Acute Limb Ischemia Interventions.

Acute limb ischemia (ALI) is a sudden decrease in limb perfusion that threatens limb viability. Using the Rutherford classification, limbs can be categorized as threatened but viable, or irreversibly damaged, which aids clinicians in selecting appropriate therapy. Treatment options for threatened limbs include catheter-directed thrombolysis, percutaneous mechanical thrombectomy, and surgical revascularization. Potential complications from ALI and treatment include ischemia-reperfusion injury, compartment syndrome, systemic inflammatory response syndrome, multiple organ dysfunction syndrome, hyperkalemia, and bleeding.
