peripheral vascular ultrasound
A peripheral artery ultrasound identifies blockages of blood flow (brought about by clots or plaque), aneurysms (dilations of a weakened blood vessel wall), and dissections (a split between the layers of the artery wall). This test can likewise be utilized to check the arteries after arterial bypass surgery or placement of a stent.
If you have sign and symptoms of peripheral arterial disease (PAD), you might be a candidate for a peripheral vascular ultrasound assessment. There are a few types of peripheral ultrasound test, yet each use high-frequency sound waves as to detect the problem.
LOWER LIMB ARTERIAL EVALUATION:
The purpose behind a lower limb blood vessel assessment is to identify the presence, severity and area of atherosclerosis (narrowing of the arteries brought about by plaque) in your legs. A sign and symptoms for a lower limb blood vessel assessment include leg pain while walking (claudication), leg pain at rest, leg numbness and healing, or non-healing ulcers or bruises of the legs or feet. A lower-extremity blood vessel assessment includes the following components:
PULSE VOLUME RECORDINGS AND SEGMENTAL PRESSURES:
Blood pressure cuffs are set on your thighs, calves and lower legs (the two legs). The blood pressure cuffs are inflated somewhat, and waveforms and as well as blood pressures are obtained. Blood pressures are acquired by using a special microphone, a Doppler transducer, to listen to your pulses at your ankles. This procedure is easy, painless and takes almost 30 minutes.
If the blood pressures and the waveforms are normal, it is important for you to walk on a treadmill to determine the impacts of activity on lower extremity blood flow and pulse. If the blood pressures stay normal, no further testing is required. If the blood pressures drop, a ultrasound assessment of the arteries will be performed.
In some cases an activity treadmill test isn’t needed or not tolerated by the patient. In these cases, an ultrasound scan of the lower extremity is performed without work out.
EXERCISE TREADMILL TEST:
If a treadmill test is required, you will walk on a treadmill at a moderate speed for five minutes or less. You will be asked to report any symptoms, for example, leg pain or numbness, hip pain, chest pain or dizziness when they start. At the point when you have stopped the activity, blood pressures in the two legs are acquired.
If the post-practice blood pressures in your legs are normal, no further testing is required. If the post-practice blood pressures in your legs differ significantly from those at rest, an ultrasound scan of your legs will be performed.
An ultrasound scan is an effortless and painless procedure that uses high-frequency sound waves, which are bounced off structures and moving blood inside the body. The images and signals passed are used to assess blood vessel blood flow.
A water-based gel will be applied to your legs, and an ultrasound transducer, will be used to examine the vessels in your legs. Images of your vessels and the sound of your blood flow will be recorded. This part of the assessment requires around 60 minutes.
If you are told to do peripheral vascular ultrasound or have any pain or numbness in your legs, must visit DFW Physicians and Medical Associates and get your check up done by one of best cardiologists.
