Description
Estimated cost for Lower Extremity Arterial Doppler Ultrasound at general public hospitals in China is about ¥140-320, and at Grade 3A hospitals about ¥200-400, varying by hospital tier and region.
Main Uses
The primary purposes of a Lower Limb Arterial Color Doppler Ultrasound include: 1. Assessing blood flow in the lower limb arteries, 2. Detecting and evaluating peripheral arterial disease, 3. Identifying stenosis or occlusions, 4. Monitoring the effectiveness of treatments for vascular conditions, 5. Preoperative evaluation for surgical procedures involving the lower limbs
Normal Range
For a Lower Limb Arterial Color Doppler Ultrasound, the normal range typically indicates no significant stenosis or occlusion in the arteries. Common indicators include: Peak Systolic Velocity (PSV) <200 cm/s, End Diastolic Velocity (EDV) <100 cm/s, and an Ankle-Brachial Index (ABI) between 0.9 and 1.3.
Low Values - Possible Causes
Low values, such as a reduced PSV or EDV, can be caused by: 1. Peripheral arterial disease leading to severe stenosis or occlusion, 2. Chronic venous insufficiency, 3. Severe hypotension, 4. Atherosclerosis, 5. Thrombosis
High Values - Possible Causes
High values, such as an elevated PSV or EDV, can be caused by: 1. Arterial stenosis, 2. Aneurysm, 3. Vasculitis, 4. Arteriovenous malformation, 5. Hyperdynamic circulation (e.g., in cases of high cardiac output states)
