A Closer Look At Non-Invasive Testing Methods For PAD

Whenever one suspects Peripheral Arterial Disease (PAD), the clinician must perform  the five non-invasive vascular testing methods that are commercially available and widely implemented.  The instruments used for measuring ABI are described under this section.

Ankle Brachial Index:

The ankle brachial index is the most well-known, non-invasive vascular testing tool. ABI test is performed with a Doppler and a blood pressure cuff. One calculates the ABI by dividing the ankle pressure by the brachial systolic pressure. An ABI of <0.9 is abnormal and  ABI values have a linear correlation with wound healing potential in lower extremity wounds.   Patients with DM may have calcified and hardened lower extremity arterial walls that cannot be readily compressed and occluded with blood pressure cuffs. This produces falsely elevated ankle pressure readings that are often in the “normal ABI range” (0.9 to 1.2) or sometimes in the non-physiological range of above 1.3. 
 
Pros.: The ABI is a relatively quick and cost-effective test for screening of PAD with known sensitivity and specificity of 90 percent or higher.  

Cons.: Calcified leg arteries in DM or dialysis patients may yield falsely elevated ABI results.

Whenever one suspects Peripheral Arterial Disease (PAD), the clinician must perform  the five non-invasive vascular testing methods that are commercially available and widely implemented. They include the ankle brachial index ABI), the toe-brachial index(TBI), pulse volume recording(PVR), transcutaneous oxygen monitoring(TCPO2) and skin perfusion pressure(SPP).

Toe-Brachial Index:

One would calculate TBI by dividing the blood pressure of the great toe by the systolic brachial blood pressure. Toe pressure of > 50mmHg is considered normal. Toe pressure < 30 mmHg is considered severely ischemic.

Pros.: The digital arteries in great toes are considered to be less affected by medial arterial calcification.

Cons.: There are site limitations such as the inability to measure toe pressure due to toe wounds or toe amputation.

Diabetes is the leading cause of neuropathy in developed countries, and neuropathy is the most common complication and greatest source of morbidity and mortality in diabetes patients. It is estimated that the prevalence of neuropathy in diabetes patients is approximately 20%. Diabetic neuropathy is implicated in 50-75% of nontraumatic amputations.

Uncontrolled diabetes leads to lots of complications in diabetic neuropathy patients. Diabetic neuropathies are a family of nerve disorders caused by diabetes. People with diabetes can, over time, develop nerve damage throughout the body. Some people with nerve damage have no symptoms. About 60 to 70 percent of people with diabetes have some form of neuropathy. People with diabetes can develop nerve problems at any time, but risk rises with age and longer duration of diabetes.

Our ranges of Neuropathy Products helps to quantitate the diabetic neuropathy. All these Diabetic Neuropathy Products are thoroughly tested by team of talented professionals, thus ensuring 100% precise result. Today, we have carved a niche as one of the major Neuropathy Care Products Exporters from India. Our Digital Biothesiometer are exported to as many as 34 countries.

One of the frequent causes of non-traumatic lower-limb amputation is Diabetes and is usually preceded by foot ulcer and infection. The reason of this ulceration is commonly a loss of protective sensation due to peripheral neuropathy, for which there is no prevention strategy. Current research promotes early detection of neuropathy so that secondary prevention measures, such as intensive foot-care education and treatment, can be used for individuals.

Since diabetic neuropathy involves the nerves, the neurological exam is a crucial part of the diagnosis. Different nerves are in charge of transmitting different sensory messages, such as temperature, touch, and vibration. Damaged nerves can’t transmit messages as well as they should, so these tests can be very helpful in narrowing down which nerves are affected.

 Some possible sensation tests are:

• Temperature: (Hot / Cold)
• Touch: Monofilament 10gm
• Vibration: Digital Biothesiometer

 

Leading Manufacturer of neuropathy therapy stimulator hospital model from Chennai.

Early identification of feet 'at risk' for ulceration is important in preventing plantar lesions in diabetic patients with insensitive feet. Plantar pressures are higher in diabetic neuropathic patients than non-diabetic and non-neuropathic Counterparts. As high plantar pressure is a proven risk factor for foot ulceration, effective screening for high plantar pressures in diabetic patients could have a major influence on the incidence of diabetic foot ulceration.
