Peripheral Endovascular Arterial Intervention 2025

Peripheral Endovascular Arterial Intervention

A minimally invasive procedure used to treat blockages in the arteries of the limbs.

Duplex Ultrasound Testing

An imaging technique that uses high-frequency sound waves to visualize blood flow and detect abnormalities.

Angioplasty

A procedure to restore blood flow through the artery by inflating a balloon at the site of the blockage.

Myointimal hyperplasia

The proliferation of smooth muscle cells in the artery wall leading to stenosis after vascular interventions.

Spectral Doppler waveform

A graph that displays blood flow velocities in the vessels, helping to assess the presence of blockages.

Stenosis-free patency rate

The percentage of arteries that remain open and free of significant narrowing after an intervention.

Ankle Brachial Index (ABI)

A test that compares blood pressure in the ankle with blood pressure in the arm to assess blood flow.

Endovascular therapy

A type of intervention that involves accessing the vascular system through the skin to treat narrowed or blocked arteries.

Occlusion

The complete blockage of a blood vessel, which can lead to tissue ischemia.

Percutaneous transluminal angioplasty (PTCA)

A type of angioplasty where a catheter is used to inflate a balloon inside the artery to widen it.

Renal failure

A medical condition in which the kidneys fail to adequately filter waste products from the blood.

Drug-coated balloon (DCB)

A balloon used during angioplasty that is coated with medication to help prevent restenosis.

Velocity ratio (Vr)

The ratio used to assess the degree of stenosis, calculated by comparing peak systolic velocities at different sites.
