ABSTRACT
Atherosclerotic peripheral arterial disease (PAD) is highly prevalent and estimated to be in 8-12 million adults living in the United States. As the population continues to age, the incidence will undoubtedly increase. Ankle-brachial index (ABI) is a ratio of the blood pressure in the ankle and blood pressure in the higher of the brachial arteries. Pulse volume recording (PVR) is performed with pressure cuffs inflated to 60 mmHg at various segments of the lower extremities. Segmental blood pressure cuffs are placed at the level of thigh, calf, ankle, foot, and big toe. The cuffs are sequentially inflated to 20 mmHg above the systolic pressure in that segment. Procedural planning can be optimized by diagnostic noninvasive imaging tests like duplex ultrasound (dUS), highresolution computed tomography angiography (CTA), and magnetic resonance angiography (MRA). The basic fundamentals for performing endovascular repair, once indications have been satisfied, begin with an in-depth understanding of vascular anatomy, collateral supply, and ability to perform an imaging work-up.
