Overall, the LIBERTY 360 study “supports aggressive management” with endovascular procedures in symptomatic patients with PAD. This is important because PAD often is inadequately treated or left untreated, according to Dr. Gray. He cited data suggesting that up to 50% of patients who undergo amputation because of lower limb claudication never even undergo a vascular evaluation.
Although there was no control group to evaluate outcomes in patients not treated or treated with another intervention, such as surgery, Dr. Gray suggested that there are encouraging results in a study that was conducted to enroll patients “with as many confounders as possible.”
Dr. Gray reported financial relationships with Abbott Vascular, Cordis, Medtronic, WL Gore, and a number of other device manufacturers.
