Limb examination (and comparison with the opposite limb) includes:
	Hair loss
	Poor nail growth (brittle nails)
	Dry, scaly, atrophic skin
	Dependent rubor
	Pallor with leg elevation after one minute at 60 degrees (normal color should return in 10 to 15 seconds; longer than 40 seconds indicates severe ischemia)
	Ischemic tissue ulceration (punched-out, painful, with little bleeding), gangrene
	Absent or diminished femoral or pedal pulses (especially after exercising the limb)
	Arterial bruits
Additional examination by palpation and auscultation to detect abnormal aortic aneurysm or bruit
