Treating Lower Arterial Occlusive Disease

 

How to proceed when a patient needs a bypass that can’t be done using the saphenous vein, and how to measure arterial flow to the foot are two novel areas that help improve a revascularization algorithm for lower arterial occlusive disease, according to Dr. Kenneth Ouriel, co-moderator of the Wednesday session, “Value of Deep Vein Grafts; New Concepts in Assessing Foot Perfusion and Improving It; More About the Angiosome Controversy; Some Ongoing CLI Trials.”

“A lot of patients don’t have a suitable bypass conduit to bring blood to the lower limb. But when the saphenous vein isn’t available, and you’re concerned an artificial graft won’t be as effective, there is another alternative,” said Dr. Ouriel, president and CEO of the New York–based clinical research firm, Syntactx.

Although the technique of using the deeper femoropopliteal vein for bypass is well described and not difficult to work with, not many clinicians think to do it, according to Dr. Ouriel. There is a widely held belief that removing it for use in an arterial bypass will lead to chronic swelling of the leg below, Dr. Ouriel said. However, the session will include a discussion to dispel this and other concerns.

Dr. Ouriel said “it’s also a vein that is not that long, so if you need a long vein for a bypass, from the top of the leg to the ankle, for example, it might not be long enough.”

Clinicians who attend this session also will be able to incorporate novel ways of quantifying perfusion to the foot, according to Dr. Ouriel. “The angiosome isn’t controversial so much as just new. Most of us didn’t learn about it in medical school, but we will explore it in depth during this session.”

The general principle of the angiosome is that arterial flow to the foot is “compartmentalized” into regions supplied by discrete vessels. This leads to seeing perfusion not only as a whole, but also in terms of specific regions, said Dr. Ouriel.

By focusing on the revascularization of the source artery to a specific angiosome, data indicate there are better rates of wound healing and limb salvage, according to Dr. Ouriel.

To round out the session are results and questions posed by a series of “exciting” trials both completed and still recruiting, including the LIBERTY, SPINACH, and BEST trials. The discussion of these trial findings will add nuance to the overall discussion about whether surgical reconstruction or peripheral intervention in patients with critical limb ischemia is appropriate and when to do it.
