The Dysvascular Foot & How It Leads To Infection

A “dysvascular foot” refers to a foot that has a defective blood supply. This condition is most frequently found in diabetics, and is directly caused by chronic heightened blood sugar levels which cause nerve damage over time. This nerve damage is called “neuropathy.”

According to FW Wagner,  dysvascular patients make up 80% of the thousands of patients who undergo lower extremity amputations. He created a scale to help doctors figure out how to determine the severity of a patient’s foot infection. Hopefully you will keep a close eye on your diabetic foot hygiene, so you never have to worry about such trouble.

Low Blood Supply Leads To Chronic Infection

A dysvascular foot suffers from low blood supply and oxygen circulation, so the tissues cannot heal as well as normal, healthy tissue would. Slow-healing wounds remain vulnerable to infection, especially when one considers the tremendous colony of bacteria that thrives on the feet! As we previously reported, the feet are home to more than 80 different types of bacteria — some friend, some foe. For diabetics, the risk of chronic infection leading to gangrene and amputation is very serious.

Surgery May Be Needed To Treat A Dysvascular Foot

Dr. Pinjala Ramakrishna from Nizam’s Institute of Medical Science recently spoke on the topic and pitched balloon angioplasty as a way of dilating narrowed blood vessels to provide better blood-flow. During this procedure, a small balloon is placed at the tip of a catheter and inserted into the narrowed artery. The balloon is then inflated to increase blood flow. Sometimes this procedure is done along with a stenting procedure. The stent is a small, metal mesh tube that provides structural support inside the artery to keep blood circulating. Although surgery is possible, it is still a major risk to a diabetic patient. Every type of foot wound — whether accidental or made by a surgeon’s incision — can open the body to further infection.

SteriShoe: A Friend To Dysvascular Foot Diabetics

We developed the SteriShoe UV shoe sanitizer to help make it easier for diabetics to take care of their feet. Although you may regularly wash your feet with antibacterial soap and check for skin aberrations, how clean are your shoes? Over time, our footwear can become hot, damp boxes of infectious microbes. Since we can’t just throw our shoes in the wash like regular clothes, they pose a real hazard to the dysvascular foot diabetic.

Our device harnesses UV-C light (the same kind used in hospital sanitization) to kill up to 99.9% of the microbes in footwear with one 45-minute treatment. If used daily, the UV shoe sanitizer is a great way to ensure better foot hygiene and protect yourself from harmful fungi, bacteria, yeast, and viruses. This device is FDA-approved after having passed rigorous clinical testing, and is also recommended by the American Podiatric Medical Association. Visit SteriShoe.com for more information on how to order.
