Peripheral arterial disease. When to consider percutaneous revascularization

Currently, percutaneous revascularization techniques are recommended for peripheral arterial disease only when limiting or disabling symptoms are present. However, the cost of these procedures is less than that of surgery and the risk is much lower. Additional prospective, randomized studies are needed for better definition of the role of percutaneous techniques in clinical practice. In the future, as techniques evolve and outcomes become better defined, this role may be expanded.
