Ankle Arterial Doppler Waveform Assessment For Surveillance Following Lower Limb Revascularisation

The primary intervention in this study is the use of ankle Doppler waveform assessment for post-revascularisation surveillance in patients with Peripheral Arterial Disease (PAD). This technique utilises continuous-wave Doppler (CWD) and pulsed-wave Doppler (PWD) to assess the blood flow in the key ankle arteries, including the dorsalis pedis artery (DPA) and posterior tibial artery (PTA).
