Acute Limb Ischemia Interventions

Acute limb ischemia (ALI) is characterized by a sudden decrease in limb perfusion that threatens the viability of the limb. ALI can result from various causes including arterial embolism, thrombosis, or trauma. The diagnosis is predominantly clinical, guided by the "6 Ps" mnemonic-pain, pallor, pulse deficit, paralysis, paresthesia, and poikilothermia-and confirmed through imaging modalities if needed. Treatment decisions are informed by the Rutherford classification, ranging from viable to irreversibly damaged limbs. Early diagnosis and timely intervention are critical for improving limb salvage and reducing amputation rates.
