What examinations are included in the assessment of lower limb blood vessels?

Generally, lower limb vascular examinations include pulse examination, ankle-brachial index (ABI), and medical ultrasound. Specific details are as follows:

1. Pulse examination: Doctors manually palpate the patient's pulses to assess blood supply in the lower limbs. Common pulse points include the dorsalis pedis artery, posterior tibial artery, and popliteal artery.

2. Ankle-brachial index (ABI): ABI is a commonly used non-invasive test to evaluate blood flow in the lower limbs. It calculates the ratio of systolic blood pressure measured at the ankle to that measured in the upper arm. A normal ABI value typically ranges between 0.9 and 1.3; a lower value may indicate arterial narrowing or blockage.

3. Medical ultrasound: This non-invasive imaging technique uses ultrasound waves to assess blood flow velocity and vessel wall structure in the lower limb vessels. It can detect conditions such as vessel narrowing, occlusion, and thrombosis.

In addition to the above tests, other diagnostic methods include angiography, magnetic resonance imaging (MRI), and CT scans. Patients should seek timely medical attention when experiencing symptoms and receive standardized treatment under a physician’s guidance, which helps promote recovery.
