Acute recoil is a phenomenon in small arteries, such as those below-the-knee (BTK), when there is a significant reduction in luminal gain within just a few minutes after balloon angioplasty. Since the goal of BTK angioplasty is to maximize distal flow in order to heal wounds, recoil is a significant problem. As a result, reducing the incidence of acute recoil should be an important goal in improving BTK treatment.
