- Classically presents with the 6Ps: Pain,
pallor, paresthesia, pulseless, poikilothermia (cold), and
limb ischemia occurs by embolic or thrombotic causes
- Thrombotic causes are now more common due to
aging populations and advancements in vascular surgery like stents
which can be a nidus for thrombosis.
- Sudden onset of pain without prior symptoms is
more typical of embolic causes
- Preceding symptoms leading to acute ischemia
are more often from thrombosis
- Diagnosis can be clinical based on absent
pulses, ultrasound or CT angiogram
- Definitive treatment includes thrombectomy,
stenting, or bypass surgery to restore the blood flow to the distal
