Description
Estimated cost for Color Doppler ultrasound of the extremities 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 Color Doppler Ultrasound of the Limb Vessels include: 1. Evaluating blood flow in the arteries and veins of the limbs, 2. Diagnosing peripheral arterial disease (PAD), 3. Detecting deep vein thrombosis (DVT), 4. Assessing for aneurysms or other vascular abnormalities, 5. Monitoring the effectiveness of treatments for vascular diseases, 6. Preoperative and postoperative evaluation of limb vessels
Normal Range
For a Color Doppler Ultrasound of the Limb Vessels, normal findings typically include unobstructed blood flow, absence of plaque or thrombus, and normal vessel wall structure. Common indicators such as peak systolic velocity (PSV) in arteries should be within 10-30 cm/s, and end-diastolic velocity (EDV) should be less than 10 cm/s. The resistance index (RI) is usually between 0.5 to 0.8.
Low Values - Possible Causes
Low values, often indicated by reduced blood flow velocities, can be caused by: 1. Arterial insufficiency, 2. Peripheral artery disease (PAD), 3. Occlusion or stenosis of the vessels, 4. Vasospasm, 5. Hypovolemia
High Values - Possible Causes
High values, often indicated by increased blood flow velocities, can be caused by: 1. Arterial stenosis leading to turbulent flow, 2. Aneurysms, 3. Arteriovenous malformations (AVMs), 4. Inflammation or infection of the vessel walls, 5. Hyperdynamic states (e.g., high cardiac output conditions)
