Diagnosis of lower limb arterial disease can be based on 2D ultrasound and color Doppler ultrasound to determine the location and morphology of the lesion and assess the hemodynamics of the flow at and after the lesion.

Computed tomography of the lower limb arteries is an accurate and highly effective diagnostic imaging technique in detecting vascular diseases of the lower limbs.

Digital subtraction angiography (DSA) with catheter aspiration of thrombus is performed by inserting a catheter of appropriate diameter to the location of the thrombus, then applying negative pressure suction to remove the thrombus.

Computed tomography angiography of the lower limbs or CT angiography of the lower limbs is an imaging method that examines the vascular system using high-intensity X-rays. Contrast dye is injected into the arterial system from the femoral artery to the iliac artery triad, then X-rayed to take pictures of each cross-sectional vessel and reconstruct the image of the vascular system in three-dimensional space.
