“Rapid” compression technique to treat PAD

Rapid Compression:  How Fast is Fast Enough?

Compression pump systems for peripheral arterial disease treatment and wound care are becoming more and more popular these days. As more people seek treatment for conditions caused by poor circulation, the number of cases contraindicated for surgical intervention also rises. So, to find an alternative to amputation, some medical device makers are advertising their pumps as a solution.

In general, here’s what you’ll see:

  • Cuffs/sleeves:  can cover the foot & calf or just the calf
  • Pressure:  90 – 120 mmHg

Here’s a secret, though:  most of these “arterial pumps” are nothing but DVT prophylaxes or lymphedema pumps that are modified to exert more pressure. Minor adjustments such as these have been largely untested in a clinical setting and therefore yield fairly unpredictable results.

ACI Medical is the only device maker to have uncovered the most important aspect of compression therapy as a means of treating PAD:  rapid compression (under 0.5 seconds) that serves as a close physiological substitute for brisk walking.

ArtAssist device compression sequence

Unlike all other compression pumps, ACI Medical’s ArtAssist® Arterial Assist Device® was engineered on the premise of understanding the underlying physiology of increasing arterial blood flow and focusing on results that will benefit patients with critical limb ischemia. Since developers and researchers understood how important exercise was for patients with arterial disease, they engineered a device that would bring the important physiological benefits of walking to patients with limited mobility.

Early physiological studies led by Dr. Paul van Bemmelen, Professor Andrew Nicolaides, and others showed a great understanding of the vascular system of the legs. When we exercise, our calf muscles push blood rapidly through the veins to the heart where it can be recycled and directed back towards the leg muscles with essential nutrients. Therefore, in patients who have difficulty walking, it was essential to emulate the calf muscle’s role in pumping blood without having the patient do exercise.

So, when a patient uses the ArtAssist® device, it is as if the device system is “walking” for them. Patients do not experience pain and, over a period of about three months, benefits become long-term.

September is National PAD Awareness Month

PAD stands for peripheral arterial disease. According to the US Department of Health & Human Services, PAD affects 8 to 12 million Americans. The severity of this disease’s symptoms can range from intermittent claudication (trouble walking long distances due to discomfort in the calf, thigh or hip) to gangrene and tissue death due to the utter lack of circulation in the foot.

All of us medically-conscious folks know how heart attacks are caused – if we eat too many hamburgers, spend a few too many hours lounging around, have picked up the habit of smoking, or are just genetically unfortunate, our arteries begin to harden (atherosclerosis) and plaque builds up over time, blocking important circulation from getting to the heart.

The same thing happens in our legs for the same reasons! Our PAD Category refers to a wealth of online articles about this disease that affects not only Americans, but millions of people around the world. One that I found highly informative, especially if you’re just learning about PAD, is this one published in The Times of India.

Working for a company whose medical devices come to the aid of patients suffering from severe PAD has given me both knowledge and hope for those who have run out of reliable treatment options.

For National PAD Awareness, I encourage you to educate yourself on what causes PAD, what treatments are typically prescribed, and where to look when even surgical intervention is not possible.

Since 1998, ArtAssist®…the Arterial Assist Device has helped many patients avoid PAD-related amputation. Read about what a few of them have to say.

Hope in the Face of Amputation: Mary Tells Her Mother’s ArtAssist® Device Story

Diana’s note:  I’ve been digging around on the server lately for material I could use to add to this website. I came across two wonderful stories of patients whose lives were regained because they underwent ArtAssist® Device therapy. These people wished for their testimonials to be shared with others with the hope that anyone suffering from severe PAD would know that there’s one more hope before amputation.

Mary’s mother had run out of options and was on her way toward amputation when doctors suggested the ArtAssist® Device. Here is Mary’s letter to ACI Medical on behalf of her mother (identifying information has been omitted, but it is otherwise unabridged):

November 7, 2006
ACI Medical
1857 Diamond Street
San Marcos, CA 92078-5129

To Whom It May Concern:

A little over three months ago, my mother was an active and independent 83 year-old woman, who lived alone, drove a car and took walks around the block. She began to have a very cold foot, trouble walking and developed pain and ulcers on her left foot and ankle. (She experienced pain just putting a sock on her left foot). She became unable to take her walks, in fact, she would call us because she also experienced intermittent extreme pain and could not move from one room to the next without assistance.

She was diagnosed with peripheral vascular occlusive disease. Several tests and visits to specialists indicated my mother was not a candidate for bypass surgery. Amputation was discussed, which would have been necessary if she developed gangrene. In an effort to avoid amputation, the doctors suggested she take the prescriptions Plavex and Pletal and use the ARTERIAL ASSIST DEVICE.

My mother used the ARTERIAL ASSIST DEVICE along with the Plavex and Pletal for a three-month period. I am happy to report to you that my mother is again an active and independent 83 year-old woman who is taking walks around the block! Thank you to the inventors of the ARTERIAL ASSIST DEVICE!

I am writing this letter so that someone out there who may be as severe as my mother was would ask their doctor about trying this device in an effort to avoid amputation or surgery. Sometimes there is hope when you think hope doesn’t exist.

Sincerely,
Mary H., Southgate, MI

Next week, you’ll read about a patient whose left leg has been saved not once, but twice thanks to ArtAssist® Arterial Pump Technology!

Is funding cut a false saving? – The Irish Times – Tue, Jul 24, 2012

A home device that increases arterial blood flow to the leg can help save patients’ limbs – and taxpayers’ money – so why is it no longer paid for by some HSEs, asks MICHELLE MCDONAGH

EIGHTY SEVEN-year-old Bridget O’Malley has managed to stay in her own home and avoid having a second leg amputated through the use of a cost-effective, non-invasive home device which increases arterial blood flow to the leg. However, she is the only patient in Mayo still receiving HSE funding for the ArtAssist device and one of very few in the country due to funding cuts.

ArtAssist®…The Arterial Assist Device®

Diana’s note:  Yep, that’s our ArtAssist® device! As you read the article further, you’ll see another story like Mrs. O’Malley’s, except that Mr. Conneely does not receive financial assistance for his device – he must pay out-of-pocket for it. Stateside, at ACI Medical, we’ve likewise been fighting for Medicare to reimburse for the ArtAssist® device because, as Dr. Sultan states in this article, having a patient on a device instead of undergoing a costly amputation really is “a no-brainer”.

Why ArtAssist® arterial pump therapy is unique

When you think of therapeutic pneumatic compression pumps, what comes to mind? Many might think of lymphedema or DVT prophylaxes, but it is less widely-known that arterial pump compression therapy, if correctly applied, can actually treat severe PAD.

ArtAssist Arterial Assist Device

ArtAssist®…The Arterial Assist Device®

ArtAssist®…The Arterial Assist Device® (Arterial Pump Technology) should not be confused with lymphedema or DVT prevention treatment because the ArtAssist® device solves an entirely different problem:  facilitating arterial blood flow to the places that need it, especially in the legs and feet (there are also cuffs available for arms, though it is somewhat less common).

So, for example, if you have atherosclerosis (hardening of the arteries) of the lower extremity or a diabetic foot ulcer, your problems would not be solved with a lymphedema pump, even if it has been modified to be more powerful. (Side note:  some arterial pump makers advertise that a more powerful lymphedema or DVT pump will effectively treat arterial disease. We at ACI Medical suggest that you ask for their clinical evidence.)

Depending on the nature and severity of your arterial disease, you may be better advised to use the ArtAssist® device. This device was not based on a lymphedema or DVT pump design – rather, the ArtAssist® device was designed by vascular surgeons with the goal of increasing arterial flow for patients with poor leg circulation.

Researchers have discovered that, unlike lymphedema pump technology, the ArtAssist® device promotes what we call arteriogenesis, or collateralization These two synonyms refer to the opening of small collateral arteries that already naturally bypass the obstructed artery. We all have these small collateral arteries, but when the main artery has no blockages, the collateral ones aren’t needed.

Arteriogenesis (or collateralization) explains why patients have long-term results after stopping ArtAssist® device usage

In this case, a person with a blocked artery needs to take action so that blood gets where it needs to be. Sometimes, people make lifestyle changes, such as dieting and exercising. Other times, people take medication to improve blood flow. And in more severe cases, people resort to surgery such as bypass and endovascular procedures (e.g. stenting, angioplasty, etc.).

The problem is that some people exhaust all of those options and vascular surgeons believe they have no other choice but to amputate – but that’s not true! There is actually one last shot at limb salvage for these patients, and that is the ArtAssist® device. In one clinical study, it was shown to have up to a 94% limb salvage rate even after 3.5 years.

Do be advised, though:  no one would ever recommend that you let it get to the point of amputation. As with all diseases, the earlier you solve the problem, the better.

If you or someone you know could use the ArtAssist® device as a non-surgical solution for PAD, please call our toll free number 888-453-4356 and ask to talk to Don or Sylvia. If you contact me (via WordPress, Twitter, Facebook, email, website, etc.), I will refer you to either of the two people I just mentioned as quickly as I can – we know how important limb salvage is.
