• May be asymptomatic

• Acute limb ischemia → 6 Ps

• Compression of nearby nerves or veins: sudden pain, weakness, swelling, numbness in the leg

• Auscultation of the swelling: loud, harsh, continuous murmur

• Often associated with other aneurysms, esp. AAA and thoracic aortic aneurysm

• CT angiography: preoperative assessment

• Rupture: acute groin pain

• Blue toe syndrome
