Laser Therapy. Laser light pulses are being investigated as a way to remove cholesterol plaque and blood clots from the blood vessels. A 2004 report suggested that laser therapy may be particularly useful in patients with PAD who are not good candidates for bypass surgery.
PolarCath. A new type of angioplasty treatment called PolarCath opens blocked arteries by cooling and dilating them with a nitrous oxide-filled balloon. A 2004 study showed that this procedure, also called CryoPlasty therapy, has a 9-month failure rate of less than 20%, which is significantly lower the 40 - 50% failure rate reported after angioplasty or stenting procedures.
Intermittent Pneumatic Compression
Intermittent pneumatic compression (e.g., Arterial Flow, VenaFlow) is a mechanical technique normally used to treat leg ulcers or swelling from fluid build-up. The device is an inflatable fabric device that goes around the lower leg. The inflated device puts pressure on the limb. Some devices apply pressure in a wave-like motion that simulates the natural increase in blood flow during walking. A 2002 analysis of 26 studies suggested that this treatment may be beneficial for patients with PAD who cannot undergo surgery. It may even prove to be a viable alternative to medical treatments in some cases.
