Description

Lower Limb Vascular Color Doppler Ultrasound assesses blood flow and detects blockages or clots in leg arteries and veins—often needed for leg pain, swelling, or suspected DVT—with estimated costs of ¥30–¥70 and booking support via ChinaMedicalHub.

Main Uses

The primary purposes of a Lower Limb Vascular Color Doppler Ultrasound include: 1. Diagnosing peripheral arterial disease (PAD) by assessing for stenosis or occlusions, 2. Evaluating deep vein thrombosis (DVT) or superficial thrombophlebitis, 3. Assessing varicose veins and venous insufficiency, 4. Monitoring post-operative outcomes after vascular surgeries, 5. Guiding interventional procedures like angioplasty or stenting.

Normal Range

For a Lower Limb Vascular Color Doppler Ultrasound, the normal range typically indicates no significant stenosis or occlusion in the arteries and veins. Common indicators include: Blood flow velocity (normal arterial peak systolic velocity is usually less than 200 cm/s, and venous flow should be unidirectional and phasic with respiration), vessel wall thickness (should not show abnormal thickening), and absence of plaques or thrombi.

Low Values - Possible Causes

Low blood flow velocities can be caused by: 1. Arterial insufficiency due to severe stenosis or occlusion, 2. Venous valve incompetence leading to reflux, 3. Peripheral neuropathy affecting vascular tone, 4. Chronic venous insufficiency, 5. Post-surgical changes or scarring.

High Values - Possible Causes

High blood flow velocities might indicate: 1. Significant arterial stenosis upstream, causing increased velocity at the site of narrowing, 2. Aneurysms, which can alter local hemodynamics, 3. Arteriovenous malformations, 4. Hyperdynamic states such as high cardiac output, 5. Exercise or stress, temporarily increasing flow rates.
