How is peripheral arterial disease in the lower extremities diagnosed?

Peripheral arterial disease in the lower extremities is typically diagnosed through a clinical examination conducted by a doctor and various diagnostic tests. The most common tests include the ankle-brachial index (ABI), which measures blood pressure in the ankle and arm, and Doppler ultrasound, which assesses blood flow in the arteries. More detailed imaging methods such as angiography may also be used if necessary to provide a detailed view of the condition of the vessels.
