ABSTRACT

Peripheral arterial disease (PAD) is a common manifestation of atherosclerosis and is defined as any pathologic process causing obstruction to blood flow in the arteries, exclusive of the coronary and cerebral vascular beds, PAD affects a large segment of the adult population. Less than 20% of patients with PAD have typical symptoms of intermittent claudication, whereas another third have atypical exertional leg symptoms. Management strategies are governed by the severity of the disease. Imaging is necessary for planning interventions in patients with lower extremity peripheral arterial disease (PAD).[1] Noninvasive imaging modalities, including duplex ultrasonography, magnetic resonance angiography(MRA), and multi-detector computed tomography angiography (MDCTA) are available for grading lower extremity arterial disease. The prevalence increases with age, affecting up to 14–29% of elderly population. Presence of PAD is a marker of extensive atherosclerosis.[2] There are many risk factors for PAD like cigarette smoking, diabetes mellitus, hypertension, hypercholestrolemia, hyperhomocysteinemia, chronic kidney disease, insulin resistance.
