral artery disease who underwent femoral artery bypass were more likely to have repeat interventions than those who underwent angioplasty with stent placement, according to data published in the Journal of Vascular Surgery. However, researcher Dr. Mahmoud B. Malas said there was some selection bias in the study because larger lesions tended to be treated with bypass. There were no significant differences in mortality and limb salvage between the two groups. A randomized study is underway to further compare the procedures.
