Evaluation of Peripheral Vascular Disease
Peripheral vascular disease is critical factor with delayed wound healing. If you are knowing how to do evaluation of the disease, it would be easily identified signs. Person will get immediate treatment and able to prevent to progress or complication of the disease.
First you should take the history of the person. You should do complete vascular examination. Check vital signs such as both side blood pressure, heart rate, height, weight should be obtained as a regular basis. Systolic blood pressure is to be within 10 to 15 mm of hg and when greater. Assess the cardiac and pulmonary assessment for atherosclerosis, arrhythmias.
Palpation of Peripheral Arteries
Palpation is to be done on regular basis for all vascular patients. American Heart Association has recommended guidelines related to pulse grading scale (0 to 3). 0 is absent, 1 is reduced, 2 is normal, 3 is bounding. In the lower extremity, the femoral, popliteal, posterior tibial and dorsalis pedis arteries should be palpated. You can palpate pulse with thepatient with sitting or supine position
Ankle Brachial Index (ABI)
This test is done with measuring blood pressure at the ankle and on the arm while person is at rest. The ankle brachial index is used to predict the severity of peripheral arterial disease. With the exercise, suppose it drops this means you probably have peripheral arterial disease.
ABI is the comparison of blood pressure of the ankle that to the arm. If the ankle pressure is less than the arm pressure, then we can evaluate a blocked artery is present in the leg. The pressure in the leg is not measured with a stethoscope but we can measure with a machine that uses ultrasound to detect the pressure.
The blood flow of the lower extremities can be detected by the Doppler ultrasound. You can easily identify the blockage present in the lower extremities.
An angiogram often called as angiography. It is an imaging test is like x-rays. Special dye is used for the x-ray. Dye injected inside the arteries. It is used to view arteries in the heart, brain, kidney and also other part of the body
Magnetic Resonance Angiogram
Magnetic Resonance Angiogram is a powerful magnetic field. It is radio waves and computer is used to evaluate blood vessels to identify abnormalities or diagnose atherosclerotic (plaque) disease.
MRA does not use ionizing radiation and might require an injection of a contrast material, which is called gadolinium, which is less likely cause an allergic reaction than iodinated contrast material.
