Stenosis: Abnormal diameter narrowing of arterial lumen
Occlusion: Completely blocked arterial lumen with no flow present
Intermittent claudication (IC): Reproducible ischemic muscle pain provoked by exercise and relieved with rest; most commonly affects calf but can affect thigh and buttocks
Critical limb ischemia (CLI): Severe form of PAD manifested by chronic limb pain and tissue loss (ulceration and gangrene)
Acute limb ischemia (ALI): Sudden loss of blood flow that imperils limb; more typically embolic or traumatic
