 Angioplasty can be used to treat advanced peripheral artery disease to relieve the claudication, or leg pain, that is classically associated with the condition.The bypass versus angioplasty in severe ischemia of the leg (BASIL) trial investigated bypass surgery first compared to angioplasty first in select patients with severe lower limb ischemia who were candidates for either procedure.The BASIL trial found that angioplasty was associated with less short term morbidity compared with bypass surgery, however long term outcomes favor bypass surgery.
