Frequently Asked Questions

Q. I just got out of the hospital where I had toes and part of my foot removed because of vascular disease. I also had a vascular bypass in my left leg. Will exercise, like on a stationary bike, help?
A. Yes, bicycling is good for overall cardiovascular health and to keep muscles working. When you are able, it is important that you start walking again. Walking uses the muscles that are affected by PAD improving circulation to the calves and lower legs. Ask your doctor to provide some specific instructions for exercise, based on your condition and the results of testing.

Q. Please explain the difference between PVD and PAD.
A. Although these terms are often used interchangeably, there is a difference between them. Peripheral vascular disease (PVD) is a broad term used to identify the group of diseases that affect the arteries, veins, and lymphatic system of the body other than the heart. PVD encompasses peripheral arterial disease (PAD), which is a more specific disease that describes a narrowing or blockage of the arteries to the legs due to the build-up of plaque and stiffening of the artery walls, known as atherosclerosis.

Q. Are there any vitamins or herbs that will help stop PAD from getting worse? I have heard that vitamins will help. Is this true?
A. There may be some potential benefit from vitamins B6, B12, E, and thiamine. However, no scientific studies have proven this. Such measures for treating PAD are of debatable value compared to the proven benefits of a supervised exercise program, anti-platelet medication, control of high blood pressure and cholesterol, and cessation of SMOKING, which by far can help the most.

Q. Over the last three to six months, my right big toe turns blue-purple when I am sitting down. When I get up to walk after about a minute, the color starts to return to my toe. Now I am noticing that my left big toe is starting to do the same thing. I went to my GP who thought it was an ingrown toenail, but I have no toe pain. I have noticed also that my feet are often cold. Circulation problems do run in my family and my mother has had blood clots and deep vein thrombosis. Should I be concerned and should I see a vascular specialist?
A. It is good that you have no pain. However, color changes could be indicative of other problems such as clots or artery compression. It is advisable to see a vascular specialist if you have any unusual symptoms, especially with your family history of vascular disease. The doctor can do some tests and initiate early treatment, if appropriate, which can prevent more significant problems.
